Medical Reference Manual Adult Retrieval Victoria

Medical Reference
Manual
Adult Retrieval Victoria
January 2011
2
This document is intended as a reference manual and educational resource for ARV clinical
staff.
It is to be read in conjunction with all Ambulance Victoria Clinical Practice Guidelines.
The Clinical Practice Guidelines developed by AV for use in the field by MICA and Flight
MICA paramedics are appropriate in general scope to the range of practice of medical
Retrieval Physicians. These CPG’s are overseen by the Medical Advisory Committee and are
the initial reference point for ARV clinical practice.
The CPG’s are guidelines and do not strictly limit the scope of clinical practice of
practitioners, who in certain circumstances may reasonably work beyond or outside of the
guideline. The application of guidelines will be reviewed through the case review and audit
system, and appropriate feedback will be available.
Additions to, or alterations to guidelines will occur through the processes of the Medical
Advisory Committee (MAC)
This manual contains material and clinical recommendations that are specific to the retrieval
medical environment, which do not constitute formal guidelines.
All ARV practice occurs within the overarching policy framework of Ambulance Victoria.
This document is managed within standard AV document tracking systems as a departmental
manual. It is endorsed by the AV Medical Advisory Committee

al (retriev
val) In reespect of Rettrieval Transsfer – A patieent is consideered time criitical if the paatient has a
cliniical conditionn which pressents an imm
mediate threatt to life, limbb, cognition oor future quaality
of liife, and
• Delay inn definitive trreatment willl significantlly increase thhat outcome risk, and
• Definitivve managem
ment of that coondition or threat
t
is likelly to be achieeved by urgeent
transfer to another hospital, or
• Management of that condition deefinitively, or
o for a prolonnged interim
m period, is
beyond the
t resource capacity or clinical skill capacity of the current pprovider (or
would reesult in unaccceptable resoource drain and
a exposuree of other pattients to risk)).
Rettrieval: Th
he Need The need for retrrieval system
ms arises duee to a range of
o systems isssues. The reaal world
urbaan/rural dividde in regard to
t health infrrastructure reesults in patient isolationn and the need
d for
retriieval transferr in many criitical scenarios. The majo
ority of casess are transferrred because the
10
required level of clinical care or the necessary range of specialized clinical services are
unavailable at the referral point. This applies to both rural and metropolitan retrieval. To
optimize the quality of clinical care during transfer, specialized retrieval systems and services
are necessary.1
Retrieval services also usually provide outreach and support via clinical advisory systems
using a range of technologies.
Retrieval Systems Systems vary by State and Internationally, and there are no uniform system design standards.
Services vary in their use of platforms and crewmix (nurse, paramedic,Dr).
Drs may be employed by health dept, ambulance, by contract with private provider
(RFDS/Careflight) or services may utilise hospital personnel. A state service may incorporate
several retrieval service providers with central coordination e.g NSW (Air Ambulance NSW,
Careflight NSW, RFDS). Non government owned helicopters may be part of a state system.
Often started by passionate volunteers they are funded by community donations, corporate
sponsorship and government grants.
Australia has moved towards centralised state systems for retrieval. Central coordination
centres may incorporate nurses, paramedics and Drs, working together utilising their unique
skills and experience. Neonatal, paediatric, perinatal and adult retrieval services may be
collocated or separate. Some services have evolved due to their unique environment:
• Rugged mountainous terrain (Norway)
• Urban trauma service (HEMS London)
• European systems dealing with high density populations and high speed roadways
• Military systems
Australian systems are characterized by their need to deal with the “The tyranny of distance”
Large areas, sparsely populated, major hospitals separated by vast distances, mountain ranges
and extremes of weather and environment. In addition many advances in medicine &
technology are concentrated in major centres, increasing the need for transport. Examples
include interventional management of acute coronary syndromes and interventional radiology
e.g angio-embolisation.
Australian Retrieval Services Adult Retrieval Victoria (ARV) Managed by Ambulance Victoria
Responsible for the coordination of adult emergency retrieval services within Victoria.
ARV provides coordination of retrieval services within Victoria and provides clinical advice
relating to the management of time critical patients requiring retrieval.
The service also facilitates access to intensive care and coronary care beds across Victoria.
ARV transfers critically ill adults throughout Victoria, Tasmania and southern NSW.
Approx 3000 cases, 1500 retrievals pa
PETS (Victoria) Transfers critically ill children from hospitals throughout Victoria, Tasmania, and southern
New South Wales to the Royal Children’s Hospital and Monash Medical Centre in
Melbourne.
PETS makes the resources of paediatric intensive care available to severely ill children
throughout Victoria and offers them safe, expert inter-hospital transfer to a specialist
paediatric intensive care.
PETS also provides telephone advice to doctors, nurses, and ambulance staff on the
resuscitation of critically ill children.

Tasmania The Tasmanian Medical Retrieval Service (TMRS) operates out of Launceston & services the
whole state including the Bass Straight islands, TMRS only conducts adult retrievals.
TMRS is run in conjunction with the Tasmanian Ambulance Air Wing, the majority of work
is secondary response and interhospital transfers of critically ill patients who require specialist
care; occasionally the retrieval service will utilise the Police Air Wing where necessary.
The NETS/PETS service operates from the Royal Hobart Hospital.

Queensland Retrieval Services Queensland: paediatric, neonatal & adult retrieval services were combined
under a new retrieval service 2009.
All calls for any of the specialties and the early notification of trauma are directed to ring the
one number.
The RCQ directs callers to their area of required specialty and liaises with Queensland
Ambulance Service (QAS), Royal Flying Doctor Service, Community Helicopter Providers
and contracted services

NSW ­ MRU The Aeromedical and Retrieval Services Division (of Ambulance) comprises of the
Aeromedical Operations Centre (AOC), the Aeromedical Retrieval Unit (AMRU), fixed wing
services and rotary wing services.
Staffed by Ambulance uniformed personnel and critical care clinicians.
Provides clinical care and statewide air transport of patients from pre-hospital locations and
IHT
Most patients are transported by fixed wing aircraft staffed by flight nurses.
Urgent responses to major accidents, emergencies and neo-natal cases are usually provided by
helicopters staffed with paramedics, doctors and/or nurses.

Retrieval System Relationships In many respects, retrieval services operate at the interface of many health systems and
jurisdictions. This results in a need for special awareness and communication. Work in the
retrieval coordination and clinical response setting is often highly visible, emotive, politically
‘relevant’ and sensitive. Staff need to acquire skills in ambassadorial behavior, as well as the
important skills involved in managing pressured health workers, patients and families.

Adult Retrieval Victoria (ARV) provides an integrated, quality and timely state-wide
adult retrieval and critical care coordination service 24 x 7.
Providing telephone advice and assistance relating to the clinical care of critically ill
patients (and related administrative concerns);
Providing adult emergency retrieval services for time critical and critically ill patients
across Victoria when necessary; and
Coordinating access for critically ill adult patients to the required level of care (eg.
intensive care or coronary care beds etc).
Trauma Advice and Referral Line: ARV manages this service, connecting referral
hospitals to appropriate receiving trauma services.
When to call ARV ? Referrers are advised to contact ARV for:
o Telephone advice and assistance relating to the clinical care of critically ill
patients (and related administrative concerns);
o Adult emergency retrieval services for time critical and critically ill patients
across Victoria
o Coordination of bed access and inter-hospital transfer for critically ill adult
patients
ƒ That is, into an intensive care, high dependency or coronary care unit,
or to a destination that will provide a critical intervention or
procedure
ARV provides educational material and support to referral centres to continuously improve
referral timeliness and quality.
Patient Retrieval Retrieval is the transfer of a patient from one hospital to another in which specialised clinical
teams and transport platforms and equipment are used.
o These teams may include medical, nursing, paramedic or MICA paramedic
personnel.
o Patient retrieval provides specialised assessment and management, prior to
and during transfer of time critical or critically ill patients.
o Retrieval occurs from facilities where resources or services are inappropriate
for ongoing care to facilities that are able to provide definitive care for the
patient.

Supporting Critical Care Access Supporting Critical Care Access
The Victorian Critical Care Access webpage provides a close to real time picture of the
occupancy of Victorian Critical Care Units (ICU/HDU/CCU). It contains advanced
technology aids to facilitate monitoring of the critical care occupancy status and automated
alerts and messaging to notify key personnel within the acute health system of high levels of
occupancy and demand.
ARV hosts the website and manages website security, access, passwords and problems. ARV
uses the website to assist in the management of critical care transfers, ensuring timely and
appropriate access to critical care beds across the state.
Health services are responsible for ensuring timely data entry and for responding to high
demand alerts.
ARV recommends that the responsibility for data entry is allocated to a bed access manager
or similar role.
A hospital Executive must be nominated to receive and respond to SMS high occupancy
alerts.
Accessing the website is restricted to health services with an IP address registered in the
system.
Hospital Incident Response Data (HIRD) Management
This feature is activated during major emergencies, disasters and multi victim incidents to
allow monitoring of acute hospital and/or surge capacity and impacts. (Eg. in the event of
an epidemic or natural disaster where there is a need for monitoring of hospital status.)
Critical care access guidelines This guideline relates to the DHS Interim Critical Care Capacity Guideline.
(http://www.health.vic.gov.au/criticalcare/ccguide08.pdf)
Critical Care Access Restriction: occurs when ARV consultation mechanisms and/or the
critical care bed website indicates that a critical care patient cannot be placed in an
appropriate public or private bed within the next 6 hours.
Procedure to be followed at the time, and includes notification of Director or delegate,
and a number of external stakeholders including ICU directors.
19
Should there be need for a patient to access a bed in this setting (and no bed is available) a
defined transfer may be authorised by the Director of ARV or delegate. This process applies
for patients needing retrieval to a site where definitive care can be provided, and assumes that
such care is not available at the point of referral. The process assumes that the patient will
gain a higher level of care through this transfer. A patient should not be transferred under this
policy if all that is achieved is the same standard of care in another setting e.g. transfer of an
intubated overdose patient from ED in a metro centre with ICU consultation to the ED of a
tertiary centre.

Corporate Governance Framework of rules and practices by which a board of directors ensures accountability,
fairness, and transparency in the organisation’s relationship with its all stakeholders
(financiers, customers, management, employees, government, and the community).
This framework consists of:
explicit and implicit contracts between the firm and the stakeholders for distribution of
responsibilities, rights, and rewards,
procedures for reconciling organisational goals and outcomes with the duties, privileges,
roles, and performance of its components
procedures for proper supervision, control, and information-flows to serve as a system of
checks-and-balances.

Credentialing Policy Framework The credentialing policy framework for health practitioners is set by Federal Legislation and
administered by the Australian Health Practitioner Regulation Agency (AHPRA), and in the
local jurisdiction by the Department of Health
Credentialing within an organization is an annual process to ensure:
• services are provided within the capability and needs of the health service and its
respective campuses
• medical practitioners appointed to the health services are competent and able to fulfill
the tasks and responsibilities of their appointment
• a positive environment for medical practitioners, with a clear recognition of the
resources required to support high-quality services
• appropriate and effective clinical governance.
Performance Management & Competency ARV has a performance management system that includes continuous feedback, and an
annual review of performance and credentials. This is consistent with standard government
and DH policy and systems.
Registrar supervision and performance management follows standard training college systems
and requirements.
The structured document supporting ARV performance management is included below:
Performance Management is a process for establishing a shared workforce understanding
about what is to be achieved at an organisation level. It is about aligning the organisational
objectives with the employees’ agreed measures, skills, competency requirements,
development plans and the delivery of results.
Objectives
• Ensure that employees understand their role in working towards the goals and
objectives of ARV and Ambulance Victoria
• Ensure employees have the skills and resources they need in order to do what is
expected of them
• Promote regular feedback and discussion about contribution and professional
development.
• Recognise and encourage continued optimal performance
• Ensure effective people management processes and supportive working environments

36
Retrieval Consultant – Coordinator Daily Tasks / Activities Receive Handover
Familiarise self with in-progress jobs and critical care bed state.
Coordinate Cases
The process for telephony and case documentation is attached (flowcharts)
Follow up
Public to Private transfers (each morning) – check patient clinical status, liaise with ARV
business manager, determine need or appropriateness for transfer (and coordinate). Only
patients for whom ARV has financial responsibility need be followed up.
The coordinator will review in the ARV database, cases they performed on their previous
shift.
Data entry
After each mission, it is the responsibility of each coordinator to enter required coordination
information into the ARV database (see attached guide to the ARV database – areas with blue
background are coordinator data fields). For missions coordinated off-site, the coordination
record is returned to the ARV office by fax or mail for data entry. All data entry will be
checked / verified by an ARV admin officer.
Hospitals Database
Coordinators are required to check the hospitals database regularly for updates and
information. Where new information is obtained about a hospital (of relevance to the
database) please notify the ARV Admin Officer.
CME:
Coordinators are encouraged to take part in valid CME and research activity during waiting
periods on routine shifts.
Meetings
If available, coordinators on base will attend quality and operational issue meetings as
appropriate – including Incident Review Meetings, Case Coordination Review meetings
(monthly)
Provide Handover to next coordinator
37
Retrieval Consultant – Retrieval Physician Daily Tasks / Activities Equipment Check
Drug Check
Follow up:
All retrieval cases with medical crew will have a follow-up form attached by the ARV office
Case sheets will be stored in the ARV office.
The RP will obtain records from the previous 24 hour period and perform a 2 level follow up.
1. The receiving hospital will be contacted to ascertain patient status (with particular
reference to retrieval processes and care)
2. The referring hospital will be contacted (subsequently) to provide feedback regarding
pre-transfer patient care and preparation (where relevant), in-retrieval progress, and
information available from the destination hospital.
This information and persons contacted will be recorded on the follow-up form.
Data entry
After each mission, it is the responsibility of each Retrieval Physician to enter required
clinical information into the ARV database. For missions concluding after 2200 hrs, the PCR
may be left in the ARV office for entry the following morning by the retrieval physician on
the next shift. Each morning, the 0800-1800 shift RP will check for outstanding PCR’s from
the previous day (or provided by offsite RP’s) and enter them into the database.
Case reviews
The retrieval physician will review case records for missions where they have received a
formal case review document from the Clinical Advisor
The retrieval physician will review follow up forms filed for cases performed on their
previous shift (these may be obtained from the ARV admin officer).
CME
Retrieval physicians are encouraged to take part in valid CME and research activity during
waiting periods on routine shifts.
Meetings
If available, retrieval physicians on base will attend quality and operational issue meetings as
appropriate – including Incident Review Meetings, Case Coordination Review meetings
(monthly)
After each mission the retrieval physician will:
• Return their PCR to the ARV office
• Restock the drugs and equipment used, and sign off the register for this.
• Provide a verbal debrief on the mission to the coordinator if still on-site
Complete clinical data entry into the ARV Case database (unless the case finishes >2200 hrs)

Time Criticality Condition which presents immediate threat to life, limb, cognition or future quality of life,
and
o Delay in definitive treatment will significantly increase that outcome risk, and
o Definitive management likely to be achieved by urgent transfer to another

What factors impact on Task Time Criticality? Patient stability
o Physiology
o Diagnosis/Pathology/Natural History of Condition (Known vs Unknown)
Capability of referral site
Benefit from: retrieval team care vs intervention at receiving site
o Time to respond to intervene (outbound leg)
o Time to destination (return leg)

Destination Planning What factors are important when deciding the destination hospital for a patient?
Does patient need to move regardless? e.g small rural location:
o Early activation
o Special Needs? (neuro/CTR/trauma/PCI)
o Chronic illness? (continuity of care)
o Regional/Historical Network/Links
o Geographical zoning
o Access (airport/helipad)
o Hospital bed/ED capacity
o Insurance
o Balancing demand and capacity
o Right patient for right destination
o System monitoring and action (escalation)
For ICU/CCU patients a general principle (all other things being equal) is to move patients
with less complex issues not requiring tertiary care to non tertiary units.

Problem Solving in Retrieval Coordination Mark Putland
Superficially, the task of the CCC is a simple one. A referral site refers a critical care patient,
seeking assistance with any or all of bed finding, transport and clinical advice. The CCC has
access to up to date information about availability of different types of beds, transport
platform resources and retrieval staff resources as well as being able to provide clinical advice
from their personal critical care expertise and to source advice from appropriate experts
outside of the organisation when required. The scope for problems however is enormous.
Multiple referrals may come at once. Beds, transport platforms and retrieval staff may be in
short supply. Clinical problems can outstrip the skills of the CCC and outside experts can be
time consuming to contact or may have little grasp of the realities of the retrieval
environment. Moreover, the multiple people involved in the case can have vastly different
understandings of the problem and the best way to deal with it. These differing
understandings have been referred to as reality models(1) or frames(2). They are further
complicated by interpersonal and interagency tensions and loyalties.
The nature of complex problems The nature of complex problems has been examined in detail in the psychology literature.(1,
3) Complex problems are differentiated from simple ones by features including complexity
(multiplicity and interrelatedness of variables), dynamics (the time dependency and criticality
of the system due to ongoing actions by other agents and natural progression of the problem)
and "intransperance" (the inability of an agent to know everything about the problem before
needing to act on it or to see the immediate effect of the agent’s actions).(1) Consideration of
the retrieval-coordination environment illuminates these.
The complex system of variables at work in a single retrieval case includes the availability,
ability, fatigue and distractions of referral staff and equipment; availability of a transport
platform appropriate to the distance and accessibility of the particular referral site and the
likely receiving site, urgency of the case and size and shape of the patient; availability of a
receiving site bed and associated services and availability of retrieval staff (impacted on by
rosters, training, tasking for other cases). The case does not occur in isolation. Many cases
need to be coordinated each day so each one affects bed, platform and staff availability for the
others.
Retrieval and Coordination activities take time. In that time weather changes, patients
deteriorate, staff become fatigued, run out of rostered hours or are tasked to other activities,
and transport platforms and receiving hospital resources are lost to other cases. This
dynamism means that plans need to be made for “worst case scenarios” and must be revised
frequently.
The problem of intransperance is well known to all clinicians (although perhaps not by that
name) and is magnified for the CCC by the need to act at a distance, through the eyes and
hands of others. Discursive problems (verbal communication problems like accent and pace
of speech), fragmentation of the clinical process due to loss of visual cues and incomplete
information, uncertainty around sharing of responsibility for the patient and differing
expectations of the role of the service were all examined in a study of tensions between users
and providers of a paediatric infectious disease telemedicine service(4) and are familiar to the
CCC.
Competing “frames” or “reality models” The issue of competing “frames” or “reality models” is outlined in a review article on the
topic(2). Although from the environmental science literature there are lessons for health care
49
in it. Each agent with an interest in a problem brings with them a set of priorities, assumptions
and structural knowledge which comprise their frame which underpins the individual’s
understanding of the system in which they act and by which they predict the likely
progression of the problem and the likely effects of their efforts. The referring doctor, the
CCC, the flight coordinator, the retrieval physician and paramedic, the receiving intensivist
and others are all likely to have different frames and consultation between them, ostensibly in
the interests of clarification of the problem, can frequently in fact contribute to the ambiguity
about what the problem actually is. For example, in the case of a patient with a probable
intracranial haemorrhage in Omeo the referring nurse is concerned that the patient should
leave his care before deteriorating, the flight coordinator is concerned that the patient should
be moved in time for aircraft to be reused for the seven other tasks they had allocated it for
the day, the pilot is concerned with getting into and out of Omeo airstrip before the weather
closes in, the retrievalist is concerned with securing the airway safely and defending an
adequate blood pressure, the receiving neurosurgical registrar wants the patient to get to the
receiving hospital soon so they can be out of theatre and get some sleep before morning and is
reluctant to accept the patient directly to their overloaded tertiary centre in case the CT is
negative or the bleed is inoperable. All these frames are potentially in conflict.
Problem Solving A Google search on problem solving methodologies returns approximately 276000 results
rich with links to proprietary approaches. A common set of elements are reconfigured in a
variety of ways in most of these. The problem needs to be defined and goals established,
information needs to be collected to create a framework for predicting the progression of the
problem, and the likely effects of intervention. Actions need to be planned, decisions made
and actions executed. The effects of the actions and the strategy as a whole, need to be
reviewed, looping back if necessary to the beginning of the process again. This superficial
description of the problem solving process seems to offer little to the CCC however a there
are lessons on a closer look. Dorner(1) highlights some risks to the problem solver at the
earliest stage of goal definition.
Goals may be explicit (openly stated and obvious to the agents involved e.g. move patient X
from Stawell hospital to an urban ICU) or implicit (assumed by the problem solver e.g. ensure
patient X is no worse for being transported). Difficulties occur when one agent’s implicit
goals are not obvious to the other agents involved. The GP in Stawell may have a full clinic
waiting for her once she is finished supporting patient X; she has an implicit goal, that to her
is too obvious to need stating, of getting back to the clinic in order to attend to her other
patients. This will affect her whole approach to the case but the CCC may be entirely unaware
of the importance of it to her. Implicit goals of the CCC might include maintaining safety and
satisfaction of staff, maintenance of goodwill in receiving units, nurturing the development of
experience and expertise in referral units and conservation of relations with platform
providers. By working to make implicit goals explicit the problem solver becomes more
aware of the factors affecting their own thinking in difficult situations and is able to better
engage others in achieving these goals. Different sets of implicit goals can be seen as different
frames. In the discussion of competing frames cited above(2) the following techniques for
dealing with this problem are outlined. One can attempt to convert others to one’s own frame
by recourse to scientific reasoning (which works well as long as one is dealing with people
who have a fundamentally scientific frame to start with), by persuasive communication
(which is very personality dependant) or by an oppositional mode of action where a power
differential is used to impose one’s frame on others (which depends upon such a power
differential existing in one’s favour and which may have ongoing costs in terms of good will).
Alternatively a process of negotiation and compromise can be used to try to get the most
satisfactory outcome possible accepting the differences in frames or a dialogical approach can
be used where open discussion between the agents leads to frame enlargement: each agent
adapts their frame to incorporate some elements of the other’s frames also such that all the
agent’s goals start to become synchronous. This last technique is at the centre of Crisis
50
Resource Management where the importance of all “being on the same page” is stressed. A
team briefing in which all team members voce their understandings of the mission brings all
the different conceptions into synchrony with one another. Conference calls and video
conferencing are powerful tools for this. (5)
Goals may be clear or unclear. An example of an unclear goal is to “help hospital Y with a
multi-casualty traffic accident. Such an unclear goal does not allow for prioritised and
effective action. Breaking such a goal into specific elements produces clear goals (e.g.
establish the magnitude of the problem and the local capacity to manage it, engage the major
trauma services, provide case-by-case clinical advice and arrange evacuation of specific
patients).
Dorner also refers to “goal degeneration” where the problem solver becomes distracted by
achievable but largely irrelevant goals, losing sight of the big picture. In difficult situations
this can become self-perpetuating resulting in a “flow situation” where challenging but
achievable short-term goals are generated and accomplished again and again to the detriment
of the overall aims. The retrievalist is perhaps more at risk of this than the CCC, for example
treating an unstable and complex patient who is not responding to treatment in a small rural
setting the retrieval physician first inserts an extra intravenous line, then spends an hour trying
to insert an arterial line, then places a central line but for want of a chest X ray arranges for a
portable ultrasound machine to be brought from the maternity unit and attempts to use
ultrasound to confirm the placement of the line. Next, having sourced the ultrasound machine
with some difficulty, the retrievalist decides to do a bedside Echocardiogram and examine the
liver for signs of congestion. Meanwhile the more important issues of the patient’s labile
blood pressure, galloping sepsis and distance from definitive care are being avoided. The
retrievalist has been drawn into a flow situation and has lost situational awareness.
Multiple Simultaneous Problems Attention needs to be given to the issue of dealing with multiple simultaneous problems. The
CCC workload is highly variable and during busy periods 12-20 new cases a day might be
referred, often clustered together in the late afternoon (Dr Marcus Kennedy, Unpublished
Data on ARV Case Volume Loads 2010, 2010 November 23). Strategies for dealing with
multiple simultaneous problems include finding a central problem, the solution of which will
solve multiple problems, prioritisation (triage), delegation, compromise and attempts to
reshape the system such that negatively linked goals become positively linked.
Finding a central problem depends on identifying interdependencies between problems. The
CCC is uses an intimate knowledge of the intricacies of the state critical care system to take a
systems view of retrieval problems. When multiple patients need to be moved around the state
into and out of beds of varying acuity and specialisation via multiple different transport
platforms using multiple crew configurations getting the right patient to the right bed the right
way can avoid many subsequent problems.
Prioritisation of problems Prioritisation of problems is familiar to critical care physicians and is formalised in
emergency medicine in the Australasian Triage Scale.(6) When prioritising problems it is
important to recognise that importance and urgency are independent of one another. A
problem is urgent if the outcome will be altered adversely by a short delay to solution
however if the adverse outcome is trivial, or at least acceptable, then the problem might be
prioritised below a more important but less urgent one. A third factor to consider in
prioritisation is achievability. On occasion it may be appropriate to solve several easy but
fairly unimportant or non-urgent problems while leaving more important or time critical ones
unmanaged. This counter-intuitive approach has the advantage of de-cluttering the thinking
space of the problem solver but there is a danger of being seduced by the attraction of dealing
51
with easily soluble problems at the expense of important but difficult ones (the “flow
situation” referred to above).
Delegation Delegation is at the centre of effective crisis resource management. The CCC has a number of
other people to use when multiple problems need to be addressed simultaneously including
the retrieval administration support officer (RASO), the administrator, the retrieval physician
and registrar and ambulance logistic staff such as the flight coordinator. While delegation
makes the most of the available resources the delegator must maintain oversight of, and
responsibility for, tasks thus distributed.
Compromise Compromise is almost universally required in the retrieval coordination environment. A
referral hospital invariably wants the patient removed immediately, the receiving site
frequently needs time to prepare for reception of the patient and transport is frequently
delayed for logistical and distance reasons. Moreover, some patients require some immediate
stabilisation before transport.
The CCC has little opportunity in day to day work to reshape the system however providing
feedback to management relating to issues arising from cases may allow for this to occur.
In conclusion the CCC needs to assess and prioritise multiple complex problems at any given
time, the solutions to which will be interdependent on each other. They are a central point for
the interaction of people from all over the health care system all of whom will bring different
skills, assumptions, priorities and pressures and who must be made to work in a common
direction for the sake of the patient. The skills required include use of specific critical care,
aeromedical and health care system knowledge, time management, triage and delegation skills
and interpersonal communication and negotiation skills.

Crisis Resource Management and Retrieval Coordination Belinda Carne
Crisis Resource Management is the term given to that area of human behaviour that concerns
itself with the management of medical crises. (1;2) It is a term adapted from the aviation
industry, which uses Crew Resource Management training as one of its tools to improve flight
safety. Research, particularly in the aviation industry, has identified certain behaviours that
contribute to poor outcomes in crises (3) and it is from here that a list of key points of Crisis
Resource Management has been developed. (4;5) It is thought that the practice of these
behaviours is likely to improve the management of crises with a resultant increase in patient
safety. These behaviours are particularly relevant in the setting of Retrieval Coordination,
which involves work of high complexity often performed under pressure, and requires liaison
between multiple stakeholders to achieve the best possible outcome for time critical and
critically ill patients (6).
The key points of Crisis Resource Management are:
1. Know your environment
2. Anticipate and plan
3. Take a leadership role
4. Communicate effectively
5. Call for help early
6. Allocate attention wisely and use all available information
7. Distribute the workload and utilize all available resources
Know your environment The first point, that of ‘know your environment,’ has applicability in both the physical and
cultural domains. The most obvious environment for the Retrieval Coordinator is that of the
office in which they work. A working knowledge of the location and function of
telecommunications equipment is needed to facilitate call taking, conferencing, and
documentation. Coordinators need to know where to access information relating to location
and clinical resources of referring hospitals, as well as platform options for those locations
(6). Similarly, information regarding the capabilities of receiving hospitals is needed to
streamline the process of finding a suitable destination for the patient. There would be no
point in successfully finding an ICU bed in a hospital without neurosurgical capability for a
previously well patient with a significant extradural haemorrhage. The smooth performance of
this often time pressured job relies upon a working knowledge of where things are, and how
they work. Knowledge of the environment also includes knowledge of the human resources
therein. People such as the Flight Coordinator, RASO (Retrieval Administration Support
Officer), Doctors and Paramedics form part of the environment, and knowledge of who is
working and what their capabilities are can also smooth the path of retrieval.
Leadership The cultural environment has the capacity to impact on the shape a retrieval takes. Studies
have shown that a direct link exists between team culture and performance (7). The retrieval
environment is one that brings together professionals from different disciplines and cultures.
This has the potential to create conflict and role confusion. Prominence, sociability and task
orientation are three dimensions in which interpersonal behaviour can vary. In general, ‘the
more education the team members have, the more prominent and task-oriented they are.’ (8)
A concomitant relatively lower level of sociability can impact upon the ability of individuals
to form effective teams. One of the roles of a Retrieval Coordinator is to be aware of the
cultural environment in which they work, and to be aware of the impact of this environment
53
on team performance. An awareness that leadership style can influence team dynamics is also
of value (9). Participative decision making processes can increase the degree of team
identification experienced by staff, whilst a collaborative approach to dealing with conflict
can create an increase in team members‘ sense of interdependence, and can reduce social
distance. These outcomes can all contribute towards creating a more cohesive, professional
and highly functioning team (11).
Anticipate and Plan ‘Anticipate and plan,’ is relevant at all stages of the co-ordination process. Thinking ahead to
what might happen, and developing a plan for that contingency can contribute to the success
or otherwise of a mission. Anticipation and planning begins with the start of the co-ordination
shift, when a handover and familiarisation with the critical care bed status occurs. It can be
anticipated that this knowledge will be needed during the day. Planning ahead to acquire this
knowledge at the start of a shift contributes to smoother management of retrievals later on.
Anticipation and planning is also relevant when the time comes for crew mix selection. Tools
such as the Crew Mix Grid can assist with this task (6), but a clinical appreciation of the
potential for deterioration is also necessary. An example of this includes the patient with a
significant ingestion of tricyclics antidepressants. A request for retrieval may be made due to
an impaired conscious state. Although the clinical situation at the time of the call may fit the
requirements for paramedic tasking, the potential for delayed onset of arrhythmias and
seizures (11) would suggest that the crew include a Retrieval Physician. Failure to anticipate
clinical deterioration can result in the necessity to task a second crew, which can delay the
patient’s access to definitive care. Similarly, a failure to anticipate the effect of weight on
transport options can result in the wasted deployment of aircraft at significant cost in both
financial and clinical terms.
It is recognised that the performance of complex tasks is impaired by factors to do with the
self (fatigue, inexperience, ill health, lack of knowledge), and environmental factors
(interruptions, handovers, production pressure, equipment failure) (14;15). These issues,
together with the HALTS factors - being hungry, angry, late, tired or stressed, can be partly
avoided by forward planning. The use of checklists has been shown in a variety of settings to
make a significant improvement in a person’s ability to successfully complete a series of
necessary tasks (16;17), and this is reflected in Adult Retrieval Victoria’s use of the
Coordinator Record (6). Another area in which checklists are useful is in the area of skills
competency. Having a skills checklist completed for each crew member allows the retrieval
coordinator to have confidence that a certain skill set is present prior to tasking.
Taking a Leadership Role is necessary in the retrieval coordination setting. There are often a
large number of stakeholders involved in any given retrieval, and there are often conflicting
agendas. The coordinator acts as the leader of the retrieval process, balancing the needs of the
individual patient, with the needs and requirements of the other stakeholders – referring
hospital, receiving hospital, retrieval team and platform coordinators. This leadership role is
best performed in a participative manner (11), but at times will need a more authoritarian
approach in settings such as that of Defined Patient Transfer (16). Even then, the leadership
style should employ the least confrontational approach consistent with the goal, anticipating
that maintaining good relationships will contribute to optimal outcomes in future interactions.
A hands-on leadership style which encourages a shared sense of purpose, a focus on results
and a collaborative environment can result in improvements in outcomes for patients (17).
Involving the team in the discussion on how to achieve a particular goal, can be more
effective than issuing a set of directives (18). Part of the leadership role can also include the
provision of debriefing, or directing those in need to peer support or counselling services
provided by Ambulance Victoria. Coordinators also need to recognise when they themselves
are affected by stress, and need to develop appropriate self care behaviours. Leadership in the
area of Clinical Governance – formalising lines of responsibility and accountability and
creating systems for quality improvement, can also impact on patient safety (19). Activities
such as routine peer coordination case review with feedback, review of retrievalist case
54
sheets, and incident review are examples of quality improvement activities within the retrieval
environment. The importance of continually examining systems and outcomes was
highlighted in the 1999 United States Institute of Medicine report ‘To Err is Human,’ and in
the 2001 report ‘Crossing the Quality Chasm’ which expanded on the original theme of
preventable error management (20).
Effective Communication Effective Communication is one of the most important factors in Crisis Resource
Management. Effective communication in the retrieval environment is crucial to the success
of a mission, and relies upon a reliable infrastructure (21) as well as excellent communication
skills. Skills likely to increase the chance of effective communication, particularly in times of
conflict, include the acknowledging of different perspectives (22), concentrating on the issue
at hand without recourse to personal attack (23), aiming for assertiveness rather than
aggression or submission (24), and taking the advice found in Desiderata – to ‘speak your
truth quietly and clearly and listen to others’ (25). These approaches to communication are
likely to result in an enhanced resolution of conflict, improved relationships between the
various stakeholders, and in the formation of teams who focus on the shared goal of the best
possible outcome for the patient. Listening and advising in a non judgemental manner is
likely to increase the likelihood of referring hospital staff and retrieval team members asking
questions in relation to optimal patient care. This may well result in a reduction in clinical risk
(26). The retrieval coordination role poses extra communication challenges not faced in the
standard workplace. A large proportion of the communication work is performed on the
telephone. In the normal setting, a substantial amount of communication is achieved by non
verbal means such as eye contact and body posture (27). Factors such as tone of voice, speed
and content of speech and listening become more important when visual cues do not form part
of the interaction. Cultural factors also play a part in effective communication. Issues such as
power distance, the effect of gender, individualism-collectivism and uncertainty avoidance
can vary greatly amongst cultures (28). An awareness of cultural variation can assist the
coordinator when interacting with colleagues and giving advice. A colleague from a culture
with a large power distance may be more reticent to question authority than a colleague from
a low power distance culture. Those from cultures with high uncertainty avoidance may
benefit from more directive advice than those from low uncertainty avoidance cultures. In
general, an assertive communication style which incorporates respect for others and a desire
to help will assist with the communication goals of the retrieval coordination role – those of
obtaining clinical information, giving clinical advice and arranging retrieval where necessary.
Call for help early Calling for help early is of relevance to every member of the retrieval team, including the
retrieval coordinator. There is sometimes resistance to asking for help – at the junior level for
fear of being criticised and at the senior level for fear of being seen to lack knowledge or
capability. The timely involvement of appropriate expertise can impact upon the success of a
retrieval. This may be from the clinical perspective, when the advice needed by a referrer or
retrieval team member lies outside the expertise of the coordinator, or it may be from a
logistical perspective when difficulties arise with arranging a destination hospital. Criteria that
mandate the calling for help have been validated as being useful in the clinical setting in the
form of the MET (medical emergency team) call (31;32). These criteria remove the barriers to
calling for help outlined above. Similarly, Adult Retrieval Victoria Coordinator Guidelines
describe situations that mandate the calling for help, stating that ‘failure to resolve platform or
crew response decisions within a reasonable time period (60 minutes) requires escalation of
the issue to ARV admin-on-call’ or equivalent, and ‘issues that cannot be simply resolved
must be escalated to the Director ARV or the Clinical Advisor ARV urgently’ (6). Delaying
the call for help in this situation can result in a potentially life threatening delay to definitive
care for the patient.
55
Allocate attention wisely There is a recognised tendency when stressed to focus on one particular issue that may lie
within the control of the stressed individual (31). The term given to this is fixation error. The
coordinator who finds themselves responsible for the retrieval of a critically ill individual
weighing 140mg at a distance of 250km from a suitable destination may find themselves
focussing on the difficulties of moving the patient given the weight limitations of fixed wing
(6). A wise allocation of attention may result in the focus changing to providing skilled
personnel to the referring site by the fastest means available, without allowing difficulties
around platform issues to delay provision of the skill set required to the patient. Using all
available information is also relevant to platform and crew selection. The synthesis of
variables such as availability of airports, distance from receiving hospital, availability of
alternate road options eg. HATS (high acuity transport service), CPAV (complex patient
ambulance vehicle) and Emergency car as well as the skill set of the crew (6)– represents a
complex decision making exercise where the best outcome may result from a broad outlook.
Distribute workload Distributing the workload and using all available resources is important to allow the
coordinator to maintain an awareness of the big picture. The appropriate delegation of tasks
and involvement of other team members is a necessary step to maximising situational
awareness. The necessity of distributing the workload has been recognised at an
organisational level, whereby various checklists for different team members have been
developed. This includes the Call Taker Script which defines that information to be gathered
by the RASO. Flow charts detail the process of call taking, and define the point at which the
coordinator begins to gather information from the referring clinician. ‘Anticipation’ provides
the impetus for the creation of checklists, remembering to ‘use all available resources’
provides the prompt to use the checklists. ‘Available resources’ in the retrieval context also
refers to the destination hospitals available to take patients. This includes the option of
transferring patients to the private sector. When using this option, it is important for the
coordinator to be aware of the financial implications for the organisation, and to facilitate
transfer back into the public system at the earliest opportunity for those without adequate
private insurance or DVA (Department of Veterans Affairs) cover. On occasion, an interstate
hospital will also constitute an available resource, and may be used for geographical reasons.
The use of this resource requires communication with all relevant parties by means of a
teleconference to avoid misunderstandings.
Crisis Resource Management principles are integral to the smooth and efficient running of a
retrieval service. Being mindful of the key points, particularly in the areas of communication,
leadership and forward planning can result in improved conflict management, enhanced job
satisfaction and most importantly, patient safety. The job of the Retrieval Coordinator is a
complex one, where application of the key components of Crisis Resource Management can
result in better performance and outcomes in the management of patients with critical and
time critical illness.

High Performance Teams Dawn Chan
High performance teams refer to teams, organisations or groups that are highly focused on
their goals.1
A team can be defined as “a small number of people with complementary skills who are
committed to a common purpose, set of performance goals, and approach for which they hold
themselves mutually accountable.” This definition is the difference between a work group and
a team.2 An effective team should be small enough to be efficient and productive, yet large
enough for collective strength from the diverse skill sets of team members.3 Teams thrive
when given an appropriate amount of autonomy, communication and trust levels are high and
a common goal is shared.4
These high performance teams are also employed in the corporate, military and aviation
industries.
In healthcare, we are no strangers to interdisciplinary co-operation. However, this interaction
is not always efficient. With the continued evolvement of specialised healthcare and a
growing number of patients, the need to develop successful interdisciplinary teams becomes
more apparent as we need to work quicker and more efficiently together. In the retrieval
setting, this is particularly relevant, especially via high performance teams.
Many personnel involved in the retrieval setting possess certain traits. In general, they are
highly skilled and credentialed individuals who possess technical competence, hardiness,
flexibility, commitment and well developed skills in clinical decision-making and critical
thinking. These characteristics aid in the formation of a high performance team environment.5
There are many factors contributing to the success and performance of high performance
teams. In general, the formation of a high performance team requires time for the building of
trust between members and for each member to have a shared understanding of his/her role
and the roles of other members, as well as the overall goal of the team. This allows team
structure to be defined within the team.3 Clinical teams that are temporary and formed rapidly
require an expedited team formation stage and progress rapidly to the performing stage.3 This
reflects the retrieval setting, whereby teams are often put together at the last minute with any
available personnel.
Effective Teams An effective team needs certain members. In our work setting at ARV, the tasked retrieval
team generally comprises of a skilled clinician, an environmental expert and a driver or pilot.
Complex cases can require staffing with two skilled clinicians.6 Clinicians can include a
doctor or MICA paramedic. The environmental expert is a paramedic, either an ALS
paramedic or MICA paramedic. On the HATS platform, this environmental expert is a
specifically trained critical care nurse. The driver on road platforms is generally another
paramedic, thereby providing an extra level of expertise to the team. On rotary wing
platforms, the crewman is trained to assist the MICA paramedic despite not having a medical
background. This team structure is generally replicated for our cases, which facilitates
expedited team formation. Although individuals may not have worked together prior to the
case, the skill sets are reasonably well defined in the above structure, thus allowing a certain
level of trust within the ad hoc team. Individual roles and team goals are already pre-defined
by our skill sets in this setting. As long as members are willing to cooperate on a personal and
professional level, this temporary team can still function as a high performance team. The
bigger team here includes the clinical co-ordinator, flight co-ordinator and
referring/destination hospitals.
58
Common Vocabulary Common vocabulary is a crucial factor for high performance teams. A standard set of generic
knowledge, skills and attitudes allows for effective and concise communication.4 It can reduce
errors due to miscommunication especially when using specialised lingo. This common
vocabulary can also help bind the team and promote trust when working together. In the
retrieval setting, it allows personnel from different backgrounds to work together as we can
all understand the clinical impetus and implications of the case. Team efficacy is improved
when individuals can work independently but yet together to achieve a common goal, thus
making the team larger than the sum of its parts.2 In particular, in the ARV setting, our work
involves transportation of critically ill patients. Doctors trained in critical care specialties and
trained paramedics are required. Referrals made by non-critical care trained staff often do not
convey the true picture, due to this lack of specialised common vocabulary. The common
knowledge of drugs, equipment and procedures allows for overlap and flexibility of roles,
thus improving safety and efficiency of the mission; especially when individuals are able to
pre-empt each other’s actions.
Diverse and complementary skillsets A high performance team comprises of members with diverse yet complementary skills.2 This
allows the team function under a much broader scope, but yet possess enough core strength
with overlapping skill sets to cope with most emergencies. Our team structure of doctor and
paramedics (MICA/ALS) is a good example. Extra skills doctors possess include an overall
assessment of the clinical situation and treatment needs (the big picture), interpretation of test
results, technical skills like invasive line insertions, airway management and invasive pacing,
familiarity with complex patients and most importantly familiarity with the hospital system.
This complements the MICA skill set, which includes familiarity with the transport
environment, expediently transporting and packaging unstable injured patients, airway skills
and familiarity with general advanced life support drugs. The ALS paramedics possess the
same environmental awareness and skill in transportation of sick/injured patients. The pilot
obviously possesses a very different and crucial skill set, but yet has the same environmental
awareness as the paramedics. The clinical co-ordinator is a highly skilled and experienced
critical care doctor, thus providing clinical leadership for the case. The flight co-ordinator
similarly is a highly skilled and experienced paramedic, thus providing situational leadership
for the case.
Collaboration Collaboration is another essential component of high performance team interaction.5 Having
members with the abovementioned complementary skills has limited use if they do not
collaborate whilst on a mission. Team members collectively performing patient assessments,
doing procedures and developing plans allows a clear understanding of the plan, fast and safe
execution of procedures and complete assessment within a shorter time.
To facilitate collaboration, mutual trust and respect is vital.2,3,5 The differing backgrounds of
teammates can generate differing opinions of boundaries and hierarchies, which can be
detrimental to the health of the team. It is very important to respect the skills and competence
of our colleagues. Doctors are often used to being the clinical team leader in the hospital
environment. MICA paramedics have similar experiences to us of being the clinical team
leader in their environment. An experienced MICA paramedic and doctor can often have very
similar competencies. In our retrieval setting, it is important to be mindful of this fact. Either
party depending on the clinical situation of the case can undertake the role of team leader.
This mutual respect and trust will allow collaboration i.e. parallel assessments and treatment
of the patient, thus improving efficacy and performance. For example, I am comfortable
leaving the paramedic to assess the patient whilst I get handover from the referring team.
These separate arms of action put together will generate a complete picture of the patient’s
status in a much shorter timeframe.

Task specific and flexible leadership High performance teams function best when leadership is task specific and flexible.5 The
profession with the needed expertise will lead the team at the time, allowing shared and
transient leadership. This rings true whilst transporting a patient. Medical staff can have
clinical leadership when dealing with the patient’s assessment and treatment. However, we
should defer to the paramedics who are the environmental experts in matters of packaging and
moving the patient. They have far more experience than we do with regards to the
performance of equipment whilst on different platforms, the likelihood of particular
complications whilst enroute and adapting to the platform environment when treating the
patient. This model ensures that the leader is always the most experienced person for the role,
which undoubtedly will improve performance of the team. To still allow for accountability
and administrative control5, the clinical co-ordinator and flight co-ordinator will still be the
overall team leaders in the respective areas mentioned above.
Common Specific Goals To function efficiently as a unit, the team needs to have a common goal.2-4 Having a bunch of
highly skilled personnel going off on their own tangents is likely to be counterproductive. It is
crucial to the success of a task that the plan is clearly understood by all team members, as the
actions and efforts of the individuals need to be towards achieving this common goal. For the
retrieval team, all staff need to understand the clinical condition and treatment plan for the
patient prior to any movement of the patient. In the event of deterioration or emergency
enroute, there is generally no time for discussion of the plan and or objections of the plan if
any. These issues need to be sorted out prior to patient movement.
Team autonomy Team autonomy4 is yet another factor that can boost performance. Giving an appropriate
amount of autonomy to the team can improve team morale and work satisfaction. This is
actually unavoidable in the retrieval setting. The retrieval team is often responsible for
making the clinical decisions for the mission. This is due partly to the expertise of the team
and partly to the nature of the work. Information received pre-mission is often sketchy and
possibly inaccurate. There is often also ongoing deterioration of the patient whilst awaiting
arrival of the retrieval team. Thus we are unable to formulate a definitive plan pre-mission.
Options for potential scenarios can be discussed in a pre-mission briefing. The complex
nature of many of our referrals also make it difficult for the clinical co-ordinator, who is
receiving information over the phone, to make definitive decisions and plans for the retrieval
team as subtle insinuations might be missed. In addition, the retrieval team is designed and
tasked as a highly skilled team of clinicians, who are trained to assess and treat this category
of patients. It would be logical to use this resource as it was designed, by allowing them to
assess and treat the patient based on their clinical judgement. This also touches on mutual
respect and trust accorded by the team leader (co-ordinator) to his or her retrieval team.
However, there still needs to be an overlying authority, who would be the co-ordinator in this
situation. This is to ensure that when various teams intersect, their interaction is not hampered
by each team’s autonomy.
Rapidly forming teams All the abovementioned factors are important in building a high performance team. However,
they are especially true for temporary teams, which have to be formed rapidly. The ad hoc
nature of our retrieval teams and work requires a higher level of commitment, trust and
respect of each other’s abilities and collaboration. The unpredictability of the work calls for a
certain amount of team autonomy. It is impossible to have a fixed plan until the team has
assessed the patient for themselves and considered the transport and clinical risks. It is a
valued trait for the team to be flexible and adaptable to the varied environment. There are
often unpredictable factors like weather, equipment failure and patient complications that can
60
turn a routine case into a very complicated and difficult one. The challenges need to be
overcome promptly as they arise. High performance teams are generally static and moulded
over time to allow members to work together, assess each other, establish roles and learn to
trust each member of the team. It is a credit to all individual personnel involved that a
successful dynamic high performance team can be achieved in our retrieval setting. I believe
this is possible due to experience gained from our respective work and training, in the areas of
adaptability, interpersonal skills and teamwork.

ARV Coordinator Guidelines Activation of Retrieval Early activation is imperative to optimize system efficiency and responsiveness. Activation
may occur prior to the known availability of a destination (receiving) hospital.
Activation includes early communication with all resources / platforms: AAV, AV, Regional
AV.
Aviation Resources The allocation of aviation resources is not the responsibility of the ARV Coordinator, but
rests with AAV. Input can be provided, but it should be recognized that AAV may have
multiple competing requirements, including primary response.
Aviation resources may not be available due to: weather conditions, pilot duty restrictions,
aircraft maintenance or performance issues, or other tasking.
AAV, regional AV and the coordinator need to be involved in discussion related to the
transfer of patients where the use of air resources is of marginal benefit or not available in a
timely manner.
Where aviation platforms are not available, the ARV coordinator must facilitate alternate
retrieval arrangements for the patient in consultation with the AV Clinician. This may include
consideration of road platforms (such as HATS, CPAV, Emerg car – local or metro), and
various options of retrieval team depending on availability and required skill mix. Failure to
resolve response decisions within a reasonable time period (60 minutes) requires escalation of
the issue to ARV admin-on-call, AAV manager, AV DTM, regional duty manager or others
as appropriate.
For fixed wing transfers, a patient weight limit of 120kg exists due to engineering limitations
around patient loading and aircraft floor load capacity.
For rotary transfers, patient weight limits are generally those of the stretcher (approximately
160-200kg) however the practical limitations of size and manual handling are usually reached
by patients at much lower weights than this. Any patient >120kg must specifically be
discussed with the flight coordinator to determine appropriateness for RW transfer.
Blood and Blood Products Urgent supplies of blood and blood products may be sourced from the Red Cross Blood Bank
(Contact: 03 9694 0200). Items will be delivered by RCBB by courier or taxi, or may be
collected by emergency vehicles (dispatched via the duty manager or clinician). Cold storage
bags are available on site for transporting products. Blood dispensed in this way should
remain with the patient, as should all completed records of administration.
It is preferable to source blood and blood products from the referring site laboratory where
possible.
A current project is expected to see availability of limited blood stocks on-site at Essendon in
early 2011.
Call Processes The coordinator will at all times communicate in a professional manner, respectful of the
circumstance of the referrer, the stressful nature of critical incidents, and the role of ARV and
AV in the State Health System.
The coordinator must remain mindful of the need for optimal communication styles, and of
communication strategies that may be applied to ensure complete and clear communication of
relevant clinical and risk related matters with the referrer.
• Always allow the referrer to complete statements – do not complete for them or “put
words in their mouths”
63
•
Reflective checking is valuable: “Thank you Dr X, I understand from your statement that
the patient is ….. – is that correct?”
• Ask direct risk related questions: “Dr, Do you perceive any major risks or hazards in the
transfer of this patient?”
• Leave the door open for further communication: “If you think of anything else that may
be important or that arises after this call, please phone me back”
Consideration will be given to early inclusion of other parties in the conference call (e.g.
AAV Flight Coordinator, Regional AV ops centre, receiving unit or Trauma Service, Duty
Retrieval Physician, Flight MICA/Paramedic)
The coordinator will determine whether the request is for one or more of:
• Request for assistance with accessing a critical care bed or time critical intervention
• Request for assistance with inter hospital transfer
• Clinical Advice
The coordinator will assess the clinical and situational information provided, and formulate a
plan in consultation with the referring party. Decision making in such circumstances is often
complex.
The coordinator will provide clinical and logistic advice as required to the referrer. This
advice may be to the requesting hospital, Retrieval Physician or paramedic escort. The
coordinator may need to seek assistance in some areas of clinical medicine. Specialists in the
receiving hospital should also be considered as sources of advice.
Where a Critical Care bed is required, the ARV Call Taker will confirm availability and
notify the coordinator immediately (and facilitate telephone connection with that unit).
Continuity and Handover At the end of the shift, the Coordinator will handover to the Coordinator rostered for the next
shift.
All cases which are incomplete or in progress must be communicated to the incoming staff.
This ensures that the active coordinator is aware of the location of all ARV retrieval staff and
teams. This is relevant from the perspective of potential mission diversion or re-prioritisation,
delays and risk management; in addition an active retrieval team may seek assistance from the
current coordinator who must be aware of the mission, its complexities, plan, destination etc.
Any cases which are believed to be completed but where significant potential exists for rereferral on the subsequent shift should be communicated.
All cases where significant outcome risk, organizational risk, media attention or major public
interest exist should be handed over to the next coordinator so they are aware of cases they
may receive enquiry about (such cases should also be communicated to the ARV office).
Coordinator Contact and Availability The Coordinator will be contacted by the ARV RASO, by either phone or pager.
The Coordinator will carry both mobile phone and pager while rostered.
The Coordinator will be available to discuss the case with the requesting party within 15
minutes.
All phone contact will occur via 1300 368 661 to enable voice logging for quality assurance
processes.
Calls will be received from across the entire State – regional retrieval services defer to ARV
metro as the central coordination office.
The ARV RASO will facilitate conference calls with ARV, Coordinator, Referrer or others as
required.
Crew Briefing For all retrieval missions, the coordinator will discuss the case and clinical details with the
responding crew (doctor or paramedic).
MICA road crew transfers within the metropolitan area should be considered as a retrieval
option only when the clinical situation requires an emergency level of response (re time
criticality), or the setting is analogous to a primary response. In other circumstances, it is
64
more appropriate to task ARV staff (according to hospital type) or to negotiate transfer by the
referring hospital.
65
66
Crew Mix The coordinator will determine the Crew-mix that has the most appropriate skill set for a
specific clinical scenario. Principle factors involved in this decision will be clinical
complexity and patient instability (actual and potential).
High Risk Patients
• A significant group of high risk patients are those who have a potential need for
airway intervention and ventilator support during a mission. This includes for
example patients with significant intracranial pathology. Such patients may be stable
at the time of presentation but have a significant risk of rapid deterioration (e.g.
conscious patients with subarachnoid haemorrhage). Retrieval of such patients should
be performed by crews that have capacity to provide airway support (MICA or
Doctor). If the patient is unstable or has existing significant neurological signs, a two
person crew must always be used, to ensure risk minimization in airway intervention
procedures and ongoing management of the patient in flight / transit.
• Current crew options include ARV retrieval physician, source hospital medical or
nursing staff, MICA Flight Paramedic, MICA Paramedic, Ambulance or Flight
Paramedic and combinations of these.
Critical Care Patients
• Normal crew recommendation for such patients (consistent with national guidelines
and industry governance norms) is two clinical staff. At least one must be critical care
trained (e.g. MICA, FMP, RetrDr) in all cases, and in some cases two critical care
trained staff are appropriate (e.g. very long jobs or very unstable/complex jobs).
• Whilst this is a guide and a recommendation (and in many senses ideal), it is also
something that needs to be considered on a per case basis – considering alternates,
most efficient response options, concurrent workload etc. There will be times that
expediting a single-clinical-crewed critical care retrieval is a better option (or the only
option) depending on resource availability and logistics.
Crew Mix Flexibility
• Desired crew mix is dependent on case complexity and actual or potential instability,
and on matching crew skill set with known or anticipated clinical need:
• In some circumstances, the preferred crew option may not be available, eg no
retrieval physician available, no MFP available, time criticality may preclude waiting
for RP to arrive at airport if response time is prolonged.
• In some circumstances, the initially tasked crew officer may have reservations about
their ability to comprehensively manage the patient. In these circumstances, the crew
mix should be strengthened by addition or replacement with another crew member.
Cardiac Pacing
A retrieval physician is required for (interhospital) retrieval of the following patient types:
patients requiring Cardiac Pacing (Transvenous or Transcutaneous)
patients with a high likelihood of requiring pacing - principally this will be patients receiving
Chronotropic Infusions (Isoprenaline / Adrenaline) for bradycardia.
These are circumstances where TCP may be a life-saving intervention. Currently MICA flight
paramedics are not credentialed to use the Zoll TCP.
The Zoll defib/pacer, and the external pacing box need to be included in the kit for these
missions. Transvenous wires are not currently part of the ARV standard equipment, will most
often be inserted at the referring hospital if required, and their insertion would require
individual physician credentialing. In a situation where a small hospital does not have the
resource or capability to initially stabilise a patient in this clinical scenario, coordinators
should consider expedited emergency MICA transfer (road or air as appropriate) to a centre
with capacity to provide resuscitation at least - rather than a delay for retrieval response. [This
is analogous to the patient with uncontrollable haemorrhage in a small hospital, unable to
provide intervention].

Defined Patient Transfers This guideline relates to the DHS Interim Critical Care Capacity Guideline.
(http://www.health.vic.gov.au/criticalcare/ccguide08.pdf)
Should there be need for a patient to access an ICU bed in the setting of no appropriate ICU
bed being declared available on the Victorian Critical Care Access Website, a defined transfer
may be authorised by the Director of ARV or delegate.
This process applies for patients needing retrieval to a site where definitive care can be
provided, and assumes that such care is not available at the point of referral. The process
assumes that the patient will gain a higher level of care through this transfer. A patient should
not be transferred under this policy if all that is achieved is the same standard of care in
another setting e.g. transfer of an intubated overdose patient from ED in a metro centre with
ICU consultation to the ED of a tertiary centre.
In this circumstance, the ARV admin on call (Director or delegate) will contact an appropriate
destination hospital, speak with the Executive Officer on duty, and authorize transfer of the
patient. The ARV coordinator will subsequently liaise with referring and receiving clinical
staff.
An analogous process is in place for patients with time urgent neurosurgical emergencies for
whom no bed is currently available.
Decisions about which hospital is to receive the patient will be made after consideration of:
• Capability and capacity of the referring health service.
• Nature of the surgical/other intervention required by the patient.
• Capability and capacity of the potential receiving health service.
• Nature of the clinical condition.
• Degree of clinical urgency.
• Known or anticipated critical care system demands.
• Normal referral and historical clinical relationship patterns.
• Geographical proximity.
• Needs and consideration of the patient’s family.
Documentation of Coordination All requests for assistance will be documented and included in the ARV database.
The standard Coordinator Data Form will form the base level of data and information capture
required.
Completed Coordinator Data Forms will be faxed or e-mailed to the ARV office within the
next working day.
Drug Stocks : rare items Where urgent need occurs for drugs that are not normally carried by ARV, a process has been
established to source items from the Alfred Hospital. The ARV coordinator should discuss the
request with the duty pharmacist at the Alfred, and make arrangements for collection of the
item.
Payment is managed via the ARV office on the next business day; the coordinator is required
to advise the ARV Business Manager of such cases.
ECMO Patients with ECMO. Alfred Hospital and RCH provide transport ECMO services
collaboratively with AV. ARV are responsible for logistics and platform coordination, and the
receiving hospital for staff and equipment. An MOU exists between AV and these hospitals
outlining these responsibilities and obligations. ARV contact for adult ECMO is the Alfred
ICU.
Key concepts include:
Optimal communication between all parties involved in retrieval work is essential. To this
end, ARV uses teleconferencing and videoconferencing technologies extensively. (All calls
to and from ARV are recorded for quality purposes)
69
Where patients are referred to ARV regarding potential ECMO transfer/commencement, or
where they meet general ECMO inclusion criteria, the ARV coordinator will initiate a
teleconference involving the Alfred Hospital ICU consultant.
Where the Alfred hospital receives direct referral of patients for ?ECMO transfer, the ICU
consultant will contact ARV to ensure commencement of a teleconference involving the ARV
coordinator from the outset.
All ECMO retrieval staff will be fully credentialed.
Decisions will be made jointly and collaboratively. Issues that cannot be resolved will be
escalated to the ARV and Alfred ICU directors (or delegate)
Prior to any ECMO mission, the ARV coordinator will discuss the case with the ARV director
or delegate, and subsequently convene a “Summary Teleconference”. This will be attended by
all involved clinical and logistics parties or the case must not proceed. In this
teleconference, the plan including contingencies will be discussed and agreed.
During ECMO transfers:
The ARV coordinator is the clinical ‘control point’ for all retrievals. They are responsible for
defining time criticality of a retrieval case, and for overall coordination of crewing, logistics
and resource.
All case communication will occur through the ARV RASO / coordination office.
All transport coordination will be provided by ARV utilising AV transport platforms.
Urgency of outbound legs will be discussed with the ARV coordinator who will coordinate
platform responses via AAV, ERTCOM or NETCOM.
Standard crewing will be: Paramedic, ARV retrieval physician, Alfred Team (Intensivist(s),
+/-ICU RN)
Clinical leadership will be provided by the senior intensivist
Operational leadership and environmental guidance will be provided by the ARV retrieval
physician
Patient movements and transfers will be minimized, and will occur in well-lit, protected
environments (e.g. a hangar rather than open tarmac).
During air missions, the pilot is responsible for the overall safety and management of
logistics. In flight the pilot is in control of all resources, and is responsible for all decisions in
relation to the aircraft, flight path, safe altitude etc.
Transfers of up to 4 hours travel time are normally performed by road platform although air
transport to the referring hospital (for response rapidity) may be appropriate. All ECMO
transfers must be discussed with ARV Director or delegate.
70
71
Hospitals Reference Database The hospitals reference database provides an up to date profile of the referring and receiving
hospitals in Victoria, including their classifications, facilities, investigative lab capability etc,
and general recommendations regarding transport options.
It is available at: G:\Emergency Operations\ARV\ARV DataBase\Hospital Reference.
IABP For IABP, some referring hospitals have historically provided IABP equipment and staff,
ARV organizing logistics and additional staff if required. In general the preferred
arrangement is for ARV to coordinate IABP transfer with pump and technical support from
Perfusion Services Ltd, with whom ARV has an MOU and clearly developed systems and
standards designed for the transport environment. Contact Perfusion Services via: 95856011,
pager 96253184 or 1800641581 (James McMillan).
Transfers of up to 4 hours travel time are normally performed by road platform although air
transport to the referring hospital (for response rapidity) may be appropriate. Interstate or air
IABP transfers must be discussed with ARV Director or delegate.
Interstate Retrieval Procedures Adult Retrieval Victoria (ARV) is responsible for retrieval services in Victoria. From time to
time situations occur where a patient in Victoria requires retrieval to an interstate destination,
or where ARV is required to retrieve a patient from interstate to a Victorian hospital.
Principles
In these circumstances there are several principles that must be followed:
The clinical care of the patient is the primary consideration, and decisions made must not
compromise patient care or outcomes. NB: The clinical care of the patient may be influenced
72
by numerous factors, including (time) availability of in-state retrieval services, weather,
platform availability, platform logistics e.g. weight limits.
The usual domicile of the patient and relevant relationships they have with clinical services
are significant. The patient’s wishes must be considered, for example a patient request to be
close to supportive family may mean a cross border transfer for someone living close to a
State border.
Coordination responsibility
Responsibility for coordination of a retrieval case fundamentally rests with the State in which
the referral hospital is located.
Exceptions to this are:
Patients located in southern NSW including Albury, Finley, Deneliquin and Barham, where
long standing referral and secondary care links exist into Victoria.
Some patients of Mildura Base Hospital - whose primary social support links or relevant
immediate past clinical care links are in Adelaide (assumes Adelaide destination hospital).
Interstate communication
Where ARV is coordinating a proposed patient retrieval from a Victorian referral hospital to
an interstate destination hospital, a teleconference must occur between the ARV Critical Care
Coordinator (CCC), the interstate Retrieval Services Coordinator (Adult), and any additional
stakeholder (receiving and referring clinicians, retrieval team members, aviation service
providers etc).
Retrieval to an interstate destination
Patients will normally be retrieved by the receiving State retrieval service, however situations
may occur where the referring State transports a patient interstate due to clinical platform
logistics or availability e.g. ARV retrieves a patient from Mildura to Adelaide. ARV cases,
with a planned interstate destination utilising ARV staff and AV assets, must be escalated to
the ARV Director or delegate prior to commencement of missions.

Issues Incidents or Problems Issues or problems which may arise must be handled in a collegiate and professional manner,
with the patient well-being and clinical outcome the over-riding consideration. Issues that
cannot be simply resolved must be escalated to the Director ARV or the Clinical Advisor
ARV urgently.
Regional AV logistics or other issues may be escalated via the Regional Clinician to the
Regional Manager as required.
Any issue or event which exposes the service or a patient to risk or which results in harm to
staff, public or patient must be reported to the ARV Director and via the ARV Incident
Reporting framework.
At present these would be (by default):
• patient death in our care
• staff injury
• near miss / event with potential for patient harm (level 2 variation)
• actual patient harm due to error (level 1 variation)
• other critical risk (logistic or clinical)
Morbid Obesity Patients with morbid obesity (arbitrarily defined as: weight over 140kg, or BMI over 45) who
require mechanical ventilation for management of pulmonary pathology, or who require
mechanical ventilation and have other significant co morbidity, should routinely be crewed by
ARV doctor and MICA. These patients must be considered clinically very complex and at
significant risk for transfer.
73
It is not possible to lift patients over 120kg into the current fixed wing aircraft due to
loading equipment limitations. This does not relate to rotary wing aircraft where patients over
120kg may be considered for transport on a case by case basis.
Night Transfers Transfer must never be delayed in a time critical patient. (This includes patients with
significant risk of deterioration during the time delay).
Non Time Critical aviation transfers should not occur after midnight (air crew fatigue and
human factors issues)
It is imperative that the skill set and capacity to provide ongoing care at the referral site is
factored in any decision to delay a transfer.
All cases where transfer at night is delayed will be specifically audited.
Time Critical: In respect of Retrieval Transfer – A patient is considered time critical if the
patient has a clinical condition which presents an immediate threat to life, limb, cognition or
future quality of life, and
• Delay in definitive treatment will significantly increase that outcome risk, and
• Definitive management of that condition or threat is likely to be achieved by urgent
transfer to another hospital, or
• Management of that condition definitively, or for a prolonged interim period, is beyond
the resource capacity or clinical skill capacity of the current provider (or would result in
unacceptable resource drain and exposure of other patients to risk).
Palliation & Non­Transfer Some patients referred for transfer are critically unwell with illness which is inevitably
terminal. The coordinator will consider such requests from the perspective of clinical
appropriateness, and psychosocial impacts. After considering the clinical scenario, including
where the patient currently is and what level of care can be provided, in some cases, it may be
better practice for the patient to remain where they are, and to die in their own community in
the presence of family and friends. This may be preferable to retrieval to a distant hospital for
futile care.
Situations arise where a retrieval physician may also make such a conclusion after assessment
of the patient – these situations must be discussed with the coordinator.
Paramedic Consultation Several of the AV Clinical Practice Guidelines require consultation between Flight MICA
Paramedics prior to specific interventions, and authorization by the ARV coordinator. These
include:
• Administration of ONeg blood,
• Use of NorAdrenaline in doses exceeding 25 mic/min
In such cases the coordinator must make an assessment of the case and provide authorization
and / or other clinical advice as is appropriate.
Familiarity with AV paramedic CPG’s and the skill set of paramedics is essential to this role
(and the provision of advice to the AV Clinician or crews). See: “paramedic skillsets” in this
manual or the AV CPGs at: CPG Link

ndards%20%20Improvement/Clinical%20Practice%20Guidelines%20%28CPG%29
Peak Workload Strategy ARV workload by its nature is variable in intensity and volume. Under normal circumstances,
the current systems cope with standard loads however there are peaks of activity which can at
times be sustained (e.g. in winter). In such situations it is important that Coordinators and
RASO’s identify critical workload volumes and identify strategies to manage this load. The
advised process is as illustrated in the table below.
74
In all cases of peaking workload, the above strategies should be implemented at the earliest
opportunity and continued informed communication with the ARV Admin on call should be
maintained, either by phone or email.

Perinatal Emergency Retrievals The Perinatal Emergency Referral Service (PERS) is a state-wide service providing maternity
care providers in Victoria with a coordinated and timely safe approach for;
• Providing access to optimal expert clinical advice about perinatal emergencies.
• Providing access to obstetric and neonatal resource information.
• Facilitating perinatal emergency transfers to appropriate facilities when required.
In cases where there is likely rapid deterioration in maternal condition without specialist
intervention, such as occurs with major post-partum haemorrhage, uterine
rupture, or acute respiratory failure, or where the mother is or is likely to become critical,
PERS will refer case coordination responsibility and management of the mother to ARV.
In such cases:
The PERS consultant will contact the ARV critical care coordinator and provide a handover
of the clinical status.
Both consultants will discuss the priorities and clinical needs of the case (including but not
limited to):
o Pregnancy specific care needs for the mother
75
o General care requirements of the mother
o The type of preferred destination unit for the mother
o Neonatal care considerations (involve NETS if required)
ARV will coordinate an appropriate crew response for the case
ARV will coordinate appropriate transport for the patient via relevant AV Operations Centres
and AAV where appropriate
ARV will access an appropriate critical care bed for the patient (at a centre which provides
obstetric care normally)
The PERS consultant will remain aware of the case and provide consultation and input via
intermittent briefings from the ARV coordinator, or through involvement in teleconferences
The outcome of the case and / or transfer will be communicated to PERS by ARV.

There are several modifying factors in platform selection:
1. Platform activation time
2. Return destination
3. Crew activation time
4. Secondary ground/air transfer times
5. Clinical Issues e.g. equipment and space needs
Failure to resolve platform or crew response decisions within a reasonable time period (60
minutes) requires escalation of the issue to ARV admin-on-call, AAV manager, AV DTM,
regional duty manager or others as appropriate.
Road Platforms
76
The current options for road transport platforms include – emergency ambulance, CPAV,
HATS, non-emerg vehicle. Due to current staffing and crewing structures the standard
approach to road vehicle choice is as follows:
HATS (with driver + Crit Care Nurse crew) is preferred option during periods of availability,
and if response time is appropriate, unless
ARV Coordinator contacts HATS in the first instance as this is the preferred resource for
ARV retrievals
If HATS is not available the ARV Coordinator contacts the Clinician
In consultation with the ARV Coordinator the Clinician will provide the most appropriate
resource to accomplish the retrieval. In most cases this will be an AGP with at least one ALS
qualified paramedic aboard
If the ARV Coordinator determines that the retrieval requires MICA skill sets to assist the
retrieval physician (uncommon), the Clinician will organize a CSO/SRU to accompany or a
MICA vehicle to do the transfer
The Clinician may consider the use of a CPAV or Netcomm vehicle if they are able to
resource either unit with an ALS qualified or MICA paramedic
If required, the ARV Coordinator can liaise with the Clinician to determine clinical
requirements prior to contacting the Clinician to organize the retrieval
Activation of HATS is performed via Coordinator contacting NPT (private ambulance
service) on 1300 628728 (The RASO will fax a booking form to Netcom also).
Prioritisation of Tasks In some cases, requests for assistance finding a bed or transferring a patient come before all
relevant investigations are available. This information may be necessary to determine
appropriate bed, or of need for transfer, eg CT head, troponin levels. If clinically appropriate,
some decisions and actions can be deferred until that information is available. In other
circumstances, decisions need to be made with incomplete information. Some health services
are unable to provide what some would consider basic investigations (eg blood gases)
The coordinator will determine what are the highest priority patient factors in facilitating
bed access.
• Does the patient require a time critical intervention (eg hot angiogram, neurosurgery,
ruptured AA)? This may be a more important consideration than whether an ICU bed is
immediately available for the patient.
• For Cardiology patients: Do they (or are likely to) require access to (hot) angiography or
monitoring?
• For ICU: Do they require tertiary level care? Do they (or are they likely to) require access
to specialized services (eg dialysis, thoracic surgery)
• For drug overdose patients: There is likely to be a need for psychiatry services after ICU
discharge.
For patients primarily requiring an urgent intervention, this should not be delayed while
finding and ICU / CCU bed. If the intervention can be done in a hospital with a suitable bed,
this will reduce the need for secondary transfer.
Receiving Hospital The coordinator will contact appropriate units based on the above. Initial requests should go
to the lowest level hospitals able to deal with the current (and likely) clinical situation. This
will ensure beds may be available for future more complex patients who may not be clinically
suitable for the less complex hospital. For example, admitting an elderly, haemodynamically
stable NSTEMI to a tertiary hospital rather than an urban ICU, may impact on ability to
manage a (potential) young patient with STEMI and ongoing pain despite thrombolysis.
Geographic factors should be considered, because of impact on family and ambulance
resources. This should involve consideration of regional base hospitals as appropriate.
If the requesting hospital has easy helipad access, and the patient is suitable, consideration
may be given to metro hospitals with better helipad access – this increases efficiency of the
transfer process and resource use and is of particular relevance in trauma patients.

Outside the above hours, each regional retrieval centre will, on request, provide advice and
input into retrieval activity, and each region has a designated contact person for discussion of
specific issues or requests that are outside of the usual agreed operating framework. (ARV
office will facilitate contact).
Retrieval Physician Tasking Retrieval missions will be allocated to the most appropriate RP responder according to
required skillset, physician location and mission activation urgency i.e. particular staff with
specialised skills may be selected for individual missions with known special clinical
challenges.
Where clinical acuity indicates a need for medical crew, and there is no specific need for
consultant level skillset, responding an (on site) consultant may remain an option for the
coordinator. It is important that consultant grade staff remain familiar with routine mission
activities, and be tasked to a range of mission types – both ‘routine’ and highest acuity. This
applies to both air and road missions.
Tasking decisions towards the ‘end of shift’ need to consider both rostered time of shift end
and clinician fatigue. It may be appropriate to delay some missions pending commencement
of a subsequent shift.
Registrars will be assessed early in their rotation to ARV and a decision made re solo
missions, and the level of mission acuity that may be appropriate for them at particular times.
Staff Welfare The nature of retrieval and coordination work can be stressful and difficult. Ambulance
Victoria offers all staff access to peer support and counselling services. These may be
accessed by individuals or via ARV management
Peer Support: contact via Corporate Paging (for duty peer support officer) 9483 8009;
Phone: 0419 002 956 Email: peer.support@mas.vic.gov.au
Counselling Service: Ms Heather Bancroft, VACCU
Phone: 9654 4144 Email: clinical.director@vaccu.com.au
Tarmac Handovers Are generally inappropriate, and patients should be retrieved from a hospital setting. This
allows for controlled handover, assessment of the patient, checking of all equipment,
connections, placements etc. All tarmac handovers will be considered a variation and audited.
(Exceptions may exist e.g. an uncomplicated AMI being transferred urgently for PCI – in
such a case the risks associated with tarmac handover are low, and the time benefit may be
great)
Trauma Calls ARV facilitates the Statewide Trauma Advice and Referral System. Previously a dedicated
line (1800 700 001) was used to activate the Trauma System. Now all trauma calls utilize the
ARV 1300 368661 number. ARV RASO staff will answer the call.
Paediatric calls will be immediately transferred to the RCH
78
Adult calls will be transferred to the requested trauma service
The Critical Care Coordinator will be conferenced into this call and may offer advice in
regard to patient transfer or retrieval.
All calls will be recorded as per standard ARV processes
The Coordinator may depart calls at their discretion if content is not of relevance to transfer or
retrieval (after informing other parties of this departure).
State Trauma System
(see also: http://www.health.vic.gov.au/trauma/guidelines/index.htm)
Adult Patients
Ambulance services should triage adult major trauma patients and suspected adult major
trauma patients directly to an adult Major Trauma Service (The Alfred and the Royal
Melbourne Hospital), when the travel time is less than 30 minutes.
If a Major Trauma Service is not within 30 minutes travel time, then the patient should be
triaged to the next highest-level trauma service within 30-minute travel time, from the
accident site.
Specialist Trauma Triage and Transfer
Hospitals with neurosurgical specialities should manage neurotrauma patients requiring
critical care support.
Major trauma including spinal trauma should initially be triaged to a Major Trauma Service.
Early consultation by each treating hospital with the Victorian Spinal Cord Unit at the Austin
Hospital is essential to optimise patient outcomes.
Discrete spinal cord injured patients over 16yrs of age, in the absence of other indicators of
major trauma, should be triaged to Austin Health’s, Victorian Spinal Cord Service by
telephoning (03) 9496 5000 and asking for Spinal Unit Acute Registrar.
Multiple trauma, incorporating the need for microsurgery, should be referred and transferred
to a Major Trauma Service. St Vincent’s Hospital also have capacity as leaders to manage
injuries requiring microsurgery.
Neurosurgical triage and transfer guidelines for major trauma still apply in rural areas, even
where a neurosurgical specialist practises locally, as the management of these patients
requires all the appropriate and agreed service supports of a Major Trauma Service.
Elderly patients with isolated neurotrauma may be transferred to a general neurosurgical unit.
Pregnant Trauma patients are transferred to the RMH where protocols are in place for shared
care with the RWH.
Major Trauma Triage Guidelines Require:
Pre-hospital major trauma to be identified according to specified physiological and
anatomical criteria.
Triage to a Major Trauma Service where a major trauma patient is less than 30 minutes
transport time from a Major Trauma Service.
Triage to the highest designated trauma service accessible in 30 minutes where a major
trauma patient is more than 30 minutes transport time from a Major Trauma Service.
Triage to a designated trauma service accessible in the least amount of time in isolated rural
areas that are more than 30 minutes from any trauma service.
Where a major trauma patient appears to be in an immediately life-threatening situation
during transport, the patient be diverted to the nearest designated trauma service for
stabilisation, with subsequent transport to a Major Trauma Service at the earliest appropriate
time.
Where a patient is triaged initially to a non-Major Trauma Service for stabilisation, early
liaison with the Major Trauma Service should occur via the Trauma Advice and Referral
telephone line 1800 700 001, which is answered by ARV calltakers. Consideration of
appropriate medical retrieval or interhospital transfer to a Major Trauma Service can then
occur from the initial call.
Unable to respond In any situation where timely retrieval response is not able to be provided (due to crewing or
weather, or other factors, this decision must be discussed with the referral agency, and every
79
effort made to assist in resolving the problem or resource gap. Review of the status of weather
or logistics within an agreed timeframe should occur, and further communication be
undertaken if necessary.
There are circumstances where such delays or impediments indicate that a preferred option
(only viable option) for a patient may be a ‘mercy dash’ with any available AV crew and
referring doctor to move the patient to the nearest site capable of necessary resuscitation.
AV provides a work instruction to facilitate this which essentially requires close collaboration
and planning between referrer, AV Clinician, AV crews, and ARV coordinator.
Uninsured Patients & Private Hospitals In general, uninsured patients should be preferentially placed in the public system, and
insured (including DVA) into the private system. Exceptions include trauma (either TAC or
Workcover) who should be transferred into the trauma system, and those requiring time
critical interventions which may be difficult to facilitate in the private system (eg urgent
craniotomy)
ARV is responsible for all costs incurred when moving a public patient from a regional/rural
hospital which has no ICU Unit (or patients from Werribee Mercy, RWH and RVEEH) into a
private bed. This does not apply to any metro/regional/rural hospital which has any ICU
capability. All other factors being equal, preference should be given to placing rural patients
into the public system.
In all such circumstances, it remains the responsibility of ARV to monitor the status of
patients on a daily basis, and to assist in transfer of the patient to a public hospital at the
earliest clinically appropriate time. It is the responsibility of the referring health service to
make available an appropriate bed for the patient to be returned to as soon as possible.
Regarding uninsured patients who self‐present to a private hospital ED and require
critical care admission (ICU, CCU, HDU): If the patient elects to be a public patient (as
opposed to agreeing to self-fund private care), then the hospital is responsible for all charges
for the first 24 hours of care, after contacting ARV to request patient transfer. This 24-hour
period allows ARV to find an appropriate public hospital, where it is clinically appropriate to
transfer the patient. ARV is responsible for payments after the first 24 hours if the patient
remains in the private hospital.
Videoconferencing Capability Guidelines for Virtual Trauma and Critical Care Unit (ViTCCU) and GRAHnet calls
Background
ViTCCU and GRAHnet provide broadband-based clinical support for hospitals in the
Loddon-Mallee and Grampians Healthcare Networks. Regional hospitals (attached list) are
able to link to ARV as well as some metro hospitals (Alfred, Austin, St.Vincents and The
Royal Children’s) from mobile video-conferencing units. The system has been operational
since 2009 but has been relatively underutilised due to lack of clinician engagement at both
sending and receiving sites.
ARV’s role is basically as a hub for clinical advice as well as the opportunity to link with
tertiary hospitals for referral / clinical advice as needed. Having real-time vision of the patient
as well as the ability to view x-rays, CT scans live makes patient assessment and retrieval
planning significantly easier. If this pilot project is successful, then there is the potential for
this technology to be rolled out statewide.
First and most importantly, Clinician engagement – there is a natural reluctance for clinicians
to engage with new technology. Encouraging their use of this technology – and making it a
‘user friendly’ experience will help reinforce its use in the future.
ARV also have a ‘forcing’ opportunity – that is by mandating its use when receiving calls for
advice / retrieval, we can ‘embed’ it as part of clinicians’ practice.
Guidelines for using ViTCCU
ViTCCU should always be used for clinical advice / retrieval calls from appropriately
equipped hospitals – please document ViTCCU use on the call sheet. If a clinician calls from
80
one of the hospital on the list, they may need to be prompted to turn the system on and
position it – the unit may not always be in the calling unit and may need to the moved to the
patient. Simple instructions to facilitate this are available on the CC desk (Grampians yellow
folder, Loddon-Mallee white folder).
We have encouraged regional hospitals to ‘overuse’ the system initially to improve
familiarity.
Please be positive and welcome calls for advice, even if you don’t think they are core ARV
business – positive reinforcement of clinician engagement, will significantly improve longer
term uptake
Ultimately CT scans and other radiology will be available via a CERNA application – this is
still in development – for the time being, the resolution of the system is good enough to view
films on a light box or computer screen.
It is possible to have a three way teleconference involving receiving hospitals – the logistics
of this are currently being sorted out and further info will be provided once this is done.

Retrieval Physician Guidelines Aviation resources The allocation of aviation resources is the responsibility of the AAV Flight Coordinator.
Aviation resources may not be available due to: weather conditions, pilot duty restrictions,
aircraft maintenance or performance issues, or other tasking.
Blood Transfusion Blood transfusion (or infusion of other blood products) is occasionally required for patients
being retrieved. In such cases blood must be stored in an appropriate approved blood shipping
container, and clear records must be kept of all agents used (including pack numbers). Where
available, standard transfusion documentation should be completed and handed over to the
receiving hospital clinical staff.
Case review & Audit • The Clinical Advisor or Director performs a document-based review of all ARV cases.
Data will be extracted from the records at this point to contribute to the ARV patient
record database quality indicators.
• The record is reviewed from the perspectives of compliance with documentary standards,
and clinical practice standards, and screened for the documentation of adverse events or
incidents that may have resulted in risk or harm.
• All cases are also screened from the perspective of logistics – assessing the smoothness of
a mission, its planning and execution, and the avoidance of unnecessary delays. Cases
include both patient-transfer cases, clinical-advice-only cases.
Clinical Practice Guidelines The Clinical Practice Guidelines developed by AV for use in the field by MICA and Flight
MICA paramedics are appropriate in general scope to the range of practice of medical
Retrieval Physicians. These CPG’s are overseen by the Medical Advisory Committee and will
be the initial reference point for ARV clinical practice.
The CPG’s are guidelines and do not strictly limit the scope of clinical practice of
practitioners, who in certain circumstances may reasonably work beyond or outside of the
guideline. The application of guidelines will be reviewed through the case review and audit
system, and appropriate feedback will be available.
• Additions to, or alterations to guidelines will occur through the processes of the Medical
Advisory Committee (MAC)
Command & Control During air missions, the pilot is responsible for the overall safety and management of
logistics. In flight the pilot is in control of all resources, and is responsible for all decisions in
relation to the aircraft, flight path, safe altitude etc.
The ARV coordinator is responsible for defining time criticality of a retrieval case.
The ARV coordinator will determine the crew-mix that has the most appropriate skill set for a
specific clinical scenario. Principle factors involved in this decision will be clinical
complexity and patient instability (actual and potential).
Communication & Public relations The coordinator and retrieval physician must remain mindful of the need for optimal
communication styles, and of communication strategies that may be applied to ensure
85
complete and clear communication of relevant clinical and risk related matters with the
referrer.
o Always allow the referrer to complete statements – do not complete for them / put
words in their mouths
o Reflective checking is valuable: “Thank you Dr X, I understand from your
statement that the patient is ….. – is that correct?”
o Ask direct risk related questions: “Dr, Do you perceive any major risks or hazards
in the transfer of this patient?”
o Leave the door open for further communication: “If you think of anything else
that may be important or that arises after this call, please phone me back”
• The retrieval physician must be aware of the high visibility nature of their work, and the
fact that they are often interacting with systems and individuals under pressure.
• A proportion of the work of ARV is considered ‘newsworthy’, and the involvement in
cases that may be considered such should be raised with the ARV office in the first
instance. The office may then liaise with press agencies via the corporate communications
area of AV.
• Individual staff members must be aware of and compliant with standard AV and public
service policies in regard to confidentiality and release of material to the media.
Contact and Availability The Retrieval Physician will be contacted by the ARV Call Taker, by phone.
The Retrieval Physician will be available to discuss the case with the ARV Coordinator
within 5 minutes.
All phone contact will occur via 1300 368 661 to enable voice logging for quality assurance
processes.
Calls to the referring hospital should be minimised. Requests by the retrieval physician for
additional information, insertion of lines or preparation of drug infusions should be made
through the ARV Coordinator, or by teleconferencing all involved parties. If the ARV
Coordinator is coordinating multiple concurrent tasks he/she may ask the retrieval physician
to communicate directly with the referrer.
The Retrieval Physician will at all times communicate in a professional manner, respectful of
the circumstance of the referrer, the stressful nature of critical incidents, and the role of ARV
and AV in the State Health System.
The Retrieval Physician, in conjunction with the RASO and ARV Coordinator should ensure
that both the referring and receiving hospitals are informed of the estimated time of arrival
(ETA) of the retrieval team. The retrieval physician should inform the RASO of ETAs on
departing and arriving back at Essendon. (Or on departing the referring hospital for road
missions.)
Credentialing Credentialing of retrieval staff occurs on an annual basis as a component of the performance
management interview.
Credentialing will be performed by the Clinical Advisor or Director and recorded in the staff
HR file.
Death of Patient All patient deaths during the care of an ARV physician must be notified to the Coordinator at
the earliest possible opportunity.
The ARV coordinator will report the death to the ARV Admin on Call at the earliest
appropriate opportunity. The case will then be flagged for early clinical review.
Deaths occurring in a metropolitan based vehicle (including Air, HATS and CPAV) must be
notified to the Duty Team Manager at Tally Ho. (RASO will arrange). Deaths occurring in a
regionally based vehicle must be notified to the appropriate control room. This will facilitate
an appropriate destination for the body.
The coroner should be notified in appropriate circumstances.
Peer support is available to all staff involved in the care of a patient who dies during transfer.
86
The deceased’s family will need to be notified of the death.
Debriefing • Retrieval physicians should take the opportunity to formally or informally discuss and
debrief each mission with other team members after each case. This presents a
mechanism to acknowledge good practice, highlight communication and to look for
improvement opportunities.
Documentation All cases will be documented utilizing the AV clinical information system (VACiS)
Guidelines for completion of the record are available.
Equipment • Daily checking of drugs and equipment (responsibility of the 0800-1800 retrieval
consultant)
• Manuals for all equipment are available in the ARV office.
• Equipment and drug checking Occurs daily at 0800hrs & after the completion of each
retrieval
o There are 4 kits in total to check
o The day shift Retrieval Physician– will check ALL Biomedical equipment
and the RED and BLUE bags and the YELLOW drug bag.
o An equipment checklist must be completed for each kit and anything found
missing can be sourced from the medical / equipment storeroom. The
completed checklist should be left with the kit. Anything used during
retrieval should be annotated on the list to facilitate restocking.
o Restocking - when restocking items, if there is found to be 2 or less of a
particular stock item remaining in the storeroom, you must flag that item for
ordering.
o IN HOURS - contact the ARV Business Manager. The BM will attempt to
source the required item – however if it is ‘out of stock’, there will be a time
lag between ordering and delivery. If the BM is not available, a message left
with the ARV Admin Assistant will be passed on.
o AFTER HOURS – write the item description on the whiteboard in the
storeroom and it will be ordered on the next business day.
o Drug Bag
o All expiry dates for drugs in the packs must be checked on the first of every
month.
o For drugs which are normally refrigerated, the date when they should be
discarded should be recorded on the ampoule.
o This would normally be 1 month for suxamethonium, 3 months for
rocuronium and pancuronium.
o Replacement Drugs can be obtained from the drug cupboard. Restricted items
are held in the drug safe – and must be checked in & out by two people. This
can be done by a FP &/or a MFP, and / or the FC.
Biomed Equipment Ventilators should be checked using a circuit & test lung with O2 cylinder located in
storeroom.
Monitors should be turned on and attachments checked.
Syringe driver battery level must be checked.
ZOLL monitor with external pacing should be tested.
iSTAT analysers – calibrated weekly
All ventilators, monitors and syringe drivers must be on charge while in the storeroom.
Faulty Biomed Equipment
87
Any equipment malfunction must be recorded in the Maintenance
Request/Defect Report book located in the storeroom. The faulty equipment
and the completed paperwork is to be given to the ARV Business Manager
(BM) in hours, and after hours the equipment and paperwork should be
placed in the ARV main office and an email sent to the BM. This will be
followed up on the next business day.
o Under no circumstances should faulty equipment be left in the packs or put
back on the shelf.
On Return From A Retrieval
o On completion of a mission the kit must be returned to base and restocked by
the retrieval physician so that it is immediately task ready.
o
Fatigue • ARV aims to minimise and manage the risk of medical staff fatigue in accordance with
duty of care obligations for crew and patients.
• The Civil Aviation Safety Authority (CASA) has prescriptive requirements for fatigue
minimisation for licensed aircrew engaged in emergency medical operations.
• These instructions have influenced the construction of this guideline.
• ARV will ensure that:
o A safety culture is established and maintained within the organisation
o All medical staff are educated in the identification and symptoms of fatigue
o Adequate rest and sleeping facilities are provided when necessary
o The principles of this guideline are understood by operational and
management staff.
•
ARV Medical staff will ensure that:
o The fatigue management guideline and system are understood and upheld
o Fatigue reduction methods are employed whenever it is practical to do so
during duty periods (see below.)
o Any infringement or safety issue that impacts on the fatigue management
guideline is reported to management as soon as possible.
Duty Periods
A duty period commences when the member performs any duty associated with the activation
of a medical task. This applies to on base and on call staff.
A duty period shall not exceed 12 hours except as provided for below:
o A duty period already commenced may be extended when medically essential
to recover the patient to appropriate medical facilities and the medical staff
consider themselves physically and mentally fit to do so. Where possible and
appropriate, arrangements can be made to replace fatigued staff for the final
leg of the mission (e.g. airport to hospital.)
o A duty period which contains a clear rest period of 4 consecutive hours or
more at suitable resting accommodation may be extended by up to 2 hours
(from 12 to 14 hours.) This extension may be applied once only during a duty
period.
o A duty period which contains a clear rest period with sleeping
accommodation can be extended by up to 4 hours (from 12 to 16 hours.) This
extension may be applied once only during a duty period.
o The ARV Coordinator must give approval to extend duty periods after
consideration of the medical aspects of the case and consultation with the
retrieval team.
Time Free of Duty
o When a duty period exceeds 12 hours, time free of duty shall be a minimum
of 10 hours.
o Staff should be aware of this when performing rostered on-call shifts vis a vis
their other clinical duties
88
On Call Periods
Prior to undertaking rostered on call shifts with ARV, medical staff should have appropriate
rest. The nature of this rest / preparation is influenced by the type and nature of work
previously performed, and the length of prior shift. Staff are required to apply a sensible ‘safe
hours’ approach, as would be their responsibility in normal medical workplace rostering.
Safety and Extended Duty Periods
Extended duty for Medical staff may be limited by aviation safety requirements of the
aircrew.
Medical staff must be mindful of fatigue implications for the pilots.
Extended pilot hours have implications for subsequent rostering.
Complex mission planning involving fatigue concerns should be escalated to ARV admin on
call.
Sleeping areas are provided or alternative transport arrangements (other than driving home in
private car) can be made for Medical staff to return home after working extended duty periods
>12 hours.
Handover A clinical handover includes the presentation of relevant history, examination and
investigations. It should also include current clinical progress, including patient response to
any interventions performed.
The number of handovers should be minimised to reduce the risk of important information
being ‘lost’.
All members of the ‘receiving’ team should have access to the handover. At the referring
hospital, this includes the retrieval physician and the paramedic. At the destination hospital
this includes medical and nursing staff. The ‘destination’ handover should be documented on
the patient care record.
The handover should occur in a manner that is safest for the patient and most efficient for
staff. In general, this is whilst the patient is on a hospital bed, as opposed to an ambulance
stretcher. The patient is attached to a ventilator with by piped oxygen; syringe pumps and
monitors can be connected to mains power. In an unstable patient, sufficient information to
facilitate resuscitation may be given initially, followed by a more complete handover as the
situation evolves.
At these handover interactions, retrieval physicians are the visible face of Ambulance Victoria
and Adult Retrieval Victoria. Professional behaviours are expected.
Incident reporting The purpose of the ARV Incident Report is to record any issues, unusual situations or
variations to normal practice relating to adult retrieval activities across the state.
• A multidisciplinary group will review the information captured on this form. This will
ensure that circumstances around an identified case are explored, any suggested actions
are considered and improvements to the system are introduced if required.
• Feedback regarding outcome of a report will be provided to the reporter in all cases.
• At present default (mandatory) reports would include:
o patient death in ARV care
o staff injury
o near miss / event with potential for patient harm (level 2 variation)
o actual patient harm due to error (level 1 variation)
o other critical risk (logistic or clinical)
Issues and Problems Issues or problems which may arise must be handled in a collegiate and professional
manner, with the patient well-being and clinical outcome the over-riding consideration. Issues
that cannot be simply resolved must be escalated to the Coordinator in the first place, and if
necessary to the Director ARV or the Clinical Advisor ARV.
Any issue or event which exposes the service or a patient to risk or which results in harm to
staff, public or patient must be reported via the ARV Incident Reporting framework
89
Leave Applications for leave should be submitted in advance to the Admin Officer ARV. Please
note that ARV will aim to accommodate all leave requests in line with other (external)
employment arrangements that RP’s may have, however this is not able to be guaranteed, and
there may be times when restrictions are placed on the availability of leave.
Provision of 6-8 weeks notice for leave requests is required.
Morbid Obesity Patients with morbid obesity (arbitrarily defined as: weight over 140kg, or BMI over 45) who
require mechanical ventilation for management of pulmonary pathology, or who require
mechanical ventilation and have other significant co morbidity, should routinely be crewed by
ARV doctor and Paramedic MICA if available. These patients must be considered clinically
very complex and at significant risk for transfer.
It is not possible to lift patients over 120kg into the current fixed wing aircraft due to
loading equipment limitations. This does not relate to rotary wing aircraft where patients over
120kg may be considered for transport on a case by case basis.
Night transfers Transfer must never be delayed in a time critical patient. (This includes patients with
significant risk of deterioration during the time delay).
Non Time Critical aviation transfers should not occur after midnight (air crew fatigue and
human factors issues).
It is imperative that the skill set and capacity to provide ongoing care at the referral site is
factored in any decision to delay a transfer.
All cases where transfer at night is delayed will be specifically audited.
Patient preparation and packaging Depending on sending hospital resources and expertise, patients may require little or
extensive interventions by the retrieval team before they are suitable to be transferred.
Requests to the sending hospital e.g. drugs pre-prepared in 50ml syringes should be made
through the coordinator.
It is not possible to lift patients over 120kg into the current fixed wing aircraft due to loading
equipment limitations.
Patients with IABP or ECMO require retrieval by a RP by road (transfer by fixed wing is
possible). A private perfusion service is available to assist. Retrieval Physicians should not
attempt these missions without the aid of staff familiar with the operation and troubleshooting
of this specialist equipment.
Performance Management Retrieval physicians will participate in yearly performance reviews which will be performed
in accordance with AV policy, and which are modified to ensure relevance and
appropriateness to medical staff.
The performance management system also defines the general scope of practice of the
retrieval physician.
Retrieval physicians will be expected to maintain a general level of health and physical fitness
appropriate for the physical requirements of their work and the retrieval environment.
Retrieval Logistics Both Road and Air departure points will normally be from Essendon Airport (AAV), where
all ARV equipment is stored and maintained. Equipment is not to be sent unescorted by taxi
due to safety issues surrounding the transport of drugs.
Early activation is imperative to optimise system efficiency and responsiveness. Activation
may occur prior to the known availability of a destination (receiving) hospital. Retrieval
physicians may be despatched before the coordinator is able to give full details of the task.
90
Activation includes early communication with all resources / platforms: AAV, Regional
Ambulance Control rooms, Metropolitan Ambulance Clinicians, DTM (for CPAV) and NPT
(for HATS.)
ARV departure response times of less than 30 minutes will be aimed for where necessary, and
all activation delays greater than 60 minutes will be audited.
It will therefore normally be impractical for retrieval physicians to be on call from a site that
is more than 15(-20)km from the metro centre or Essendon airport.
Recall times commence at the active commencement of a mission (leaving a site of recall),
and do not include advanced warning of (planned delayed onset) missions.
The retrieval physician is part of a retrieval team. They bring a certain skill mix, which is
supplemented by the skill mix of the (MICA) paramedic.
AV has a zero blood alcohol policy for all active staff.
Road resources The current options for road transport platforms include – emergency ambulance, CPAV,
HATS, non-emerg vehicle. Due to current staffing and crewing structures the standard
approach to road vehicle choice is as follows:
Ö HATS (with driver + Crit Care Nurse crew) is preferred option during periods of
availability, and if response time is appropriate, unless
Ö ARV Coordinator contacts HATS in the first instance as this is the preferred resource for
ARV retrievals
Ö If HATS is not available the ARV Coordinator contacts the Clinician
Ö In consultation with the ARV Coordinator the Clinician will provide the most appropriate
resource to accomplish the retrieval. In most cases this will be an AGP with at least one
ALS qualified paramedic aboard
Ö If the ARV Coordinator determines that the retrieval requires MICA skill sets to assist the
retrieval physician (uncommon), the Clinician will organize a CSO/SRU to accompany or
a MICA vehicle to do the transfer
Ö The Clinician may consider the use of a CPAV or Netcomm vehicle if they are able to
resource either unit with an ALS qualified or MICA paramedic
Ö If required, the ARV Coordinator can liaise with the Clinician to determine clinical
requirements prior to contacting the Clinician to organize the retrieval
Activation of HATS is performed via Coordinator contacting NPT (private ambulance
service) on 1300 628728 (The RASO will fax a booking form to Netcom also).

Safety Recurrent aircraft safety training will have a positive impact on flight crew emergency
preparedness. Aircraft loading and unloading competency is vital to safe operations on scene,
at helipads, and at airports. Mission profile, patient acuity, and aircraft performance all impact
the decision to perform hot or cold loads and unloads.
In addition to aircraft safety, crew and patient safety must be considered. Once the patient and
equipment have been secured on-board the aircraft, the air medical crew must ensure access
to the patient for any interventions that may be required at altitude.
Safety considerations and aircraft operations are essential components in the initial training
and continuing education of all personnel working in and around rotary-wing and fixed-wing
aircraft. The perspective and knowledge of an experienced pilot is a critical factor in the
training of air medical crew members
The flight crew members must work collaboratively with other services, including ground
ambulances to assure that all actions in and around the aircraft are safely carried out.
In general, ARV is not involved in “hot” loading or unloading .The pilot is responsible for
providing security of the main and tail rotors during all load/unload operations.
A helmet should be available for the Retrieval physician when flying in a helicopter.
91
Staff Welfare The nature of retrieval and coordination work can be stressful and difficult. Ambulance
Victoria offers all staff access to peer support and counselling services. These may be
accessed by individuals or via ARV management
Peer Support: contact via Corporate Paging (for duty peer support officer) 9483 8009;
Phone: 0419 002 956 Email: peer.support@mas.vic.gov.au
Counselling Service: Ms Heather Bancroft, VACCU
Phone: 9654 4144 Email: clinical.director@vaccu.com.au
Tarmac Handovers Are generally inappropriate, and patients should be retrieved from a hospital setting. This
allows for controlled handover, assessment of the patient, checking of all equipment,
connections, placements etc. All tarmac handovers will be considered a variation and audited.
(Exceptions may exist e.g. an uncomplicated AMI being transferred urgently for PCI – in
such a case the risks associated with tarmac handover are low, and the time benefit may be
great)
Team Performance Successful retrieval missions are dependent upon the performance of the team.
Cooperation, communication, diplomacy, respect and empathy are vital.
Team Performance = Skills x Behaviour
Trauma System Adult Patients
Ambulance services should triage adult major trauma patients and suspected adult major
trauma patients directly to an adult Major Trauma Service (The Alfred and the Royal
Melbourne Hospital), when the travel time is less than 30 minutes.
If a Major Trauma Service is not within 30 minutes travel time, then the patient should be
triaged to the next highest-level trauma service within 30-minute travel time, from the
accident site.
Specialist Trauma Triage and Transfer
Hospitals with neurosurgical specialities should manage neurotrauma patients requiring
critical care support.
Major trauma including spinal trauma should initially be triaged to a Major Trauma Service.
Early consultation by each treating hospital with the Victorian Spinal Cord Unit at the Austin
Hospital is essential to optimise patient outcomes.
Discrete spinal cord injured patients over 16yrs of age, in the absence of other indicators of
major trauma, should be triaged to Austin Health’s, Victorian Spinal Cord Service by
telephoning (03) 9496 5000 and asking for Spinal Unit Acute Registrar.
Multiple trauma, incorporating the need for microsurgery, should be referred and transferred
to a Major Trauma Service. St Vincent’s Hospital also have capacity as leaders to manage
injuries requiring microsurgery.
Neurosurgical triage and transfer guidelines for major trauma still apply in rural areas, even
where a neurosurgical specialist practises locally, as the management of these patients
requires all the appropriate and agreed service supports of a Major Trauma Service.
Major Trauma Triage Guidelines Require:
Pre-hospital major trauma to be identified according to specified physiological and
anatomical criteria.
Triage to a Major Trauma Service where a major trauma patient is less than 30 minutes
transport time from a Major Trauma Service.
Triage to the highest designated trauma service accessible in 30 minutes where a major
trauma patient is more than 30 minutes transport time from a Major Trauma Service.
Triage to a designated trauma service accessible in the least amount of time in isolated rural
areas that are more than 30 minutes from any trauma service.
Where a major trauma patient appears to be in an immediately life-threatening situation
during transport, the patient be diverted to the nearest designated trauma service for
92
stabilisation, with subsequent transport to a Major Trauma Service at the earliest appropriate
time.
Where a patient is triaged initially to a non-Major Trauma Service for stabilisation, early
liaison with the Major Trauma Service should occur via the Trauma Advice and Referral
telephone line 1800 700 001, which is answered by ARV calltakers. Consideration of
appropriate medical retrieval or interhospital transfer to a Major Trauma Service can then
occur from the initial call.

available on request
See Appendix 2 for safety card.
Emergency Exits and doors Two doors for regular use, both located on left rear of aircraft. Cargo door for
loading/unloading of stretcher. Passenger stair door is located within cargo door. The
passenger stair is also one of the emergency exits.
The second emergency exit is at the front right side of the cabin over the wing.
In case of a water landing, ONLY use the emergency exit on the right side over the wing. DO
NOT use the rear exit in case of a water landing, as the cabin will quickly fill with water.
Pre flight safety briefing Before every flight the flight paramedics will do a safety briefing
Seat belts Must be worn during the following times:
During takeoff.
During landing.
Flights below 1000ft.
95
Turbulent conditions.
As directed by the pilot.
By patients at all times.
Flight paramedics will give instruction in the correct
fitment of seatbelt.
Prior to take off and landing an audible tone will sound
to remind passengers to fasten seat belts.
Emergency Oxygen during Cabin Depressurisation All pressurised aircraft are required to have an
emergency oxygen system.
The King Air has a system that automatically deploys if
there is a cabin depressurisation. This occurs above
12500ft.
Yellow cup like oxygen masks (similar to commercial
airlines) will drop from the midline of the roof. Should
they deploy, fit your own mask immediately. Pull on the
mask to activate oxygen.
Put your own mask on first, and then assist others.
Fogging and wind rush might occur in the cabin.
The pilot will dive steeply and rapidly.
Seat belts must be worn.
Fire extinguishers Two 1kg fire extinguishers:
One under co-pilots seat in the cock pit (right hand seat).
One in rear of cabin on the left of the cargo door adjacent to the rear left hand seat.
Each contains approximately 25-30 seconds of
extinguishing agent.
Instructions:
Remove locking clips.
Pull the safety pin.
Hold unit upright, aim at the base of the fire.
Squeeze the trigger while doing a side to side
swinging motion.

Emergency Locator Transmitter (ELT) In the event of a forced landing in an emergency situation the ELT automatically activate.
This activation is via a 7G force impact.
Should it not activate automatically, there is a manual switch located on the right side of the
cockpit console between the pilot seats. A plastic cover protects a red switch and light.
(Pictures above)
In the event of an impact a red light will be flashing. If not the ELT should be manually
activated.
Emergency Landing Wait for paramedic to call BRACE BRACE BRACE.
There will probably be more than one impact.
97
Wait for the aircraft to come to a complete stop.
Be prepared to evacuate the aircraft to a safe distance.
The paramedic is responsible for the evacuation; however he may not be capable.
Life jackets Stowed under your seat.
Life jackets must be worn:
In an emergency situation on over water flights
In a low level flight over water (under 2000ft)
At the pilot’s discretion.
Spare life jackets are kept in the rear cabin cabinets.
A portable life raft will be loaded onto the aircraft if a flight over a great distance of water is
planned (e.g. to Tasmania).
The life raft contains a portable ELT that requires manual activation.
After activation of the life raft ELT, attach it to the raft with its own tether line and allow it to
freely float in the water.
The life raft carries basic survival equipment and water. It is advisable to retrieve the aircraft
survival kit.
Airside Safety The airside is the movement area of an aerodrome, adjacent terrain and buildings or portions
thereof, to which access is restricted. Commonsense and vigilance are required at all times
when airside.
Airside rules
High visibility vest are required to be worn at all times when airside (Pilots and passengers
are exempt if they are moving directly to or from the aircraft for operation purposes).
Aircraft always have right of way over vehicles, equipment or pedestrians.
Never park or stand within 3 metres of any aircraft unless you are directly involved with that
aircraft.
No person is permitted within 30 metres of a helicopter or a helicopter landing site unless
essential to the helicopter operation.
No smoking, alcohol or any banned substances are permitted to be consumed airside.
Never stand within 15 metres of a refueling aircraft.
Mobile phones are not permitted within 15 metres of a fuel hydrant point or aircraft that is
being refueled.
Never approach a jet or propeller driven aircraft with its engine/s running.
Never approach a helicopter with its engine/s running (unless escorted or entering or
departing the aircraft following specific procedures discussed in safety around helicopters).
Beware of the direct effects of jet blast and propeller wash and their effects on debris.
Foreign Object Debris (FOD) causes Foreign Object Damage – If you see debris – pick it up.
Beware of what you put down and where (light weight bags/equipment) – it may blow into
the path of an aircraft.
Be aware of vehicles moving around the airside – fuel trucks, maintenance and emergency
vehicles.
Only authorised vehicles with an operating anti collision light or vehicles being escorted by
an authorised escort are permitted airside.
Airside emergencies – depending upon the nature of the emergency, emergency services
should be notified if necessary and the airport duty operations manager must be notified in all
instances. In the event of a ‘full’ emergency the airport will be closed and all unnecessary
persons are to clear airside.
98
Strategies for controlling risks/hazards Wearing appropriate clothing and footwear e.g. flame retardant flight suits and undergarments
and sturdy flat soled footwear. (No high heals – they are likely to get caught in the Douglas
tracking in the floor)
Using ear plugs on the tarmac and good quality headsets within the aircraft.
Securing all items within the aircraft.
Wearing seatbelts/harnesses at all times.
Listening to in-flight briefings and following directions of the flight crew.
Be well rested prior to duty and keep hydrated during flights.
Most importantly: maintain an awareness of your surroundings, use ‘common sense’ and if in
doubt – ask somebody who knows!
Fixed wing aircraft (FW) danger areas Propeller driven:
Propellers: large and spin at high speeds which make them difficult to see.
Exhausts: Piping hot emissions and exhaust remain hot for a period of time after shut down.
Jet driven:
Engine intakes – sucks in an enormous amount of air when engine is running.
Engine outlet: jet efflux is extremely hot gas.
Approach to a fixed wing aircraft It is normal practice to be in the cabin of the
FW with the doors closed prior to engine start.
The pilot will advise when clear to open doors
following engine shut down and when
propellers have stopped turning.
Approach and depart FW from the side
remaining well clear of the engines.
Remember: a propeller might still turn with the
engine shut down.
Approach to a ROTARY wing aircraft Approach to the helicopter should be limited to
pilot authorised movement.
All approaches should be within direct vision of
the pilot and acknowledged by them
Areas to the rear of the helicopter are ‘no go’
zones.
Cabin safety Command:
The Pilot in Command (PIC) is in sole command of the aircraft and its operation. No one may
load, equip or enter the aircraft without the knowledge and permission from the PIC.
The PIC will give commands regarding procedures to be undertaken when in the aircraft.
Seatbelts: must be securely fastened prior to take off and remained fastened until after landing
(unless restrained by an approved harness).
Exits: Identify your primary and secondary exits, their operation and reference point to locate
them. Remember this will be different for each seating position in the aircraft.
Communication: there should be no communication over the intercom during times the pilot
is communicating with air traffic control such as when receiving clearances or instructions
99
and during take off and landing unless essential to aircraft safety. If necessary to
communicate with other medical crew during these times – request to be isolated from the
cockpit.
Controls: No person shall operate or interfere with any aircraft control, instrument or aviation
radio unless specifically requested to by the PIC.
Equipment stowage: No item should be loaded into the aircraft without the knowledge and
permission of the PIC.
Safety equipment: Safety equipment such as life vests/jackets should be worn when provided
by the crew. Even though the flight may not be anticipated to go over water, an unexpected
diversion may occur necessitating.
Observation:
It is important that all persons onboard the aircraft keep a good look out during all phases of
flight for anything that may pose a hazard to the aircraft and report the hazard to the PIC e.g.
other aircraft, power lines, people, animals.
When reporting a hazard give an indication of its position using the clock method, i.e. 12
o’clock is the nose of the aircraft, 6 o’clock the tail, 3 o’clock directly right, etc.; an
estimation of the distance and if relevant the level.
Briefings: prior to take off a briefing shall be given in accordance with Civil Aviation order
(CAO 20:11):
Use of flotation devices where applicable
Smoking, including the prohibition of
Stowage of hand luggage
smoking in toilets
Presence of on board special equipment
Use and adjustment of seatbelts
where applicable
Location of emergency exits
Use of oxygen where applicable
Emergency Procedures
In the event of an in-flight emergency:
Ensure you are secure
Ensure the cabin is secure
Familiarise yourself with your emergency
exits
Follow the instructions of the PIC.
Post landing:
Exit the aircraft following safe departure
procedures
Assist other WHERE SAFE TO DO SO,
and provide first aid
If in a remote area: Establish shelter, gather all emergency/survival equipment, ration
water/food, have signalling equipment prepared, ensure you know how to use it and use it at
an appropriate time.
If in the water: ONCE OUT OF THE AIRCRAFT inflate your life jacket, deploy the life raft
if carried on board, turn on ELT, prepare signalling equipment, dry out raft and prepare
rations.
Bottom line
The key to aviation safety is COMMON SENSE. Follow the directions of those whose
primary business is aviation and remain aware of your surroundings.

Retrieval Medicine This section of the ARV manual is dedicated to specific clinical issues and in particular to
relevant aspects of their management in the retrieval setting.
It is not intended that this section be a ‘cloned textbook’, rather that it investigate common
retrieval clinical scenarios, define the particular challenges and risks of the most complex
transfer challenges, and present methods of awareness, risk mitigation and clinical
optimization.
This section assumes clinical knowledge at or close to specialist / consultant level and aims to
take the advanced clinician to the next level in retrieval medicine.
101
Airflight Medicine –the basics The Effects of Altitude on Gas Volume Boyles Law
"When the temperature remains unchanged, the volume of a given mass of gas varies
inversely to its pressure."
In flight terms, as your aircraft ascends, increasing in altitude, the barometric pressure
diminishes. Any gas within an enclosed space will expand. Alternatively, as the aircraft
descends and barometric pressure increases, the gas will contract.
The Effects Of Altitude On Oxygen Availability Dalton’s Law: Pt = P1 + P2 + P3 + … Pn
Dalton's law states "the overall pressure of a gas mixture is the sum of the individual or partial
pressures of all the gases in the mixture."
In flight terms, oxygen is "thinner" in the upper atmosphere. Why? At sea level the barometric
pressure is 760 mm Hg, and the atmosphere is composed of 20.95% O2. As altitude increases,
the barometric pressure decreases, and the molecules in the atmosphere move farther apart.
While oxygen still comprises 20.95% of the atmosphere, there are less oxygen particles per
cubic millimeter to be utilized.
Clinically, an increase in altitude diminishes the oxygen available to the body and can result
in hypoxia. For instance, at 12,000 feet the barometric pressure decreases to 483 mm Hg. The
composition of the atmosphere remains the same, and so the percentage of oxygen remains at
20.95 percent. However, the partial pressure of oxygen will decrease to 101.19 mm Hg.
The Effects Of Pressure Changes On Gas Bubble Formation Henry's Law
Henry’s law states "...the quantity of gas dissolved in 1 cm3 of a liquid is proportional to the
partial pressure of the gas in contact with the liquid".
In clinical terms, an example of gas solubility in a liquid is decompression sickness (a.k.a.
"the bends"). As a diver ascends, the pressure is decreased on the nitrogen gas dissolved in the
blood. Ascending too quickly or flying within 24 hours of a dive can result in nitrogen bubble
formation in the blood, which can cause dire clinical consequences. Treatment includes 100
percent oxygen and rapid descent treatment in a hyperbaric chamber and may be necessary if
the symptoms do not resolve.
Altitude restriction in air transport is a consideration in only a few rare cases. When
transporting a patient with decompression sickness, altitude should be restricted to less than
1000 feet above ground level. An untreated pneumothorax is an absolute contraindication to
air transport. Prior to take-off, treatment with a chest tube or temporizing one-way valve
system is required. Decreased flying altitude results in increased turbulence, longer flying
times, and increased fuel consumption over a decreased aircraft range, consequences which
must be considered when a patient requires low altitude flight.
Stresses Of Flight In addition to hypoxia, barometric pressure changes, and thermal variations, the stresses of
flight include noise, vibration, humidity/dehydration, gravitational forces, third spacing, and
fatigue.
Noise
Permanent or temporary hearing loss may occur for patient or provider. The longer the
exposure, and the more intense the noise, the greater the potential damage. Consequences
include headaches, fatigue, nausea, vertigo, stress, and reduction in task performance
effectiveness. Noise may interfere in provider communications with the patient and other
crew members, and impedes the ability to auscultate the lungs, heart or blood pressure.
Hearing protection should be worn by patient and crew, and includes earplugs, headsets, and
helmets.
102
Vibration
Vibration results from the aircraft motor/rotors and can be due to turbulent weather. Vibration
may result in an increase in metabolic rate, fatigue, shortness of breath, motion sickness, and
an inability to properly thermo-regulate. Low frequency vibration of the eye may cause visual
decrements. Vibration in general is less well tolerated in the supine position due to x-axis
vibrations. Neonates are most susceptible to direct injury from vibration and noise. Care must
be taken with fractures, as the vibration may increase discomfort at the fracture site or from
an inadequately padded and secured splint. Special consideration must be given to patients
with electronic monitoring as in-flight vibration may interfere with invasive and non-invasive
monitoring, and may cause dysfunction of activity-sensing pacemakers. Protection from
vibration is essentially limited to isolating the individual and equipment from the aircraft by
use of adequate padding.
Humidity/dehydration
Patients and crew flying at high altitude for prolonged flights will be exposed to very low
humidity and may develop dehydration. Patients in a hot environment or with pre-existing
dehydration may have an exacerbation of their condition, and attention should be paid to oral
and IV fluid intake and urine output when appropriate. Additionally, respiratory secretions
may become thick, resulting in less efficient gas exchange and contributing to hypoxia.
Dehydration may be prevented through humidified oxygen and adequate fluid intake.
Gravitational Forces
Gravitational forces are most evident on ascent and descent, or when the aircraft changes
speed or direction. Patient positioning during maneuvers may affect blood pooling and
intracranial pressure. For example, in a cardiac patient it may be advantageous to position
them with their head toward the rear of the aircraft during ascent, so that the G-forces help to
pool blood in the upper part of the body. Conversely, in patients with intracranial injury or
volume overload, a position with the feet toward the rear of the aircraft during ascent may
pool fluids in the lower extremities and avoid a transient and potentially detrimental increase
in intracranial pressure.
Third Spacing
Third Spacing is the loss of fluid from the intravascular space to the extravascular space in the
tissues. This phenomenon is due to the effect of pressure changes and cellular increases in
permeability resulting in fluid transitions. The effects of third spacing include edema,
dehydration, tachycardia and hypotension. These affects may be complicated by other stresses
of flight, including thermal variations, vibration, and gravitational force effects.
Fatigue
Fatigue is generally felt to be a culmination of all of the stresses of flight. Tactics should be
taken by the aircrew to minimize the effects of flight and personal stresses to maximize
effective performance, alertness and safety.
Pressurized Environments In order to minimize the effects of barometric pressure changes and subsequent hypoxia, a
controlled flow of compressed air can maintain a constant pressure in a fixed-wing aircraft.
Typically the cabin pressure can simulate an 8,000–10,000 foot altitude while flying at an
actual altitude of greater than 40,000 feet. Malfunction of the aircraft’s pressurization system
or structural damage sustained by the aircraft may result in rapid decompression. The crew
must understand this emergency, and be ready to respond. A loss of pressure through a large
defect results in a rush of air towards the defect. Any person or equipment not adequately
restrained may be blown about the cabin or through the defect due to the development of
cyclonic winds. Decompression sickness, hypothermia, hypoxia and expansion of GI tract
gases resulting in decreased respiratory movements and vaso-vagal syncope can result from
this loss in cabin pressure. Hypoxia is the most important immediate consequence of rapid
decompression. Supplemental oxygen must first be supplied to the pilot, the crew, and then
the patient or passengers. Recall that gas in medical systems will rapidly expand, and any
catheters, chest tubes, NG tubes, or drains should be unclamped. Losing cabin pressure may
also result in decompression sickness. This, however, is rarely a problem under 25,000 feet
103
unless the patient has been exposed to compressed gas (i.e. scuba diving) within 24 hours of
the event. The nitrogen gas bubbles can result in a decrease or blockage of blood flow to any
organ system, and causes a wide variety of symptoms depending on the system affected.
Treatment includes application of 100 percent oxygen and rapid descent in altitude.
Unresolved symptoms will require treatment in a hyperbaric chamber.
Confined Spaces A final mention should be made of the challenges of the confined space in which the crew
must work. The tight quarters necessitates efficient use of space, compact equipment and
conservative storage of supplies. Equipment inventory should be replaced after each transport.
Advanced planning regarding patient access is also required.

Addisonian Crisis Key Clinical information
Consider in patients with lethargy, abdominal
pain / symptoms and cardiovascular collapse.
Consider in patients with hypotension
unresponsive to fluid and pressors especially
those who may have been on long-term
steroid treatment..
“Red Flags”
Cardiovascular Collapse
Often there has been a precipitant of
Addisonian crisis., particularly sepsis.
Key to treatment is to replace cortisol. It may
take 4-6 hours to see benefits of cortisol.
Hyponatraemia (Hyperkalaemia)
Hypoglycaemia
Investigations
It is important to begin treatment with intravenous steroid as soon as possible in critically ill
patients. However if time allows collecting the following blood tests will help in conformation
of a diagnosis
Cortisol
ACTH
Acid Base Status
Glucose
UEC
Synacthen with cortisol readings at
0 and 30min.
Interventions
The primary treatment of an Addisonian crisis is fluid resuscitation with N saline and
administration of IV steroid.
May require correction of hypoglycaemia with 50% dextrose.
Other treatments will be supportive. Supportive therapy will be required as hydrocortisone
may take 4-6 hours to become effective. Treatment may include vasopressor support, careful
monitoring of electrolytes and fluid balance. To facilitate this central venous access may well
be required.
Suggested medications
Hydrocortisone (Addisonian Crisis)
Fludrocortisone
IV
PO
200mg then 100mg at 6 hrs
0.1 – 0.3 mg daily
Specific Advice
In patients with known Addison’s disease who have infectious disease, are involved in trauma
or surgery, steroid replacement is crucial.
Normal daily steroid intake in these patients would be 30mg of hydrocortisone daily, 20mg on
awakening then 10mg at 1800.
For elective surgery 50-100mg of hydrocortisone should be given as a pre-med, followed by
150mg / day in divided doses in the recovery period.
Hydrocortisone is a better choice than dexamethasone which has limited mineralocorticoid
activity.
Retrieval issues
Retrieval may be of a primary Addisonian patient, or a known Addisonian patient who has
been involved in a physiologically stressful event which triggers a crisis.
It may take hours for intravenous steroid to have a noticeable effect.
The retrieval physician will need to support circulatory collapse and to monitor and treat fluid
depletion and electrolyte imbalance, taking an iStat may help with this.

Beta Blocker Toxicity Key Clinical information
Risk Assesment – Major toxicity expected
with Propranolol (non selective, lipophilic so
penetrates CNS) and Sotalol – (risks of
arrhythmia)
Readily absorbed, onset of effect may be
within ½ hr but usually 2-4 hours, however
Sotalol effects may occur up to two days
later.
If not Propranolol or Sotalol then course
likely to be more benign. If well at six hours
then no significant toxicity.
“Red Flags”
Caution in elderly, esp with Heart Failure
Co-existing airways disease (risk of
bronchospasm)
Co-ingestion of other cardiac meds especially
Ca channel blockers / digoxin
INVESTIGATIONS
ECG – 1st degree HB an early sign of toxicity
May have 1st-3rd degree block, junctional
bradycardia, ventricular bradycardia or even
asytole.
QRS >100ms predictive of seizures,
Clinical Features –
CVS –Hypotension + Bradycardias > may be
life threatening
CNS – Delirium, Coma, Seizures
Other – Bronchospasm (rare)
Hypoglycaemia
QRS widening in Propranolol toxicity is
predictive for ventricular arrhythmia +
seizures.
Sotalol causes QT prolongation, can lead to
Torsades de Pointes
BSL – given potential to cause
UEC hypoglycaemia
QRS >160ms predictive of ventricular
arrhythmia
Interventions
Supportive Care – Attend to airway if required, coma + seizures are likely if
significant Propranolol toxicity.
Treat Seizures conventially with benzodiazepines
Treat propranolol toxicity with wide QRS as if TCA toxicity, i.e Hyperventilate and
use Sodium Bicarb titrating to pH >7.50
Treat Torsades with : DC shock.
If refractory, then give :Isoprenaline bolus 20mcg, repeat as required, then infusion, may need high doses.
Overdrive pacing (rate 120-140bpm)
Suggested medications
Fluid bolus
20ml/kg for hypotension
Atropine for symptomatic bradycardia
0.5 to 1.0mg, rpt after 15 minutes
Inotropes
Conventional treatment may fail, expect
to need large doses.
Consider high dose isoprenaline infusion
for symptomatic bradycardia.
108
Glucagon.
5-10mg bolus followed by 5-10mg/hr
infusion if good response. NB This will
rapidly exhaust most hospitals supplies.
Activated Charcoal
if within 1st hour or once airway secure.
Specific Advice
Obtain toxicological advice
Seek and treat hypoglycaemia
Severe bradycardia may require
transvenous pacing

Basic resuscitative measures and supportive care ensures survival of the vast majority of
patients.
Bradycardia is common but treatment is only required in the presence of hypotension or
evidence of decreased end organ perfusion.
Occasional paradoxical hypertension should be treated very cautiously as it is transient and
likely to be followed by hypotension.
Suggested interventions
Bradycardia
Hypotension
Naloxone inconsistently reverses
CNS and respiratory depression.
Atropine, cathecholamine infusion, pacing
Fluid bolus 10-20ml/kg
Treat bradycardia
0.1mg IV q30-60 seconds, or
0.4mg SC/IM.
Specific Advice
Activated charcoal only after intubation as GCS can deteriorate rapidly.
Retrieval issues
Consider intubation prior to retrieval as rapid deterioration of GCS and BP may occur.
110
Confirmation of Central Venous Catheter Placement Key Clinical information
Inadvertent administration of vasoactive infusions through arterial lines can cause serious
complications.
Adverse events have occurred when retrieval teams have continued infusions through femoral
lines placed at referral hospitals.
Confirming that the line is venous (and not arterial) before commencing or continuing
infusions will prevent such complications.
“Red Flags”
Insertion during cardiac arrest or severe low cardiac output state
Insertion by inexperienced personnel
Femoral or brachial placment
Investigations
To confirm central venous placement of a line
Aspirate blood from distal lumen (confirms intravascular placement)
Connect to pressure transducer and assess pressure & waveform
Consider performing blood gas analysis
The value of obtaining a CXR after subclavian or internal jugular line placement must be
weighed up against the increase in scene time incurred.
Pneumothorax may not be detected on initial CXR (especially if supine.)
Interventions
If there is concern about the position of any intravascular line it should not be used
Arterial lines should be clearly labelled.
Retrieval issues
It should be routine practice to (at least temporarily) transduce any central venous line.
Continous monitoring of CVP during retrieval may be useful in some cases
Tension pneumothorax may develop from an occult pneumothorax at altitude.
111
ECMO Retrieval Retrieval Team The standard ECMO Retrieval Team consists of 5 members:
-
-
2 Alfred Team members (Usually 2 intensivists but may be Dr(s)+/-RN) - Clinical
leadership of the team will be provided by the senior intensivist. The Alfred
intensivist is responsible for perfusion management of the ECMO circuit.
ARV Retrieval Physican - The general role of the retrieval physician is to provide an
expert clinical interface with equipment and the practicalities of the retrieval process.
Paramedic – The paramedic is the clinican who is the expert interface between AV
environment, equipment and processes.
Pilot or single CPAV attendant - During air missions, the pilot is responsible for the
overall safety and management of logistics. In flight the pilot is in control of all
resources, and is responsible for all decisions in relation to the aircraft, flight path,
safe altitude etc. The CPAV attendant is responsible for operation of the stretcher,
lifting devices, and stabilisation of stretcher and equipment within the vehicle
(including power and gas supplies)
Equipment Other than the ECMO specific equipment, all retrieval equipment is provided by ARV. This
means the RP is the clinician familiar with infusion devices, drug pack, monitor and
ventilator. The RP is the hands on clinician who is relied upon to operate this equipment.
The RP is responsible for ensuring that there is good communication about settings and drug
dosing. The RP should ensure and communicate that there are adequate supplies of infusions,
oxygen and drugs for the entire, often lengthy retrieval. At a minimum, sufficicient sedation,
muscle relaxants and vasoactive infusions for the expected mission duration must be made-up
for rural ECMO missions. Ensure enough (at least three and perhaps more) infusion pumps
are taken for the job.
Generally there is time and space for the retrieval physician to sort out equipment, drugs, and
rationalise infusions during the ECMO cannulation process to reduce scene time.
Cannulation Most ECMO retrievals will be percutaneous, bilateral, peripheral, Seldinger technique
femoral cannulations although central (in theatre) or internal jugular options exist. The
cannula positions are often checked by ultrasound if available. A heparin bolus may be
requested towards the end of the cannulation process.
Veno-venous (VV) ECMO (for respiratory failure)
- One cannula tip is situated in the IVC – this is the access cannula, which draws dark
venous blood to the ECMO oxygenator.
- The other cannula tip is inserted to situate in or near the right atrium - this is the
return cannula for bright oxygenated blood.
If these cannula tips are too close together, already oxygenated blood can be drawn
back into the circuit.
Veno-arterial (VA) ECMO (usually for cardiac failure)
- The venous access cannula is usually at the right atrium.
- The arterial cannula is situated in a large (often femoral) artery for returning
oxygenated blood and also to supplement cardiac output. This cannula maybe in
another large artery if placed during cardiac surgery.
112
ECMO Circuit The ECMO circuit has 3 main components:
- The ECMO console, which provides the drive cable to the pump head and indicates
circuit flow rate. This is usually placed between the patient’s legs when pushing the
patient stretcher and tied down on the CPAV shelf or on the floor of fixed wing
aircraft.
- Has a centrifugal pump in the circuit which is driven by the ECMO console (or
manually in an emergency by a pump handle). This pump is clamped onto the patient
stectcher.
- An oxygenator in the circuit. This is also clamped onto the patient stretcher.
Clinical Considerations Sedation
All patients should be adequately sedated and paralysed with muscle relaxant prior to
cannulation and for the remainder of the retrieval.
Ventilation
Once the ECMO circuit is operating and oxygenation has improved, the aim of ventilation is
to prevent further ventilator related lung injury. The Alfred intensivists will help guide
settings. One common approach for retrievals is to select a safe pressure control setting eg:
inspiratory pressure of 30 and a safe PEEP of 15. Tidal Volumes may be very small in
patients with stiff lungs eg 150mls.
CO2
ECMO is more effective at removing CO2 than oxygenating blood. The oxygenator is
connected to an oxygen source with normal oxygen tubing such as the green tubing used with
a Hudson mask. This oxygen supply rate determines the amount of CO2 removed by the
oxygenator, analogous to minute ventilation to the lungs. Lung minute ventilation will also
contribute to the arterial CO2 but to a lesser extent. The end tidal CO2 becomes a poor
predictor of arterial pCO2, making it mandatory to carry I-Stat cartridges.
Oxygenation
FiO2 may still need to be 1.0 to aid oxygenation during the retrieval. To avoid oxygen
toxicity, the medium term aim is to be below a FiO2 0.7. Low FiO2 may result in reverse O2
diffusion from the ECMO blood to alveolar gas.
It is worth noting that increasing O2 supply flow to the ECMO oxygenator does not increase
ECMO oxygenation of the blood. It is by increasing ECMO circuit blood flow, particularly in
VV ECMO, that patient oxygenation is increased.
Many patients have permissive hypercapnia prior to ECMO institution. The rapid fall of CO2
when the circuit is switched on (as well as decreased right atrium pressures with VA ECMO)
can cause hypotension.
Intravascular Volume State
During VV ECMO there is a trade off between
1) Keeping vessels full – particularly the IVC – so that the ECMO cannulas can draw
blood at an appropriate rate, and,
2) Worsening oedema of the lungs with high filling pressures.
In the acute/retrieval setting the effective operation of the ECMO cannula usually takes
precedence and there may be a request for vascular filling, often with4% Albumin (if
available). The forces of acceleration/deceleration/ turbulence/rough roads on the IVC around
113
the venous cannula in VV ECMO and can drastically reduce flow rates, decreasing
oxygenation. Adequate filling above usual CVP parameters may help reduce these effects.
Patient Movement
Patient movements and transfers should be minimized and will occur in well-lit, protected
environments. All transfers(e.g. from bed to trolley etc) require a team of at least 5 people.
The RP should direct this team and be responsible for managing the ETT, standing at the
patient’s head. The Alfred intensivist will be responsible for managing the circuit and lines.
Effective communication between all team members if extremely important to minimise the
risk of catastrophic accidental line removal.
To bring a Victorian AAV aeroplane into a hangar usually requires an accredited engineer and
needs to be pre-planned.
ECMO Transfers : ECMO retrieval in Victoria is an advanced collaborative system involving ARV (AV) and
The Alfred Hospital, working within a formal memorandum of understanding.
ARV is the principal organisation in regard to retrieval in Victoria and is responsible for
coordination and delivery of critical care advice, outreach support and retrieval.
ARV provides support for many patients with severe (critical) cardiorespiratory failure, a
small proportion of whom may be considered for ECMO. The processes for ECMO retrieval
are broadly described in the attached flowchart.
Key concepts include:
Optimal communication between all parties involved in retrieval work is essential. To this
end, ARV uses teleconferencing and videoconferencing technologies extensively. (All calls
to and from ARV are recorded for quality purposes)
Where patients are referred to ARV regarding potential ECMO transfer/commencement, or
where they meet general ECMO inclusion criteria, the ARV coordinator will initiate a
teleconference involving the Alfred Hospital ICU consultant.
Where the Alfred hospital receives direct referral of patients for ?ECMO transfer, the ICU
consultant will contact ARV to ensure commencement of a teleconference involving the ARV
coordinator from the outset.
All ECMO retrieval staff will be fully credentialed.
Decisions will be made jointly and collaboratively. Issues that cannot be resolved will be
escalated to the ARV and Alfred ICU directors (or delegate)
Prior to any ECMO mission, the ARV coordinator will convene a “Summary
Teleconference”. This will be attended by all involved clinical and logistics parties or the
case must not proceed. In this teleconference, the plan including contingencies will be
discussed and agreed.
During ECMO transfers:
The ARV coordinator is the clinical ‘control point’ for all retrievals. They are responsible for
defining time criticality of a retrieval case, and for overall coordination of crewing, logistics
and resource.
All case communication will occur through the ARV RASO / coordination office.
All transport coordination will be provided by ARV utilising AV transport platforms.
Urgency of outbound legs will be discussed with the ARV coordinator who will coordinate
platform responses via AAV, ERTCOM or NETCOM.
Standard crewing will be: Paramedic, ARV retrieval physician, Alfred Team (Intensivist(s),
+/-ICU RN)
Clinical leadership will be provided by the senior intensivist
Operational leadership and environmental guidance will be provided by the ARV retrieval
physician
114
Patient movements and transfers will be minimized, and will occur in well-lit, protected
environments (e.g. a hangar rather than open tarmac).
During air missions, the pilot is responsible for the overall safety and management of
logistics. In flight the pilot is in control of all resources, and is responsible for all decisions in
relation to the aircraft, flight path, safe altitude etc.

Hyperosmolar non­ketotic coma (Hyperosmolar Hyperglycaemic crisis) Key Clinical information
Glucose typically higher than in DKA
(always >33 mmol/L; often up to 60
mmol/L)
pH typically >= 7.30
HCO3 > 18mmol/L
Anion gap variable
Often occurs in patients not previously
known to be diabetic
Typically no ketosis / acidosis, but may coexist with DKA in 20-40% of cases
“Red Flags”
Look for signs / history of precipitants:
pneumonia, UTI, gastroenteritis, cardiac
disease, medications (esp. thiazides, betablockers, Ca antagonists)
INVESTIGATIONS
Monitor BSL every hour and
A or VBG with electrolytes at
least every 2 hours until
stable.
Expect a high WCC due to
haemoconcentration, not
necessarily because of
infection
More dehydrated than DKA (usually 8-10L)
Serum osmolarity > 3230 mOsm/kg
Alteration in mental state
Occasionally seizures
Has a much higher mortality than DKA (up to
60%) due to the ages / comorbidities of the
different patient profiles.
A high anion gap metabolic acidosis may be
due to co-existing ketoacidosis, but may also
be a lactic acidosis related to the underlying
cause. Check lactate if possible.
UA with ketones
Mg2+ and K+ often fall
dramatically with insulin
therapy
ECG for signs of
hyperkalaemia
CXR
Cultures – urine, blood, +/sputum
Whole body K+ is typically
depleted despite high initial
K+;
Whole body Na+ is typically
reduced, despite high initial
Na+. Note corrected Na+ =
measured Na+ + 0.4 x (glc –
5.5)
Interventions
Treatment of dehydration is the first priority
Historically, endocrinologists recommended initial fluid resuscitation with 0.9% NaCl. More
recently, intensivists / ED physicians, observing the hyperchloraemic acidosis this causes, have
recommended Plasmalyte or Hartmann’s solution.
Typical regimen in an adult :
1L over 1st hour
1 L over 2 hours
& then titrate to clinical indices (urine output, cardioresp. signs).
Consider use of vasopressors if fluid therapy is insufficient to quickly restore MAP>65-75.
124
Treatment of hyperglycaemia is the second priority.
Hyperglycemia will often resond to fluid resuscitation
Commence insulin infusion 5-10 units/hr IV, aiming for a fall in glucose of approx.. 5
mmol/L/hr but keeping the glc>12 mmol/L for the first 24 hours.
When BSL falls to 12mmol/L, add 5% D at approx. 100ml/hr in addition to whatever volume
resuscitation is indictaed at that time.
Do not start insulin if K+<3.0mmol/L; correct K+ first (with eg. 30mmol IV over 1 hour
repeated as required
Electrolyte replacement
Expect to need to give KCl 10-30 mmol /hr IV when K+ falls to <5.5 mmol/L
Expect to need to give 1-2 x Mg2+ 20mmol slow boluses
Fluid and electrolyte therapy should now ideally be guided by frequent monitoring, not
theoretical calculations / protocols.
Other therapy
Give 5000U SC heparin bd unless contraindicated as the risk of DVT/PE is very high
Consider antibiotics if infectious cause suspected.
Sodium bicarbonate is not indicted to reverse the acidosis, with the possible exception of when
the pH remains <6.90 despite therapy.
Consider 50-100ml of 8.4% NaHCO3 if the initial K+>6.5, along with 10ml 10% Ca
gluconate, noting that K+ is still likely to require replacement once insulin is effective.
.
Suggested medications
Actrapid infusion
MgCl2
Na/K H2PO4
Heparin
Consider antibiotics.
eg. ceftriaxone
5-10 U / hr – aim to reduce glucose by
10-20mmol
10-20mmol
5000U SC
1g IV daily/bd
Specific Advice
Normalisation of BSL is not an indication to stop
the insulin/dextrose infusion, as insulin/dextrose is
required to clear the ketoacidosis, which does not
parallel improvement in the BSL. Continue
insulin/dextrose until ketones clear – which will
usually be at least the day after presentation.
A CVC or arterial line is likely to be
needed for frequent blood monitoring. If
peripheral IV access difficult, pt. has
contraindication to an arterial line,
volume status is particularly difficult to
assess or MAP < 65 – start with CVC.
Otherwise start with an arterial line.
Retrieval issues
Use the iStat for monitoring during prolonged
transfers
Ensure there is a CVC or arterial line in
place prior to a prolonged transfer to
allow access to blood samples
125
Intra­aortic Balloon Pump This document outlines the basics of IABP technology and its use in the retrieval
environment.
All IABP retrievals will be done with a perfusionist (technician) and retrievalist. The
Perfusionist brings the machine and manages the pump and circuit leaving the retrievalist to
manage the patient. A good working relationship between retrievalist and perfusionist should
be established early in the mission. Many of the perfusionists are used to travelling with fairly
junior cardiology registrars who have little familiarity with the transport environment.
What is an IABP?
The IABP is a long balloon over a catheter which is placed in the aorta, ideally just distal to
the left subclavian artery and proximal to the renal arteries. It is usually inserted femorally
although can be inserted from a brachial approach. A percutaneous Seldinger technique is
used, generally with fluoroscopic guidance in an angio suite although blind insertion with X
ray for confirmation of position is possible. The catheter has two lumens, one to measure
aortic pressure and one to inflate and deflate the balloon. The balloon is filled with helium gas
from a small tank on the pump and inflation-deflation is timed with the cardiac cycle. Helium
is used because of its flow characteristics allowing very rapid and precise inflation and
deflation.
How is it timed?
The balloon inflates in diastole, just prior to the dichrotic notch. The second peak after the
dichrotic notch, is the result of closure of the aortic valve and muscular and elastic recoil of
the aorta against the closed. The balloon deflates at the onset of systole. As it happens the
point “just prior to the dichrotic notch” corresponds to the mid-T wave and the beginning of
systole to the peak of the R wave.
Timing, therefore, can be achieved by computer recognition of ECG features (ECG peaks,
ECG shapes or patterns, atrial pacing spikes or ventricular pacing spikes), by fluctuations in
aortic pressure measured at the catheter tip or by an intrinsic, machine-generated rhythm in
case of cardiac arrest).
The machines used by Perfusion Services Australia have an Autopilot mode that
automatically selects the best timing mode for the conditions.
How does it help?
By inflating in diastole with a competent aortic valve the balloon displaces blood from the
aorta increasing forward flow during diastole when it would normally diminish and increasing
coronary perfusion by increasing diastolic pressure without any increase in intra-cardiac
pressure (although empirical evidence of the latter effect is less convincing). By deflating just
before the aortic valve opens again it decreases left ventricular afterload by presenting the left
ventricle with a relatively empty aorta to pump into. This means the left ventriclular wall
tension is lower as are left ventricular and left atrial end diastolic pressures which means a
reduction in preload. Stroke volume and cardiac output increase and myocardial oxygen
consumption decreases.
The pump can be used on every cardiac cycle or on a fraction of them. It must inflate on at
least 1 in 8 cycles to prevent thrombosis. Increasing the frequency of cycling will increase the
126
degree of help provided to the cardiac output. During weaning the cycling ratio is decreased
gradually
What will the blood pressure do?
So, you thought blood pressure was two numbers with a oblique line in between them (and
another in brackets if you are an intensivist)? Not once you have two pulsation pumps (heart
and IABP) working in series.
Figure 1. IABP cycling 1:2
In figure 1 the IABP is set to cycle 1:2, that is to say, the balloon inflates on every second
cardiac cycle. The first wave is a normal heartbeat without the IABP activating. There is a
systolic pressure (now called unassisted systole), a dichrotic notch and diastolic pressure (now
called an unassisted aortic end diastolic pressure). The IABP inflates after the next systole so
the next systolic pressure is another unassisted one. Diastole, however, is very different this
time. Note that the Augmented diastolic pressure is quite high, higher than systolic pressure
and that it is followed by a Assisted aortic end diastolic pressure which is lower than the
unassisted one (because of the effect of sudden evacuation of the aortic contents). Following
that there is another “normal” beat only this one is not normal because the ventricle is
benefiting from the decreased afterload that results from the lower assisted aortic end diastolic
pressure. This is, therefore an assisted systolic pressure.
So, with the IABP cycling 1:2 we have an unassisted systolic pressure, an augmented diastolic
pressure, an assisted end diastolic pressure, an assisted systolic pressure, an unassisted
diastolic pressure and then an unassisted systolic pressure again.
Thankfully the machine will report the mean arterial pressure making the task of keeping a
sensible obs chart somewhat easier.
Note though that the assisted pressures should be lower than the unassisted ones or will be in
patients who were relatively normotensive at the outset. In patients with hypotension an
increase in MAP will result as the increase in pressure during diastolic augmentation is
greater than the decrease in pressure during assisted systole and diastole.
When is it used?
• Cardiogenic shock
127
Ischaemic contractile failure- majority of cases, obvious benefits from
decreased preload and afterload and augmented pumping.
o Acute MR or ventricular septal rupture- leads to significant decrease in
backflow (MR) or left to right shunt (VSR).
Intractable angina
o Weaker indication, probably helps
High risk CABG peri-procedure
o Decreases time on bypass and post-op IABP time
High risk cardiac cath
o Weakest indication but may be beneficial should procedure related ischaemia
occur (e.g. in tight left main stenoses)

Contraindications
• Aortic regurgitation
o IABP relies on a competent aortic valve. In AR the IABP will cause
increased regurgitation and increased intracardiac pressures and wall tension,
the reverse of what it aims to do.
• Aortic dissection
o Risk of placement in a false lumen and aortic rupture
• Aortic aneurysm (large)
o Risk of rupture
• Severe peripheral vascular disease preventing insertion
• Uncontrolled septicaemia
• Uncontrolled bleeding diathesis
What could possibly go wrong?
• Vascular
o Bleeding
o Thrombosis
o Embolisation
o Limb ischaemia
o Infection
o Aortic branch vessel occlusion (particularly spinal arteries)
• Mechanical
o Balloon rupture
o Inadequate inflation
o Inadequate augmentation
o Catheter displacement or damage due to patient movement
• Haematological
o Thrombocytopenia and anaemia are common due to mechanical destruction
o Complications of heparinisation may occur
• Underlying disease may progress in spite of IABP.
Deaths from IABP are rare and mainly related to aortic dissection or rupture.
What do you need to check?
• Ensure you are clear about:
o The indication for insertion of the pump
o The response to treatment
o The rate of cycling, why this rate has been chosen and whether it has changed
since insertion.
ƒ Minimum rate to avoid thrombosis is 1:8
ƒ If cardiac output is inadequate rate can be increased as far as 1:1.
• Check with the perfusionist that the technology used at the referral site, their
technology to be used in transit and that which is likely to be used at the destination

site are going to be compatible. In general the machines used by PSA for transport are
able to be adapted to lines made for other machines.
Insertion site for haematoma, bleeding, adequacy of dressings and inflammation
Position
o Ensure you have seen radiological confirmation of the position. A CXR
should demonstrate a radio-opaque catheter tip at the top of the ascending
aorta.
o If it has been inserted fluoroscopically ask for a copy of the still images to
take with the patient or get a CXR taken before departure as evidence of
correct position
Heparin infusion rate and APTT if done already.
Patient comfort
o Patients need to lie flat and not move the affected limb for the duration of the
time the IABP is in. This necessitates good analgesia and often sedation,
especially when the patient is on a transport stretcher. In the aeromedical
transport environment this may require intubation in some cases. This should
be born in mind when coordinating IABP transfers from CCU to CCU.
Timing (see Figure 2 below)
o This is primarily the realm of the perfusionist however these are the things
that are considered. The key to assessing timing is assessment of the aortic
pressure waveform which is displayed on the machine monitor.
o Basically, the balloon can inflate too early (B) or too late (C) and can deflate
too early (D) or too late (E) ((A) is normal).
Figure 2. Timing issues with IABP
ƒ
ƒ
ƒ
ƒ
Early inflation (B) (before aortic valve closure) causes increased afterload and myocardial
oxygen consumption with the ventricle contracting against an inflated balloon.
Late inflation (C) occurs when the aorta pressure has already dropped off so there is less
potential for diastolic augmentation.
Early deflation (D) shortens the period of diastolic augmentation and may result in
backflow from coronaries and carotids.
Late deflation (E) has the same consequences as early inflation.
129
What about the hardware?
PSA use Arrow machines distributed in Australia by Mayo Healthcare. The two machines are
Autocat 2 Wave and ACAT 1.
The Autocat Wave 2 is pictured above. The display and control unit on top comes off the unit
and can sit on the lap of the perfusionist with a wired connection to the pump unit which
needs to be stowed securely. In Victoria CPAV should be used for IABP retrievals. NSW
ambulance services have a vehicle in each region that is purpose built to carry an IABP
patient with a lifter and docking area for the pump at the rear of the vehicle.

Interventions
Ventilation targets :
PaO2 > 100, PaCO2 approx. 35, avoid excessive PEEP (but PEEP is a secondary consideration
to adequate oxygenation)
Blood pressure control :
Manage hypertension on an individual basis with advice from receiving neurologist/surgeon
There is no definitive evidence however current ASA/AHA guidelines suggest that if SBP is >
180 or MAP is >130 then lowering of BP to a MAP of 110 or target BP of 160/90 using
intravenous medications is probably safe.
Anticonvulsant therapy :
Clinical seizures should be managed agressively using benzodiazepines.
Patients who have seized or who are showing evidence of seizure activity on EEG should be
propylactically loaded with :
Dilantin – 20mg/kg (if not already taking)
Other measures :
Elevate head 30 degrees
Control hyperglycaemia with insulin infusion

Retrieval issues
Protect against secondary brain injury from hypoxia, hypotension and hyperglycaemia
Arrange to take Prothrombinex to patient if not available in referral hospital
Discuss use of Mannitol with receiving neurologist or surgeon before departing referral
hospital.
Steroids are not indicated in ICH
Consider inserting CVC and arterial line to monitor / control BP. Mandatory if patient is
intubated.
Avoid hypotonic IV fluids (ie. 5% Dextrose, Hartmann’s solution) ; use plasmalyte or 0.9%
saline.
iStat useful to monitor ventilation and BSL on long transfers. ETCO2 may not be an accurate
guide to PaCO2, and at the very least the relationship betwen the two should be defined once
prior to transfer.
Even if prognosis is thought hopeless and transfer for surgery is not indicated, retrieval may
still be warranted to facilitate organ donation if the NOK agree.

inflate the lungs. The danger of barotrauma is minimized by the fact that most of the excess
pressure is directed towards opposing the additional abdominal girth during lung inflation.
The maximum 400 joules of energy in regular defibrillators is sufficient for the morbidly
obese. Although higher transthoracic impedance from chest wall fat may occasionally make
defibrillation difficult, the chest wall is usually not much thicker in most obese patients.
Pharmacology/Weight‐Based Dosing Highly lipophilic substances such as barbiturates and benzodiazepines, show significant
increases in volume of distribution (VD) for obese individuals relative to normal-weight
individuals Less-lipophilic compounds have little or no change in VD with obesity. Certain
exceptions to this rule include digoxin, procainamide , and remifentanil, which are highly
lipophilic drugs but which have no systematic relationship between their degree of
lipophilicity and their distribution in obese individuals. Consequently, their absolute VD
remains relatively consistent between obese and normal-weight individuals, and their doses
should be calculated on the basis of ideal body weight.
Drugs with weak or moderate lipophilicity can be dosed on the basis of ideal body weight
(IBW) or, more accurately, lean body mass (LBM). These values are not identical, because
20%–40% of an obese patient’s increase in total body weight can be attributed to an increase
in LBM. Adding 20% to the estimated IBW dose of hydrophilic medications is sufficient to
include the extra lean mass. Nondepolarizing muscle relaxants can be dosed in this manner.
The majority of anesthetic drugs are strongly lipophilic. Increased VD is expected for
lipophilic substances, but this is not consistently demonstrated in pharmacological studies
because of factors such as end-organ clearance or protein binding.
Weight-Based Dosing of Common IV Anaesthetics
Drug Propofol Dosing IBW
Maintenance:
TBW
Comments Systemic clearance and Vd at steady-state correlates well
with TBW (92). High affinity for excess fat and other well
perfused organs. High hepatic extraction and conjugation
relates to TBW.
TBW
Increased Vd. Increased blood volume, cardiac output, and
Thiopentone muscle mass (91). Increased absolute dose. Prolonged
duration of action (93).
TBW
Central Vd increases in line with body weight. Increased
Midazolam absolute dose. Prolonged sedation because larger initial
doses are needed to achieve adequate serum
concentrations (93, 94).
Plasma cholinesterase activity increases in proportion to
Succinylcholine TBW
body weight. Increased absolute dose (93).
IBW
Recovery may be delayed if given according to TBW
Vecuronium because of increased Vd and impaired hepatic clearance
(93, 95).
IBW
Faster onset and longer duration of action.
Rocuronium Pharmacokinetics and pharmacodynamics are not altered
in obese subjects (96, 97).
TBW
Absolute clearance, Vd, and elimination half-life do not
Atracurium change. Unchanged dose per unit body weight without
Cisatracurium prolongation of recovery because of organ- independent
elimination (98, 99).
TBW
Increased Vd and elimination half-time, which correlates
Fentanyl positively with
IBW = Ideal body weight; TBW = Total body weight; Vd = volume of distribution. 135
The morbidly obese are vulnerable to both pressure areas and thromboembolic complications.
Appropriate precautions should be taken.
Transport Platform Options General considerations
Morbidly obese patients need to be considered both in terms of their weight as well as their
physical dimensions, particularly width. A patient who is oversized for a stretcher may fall
off, develop pressure wounds, or make ongoing management impossible. If there is too much
“overhang” from the patient’s arms over the side rails, then this can also be a problem when
stretchers fit tightly against a wall such as in all AAV helicopters and HATS vehicles.
In general, a patient approaching 160kg will not fit on a standard ambulance stretcher because
of width rather than weight and should be considered for CPAV. A patient between 120 and
160kg should be carefully considered regarding platform selection. AAV fixed wing is
limited to 120kg.
Example: A 70year old 130kg, 160cm (5 ft 3 in) tall female only just fits on a standard
ambulance stretcher in HEMS 4 (with difficulty and after some equipment rearrangement).
This is due to both stretcher handling difficulty/pressure care/won’t fall off, but more because
the patient’s arms and body overhanging the stretcher edge won’t fit against the engine wall
and therefore the stretcher can’t be rolled in. A 180cm (6 ft) person of the same weight is
likely to fit with relative ease.
Road
“Emerg Cars”
All AV emergency ambulance vehicles have had stretchers upgraded to a 230kg capacity.
These stretchers are FERNO 50E brand and have green/yellow fluorescent legs.
The distance between the two side rails is 49cm. It is not uncommon to transport obese
patients with the torso/abdomen within the side rails but the arms (and some adipose tissue)
overhanging them and strapped in.
CPAV (Complex Patient Ambulance Vehicle)
There are 5 of these vehicles in Victoria:
Metropolitan Melbourne x2 (although usually one per shift)
Geelong x 1
Sale x 1
Bendigo x 1
They have specialised equipment for moving very large patients on a wide stretcher. They
have the ability to weigh their patients and have a stretcher capacity of 450kg.
Their largest clients in Victoria are around 330kg and these patients overhang their wide
stretcher.
HATS
Use the same FERNO 50E stretchers as the rest of AV – 230kg capacity,
Fixed Wing
Victoria
The capacity of the RFDS Super King Air in use at AAV is limited to 120kg by the lifting
mechanism on the aircraft. This means a 120kg patient plus equipment can be safely lifted.
NSW
RFDS standard planes have a capacity to lift 140kg without equipment or a bridge. There is a
plane based in Dubbo that has a capacity of 180kg (without equipment).
136
South Australia
MedSTAR’s RFDS planes can transport up to 180kg on their stretchers if the side rails can be
locked in the upright position.
Rotary Wing
AAV HEMS 4 & 5
These two aircraft are identical and employ a roll on roll off mechanism using standard
ambulance stretchers. This is limited to the 230kg limit of the stretcher. The size of the
patient on a standard stretcher is likely to limit this option rather than weight restrictions as
above.
AAV HEMS 1,2 & 3
These aircraft involve the litter (top part of the standard trolley) being manually lifted off the
stretcher legs and into the aircraft. The litter used by AV is a FERNO 155-E which has a
carrying capacity of 159kg when not on stretcher legs.
All patients greater than 120kg must be discussed with the flight coordinator to determine
appropriateness for RW transfer.
Bariatric Imaging Options CT
In general CT is logistically possible for many morbidly obese patients. Most patients will
have a CT scanner within their local area with a table capacity around 220kg.
The myth that there is an enormous elephant sized scanner at Werribee Zoo (or any other zoo)
is just that – a myth. Veterinarians do use CT (and sometimes put a horse leg or smaller
animals into it) but these are the same as the CT scanners made for the rest of the medical
industry.
MRI
The width of the patient is the rate limiting step for MRI in morbidly obese patients rather
than table capacity. The hardest part of the patient to get into the scanner is usually the
shoulder/arms where the patient often has to get them above the head to enter the scanner.
There are several “wide bore” 70cm MRI in metropolitan Melbourne which may be able to
accommodate larger patients.
There is an “open” scanner at Radar Medical Imaging in Bundoora which is mainly for
claustrophobic patients where patients do not get the medicare rebate. It has two plates above
and below the patient 33cm apart that the patient has to fit though. The table has a weight
limit of 170kg. Most morbidly obese patients have an AP thickness of greater than 33cm but
this scanner may be useful if only required to get a head or a neck into the scanner but would
be logistically challenging and require further clarification.
