If you are unsure about them after reading this, please speak to your Homecare Technician or a Customer Services Representative who will be only too pleased to explain these safety rules to you. General Information Oxygen for Medical use Higher Oxygen Concentrations Mean Greater Risk Fire Triangle Oxygen is a colourless and odourless gas, so the normal human senses cannot detect if there is more oxygen than normal in the surrounding air. Oxygen can build up and concentrate in a closed room or a confined space, but it can easily be dispersed in a well ventilated room. To start a fire, three things are needed, something to burn (fuel), something to set it alight (heat or a spark) and oxygen to support the fire and keep it going. Oxygen can build up unnoticed on your clothing and in your hair as you breathe it, even while you sleep and use oxygen, your bedding can become saturated. For this reason, home oxygen users are always at risk from their clothing, bedding, furniture and their hair catching fire as a result of smoking or others in close proximity to them smoking. Oxygen makes up 21% of the air that we breathe, oxygen is an oxidizing agent which means that it helps things burn more easily and more fiercely. Home oxygen users MUST NOT smoke or allow others to smoke where oxygen is being used. In oxygen enriched atmospheres, fabrics, wood, paper and other materials, which normally do not burn easily in air may suddenly catch fire on contact with a small spark, cigarette or naked flame. Fatty substances, oils and greases may spontaneously ignite in oxygen. Home Oxygen Users MUST NOT smoke or allow others to smoke where oxygen is being used. 3 Section 1: Safety Fire Risks Materials burn much faster in oxygen than in air alone. G NEVER smoke or let anyone else smoke near you while you are using your medical oxygen equipment G DO NOT use your medical oxygen equipment near open fires or naked flames G In the event of a fire and providing it is safe to do so, ring 999 and ask for the Fire Service G Advise the Emergency Operator that there is oxygen on the premises G When possible ring Air Liquide and advise them what equipment was involved in the fire G Any items that have been involved in a fire or accident MUST NOT be used Storage & Use Always follow the advice given to you by your Homecare Technician as to the safest place to store and use your medical oxygen equipment. G Ensure that all your equipment is stored in a well ventilated area, kept clean, dry and away from any sources of heat or fire G The storage area SHOULD NOT be used to store paint, oil, Keep equipment upright grease or any domestic heating gases G DO NOT keep combustible materials near your medical oxygen supply G When storing your cylinders they should either be laid down flat or secured upright to prevent them falling over G Your medical liquid oxygen base unit MUST always be stored upright 4 Section 1: Safety Oxygen Saturation Materials will become saturated or enriched with oxygen if your equipment leaks and will burn very fast if ignited. Only use or store your medical oxygen equipment in a well ventilated area. Keep all internal doors open while your oxygen is in use. G NEVER place your medical oxygen equipment near curtains or cover it with coats or other such materials as this will restrict the air circulation G NEVER leave your cannula or mask on the bed or chair whilst the oxygen is on G TURN OFF your medical oxygen supply when you are not using or have finished with it G NEVER carry or use a portable medical oxygen source under clothing Oils & Grease G DO NOT use oils or grease with your medical oxygen equipment G Make sure your hands are clean and that you use only recommended creams or moisturisers when using your medical oxygen G DO NOT use aerosol sprays such as hair sprays or deodorants when using your medical oxygen equipment G UNDER NO CIRCUMSTANCES should products such as Vaseline and E45 cream be used to soothe a sore around your nose or mouth when using your medical oxygen, you must only use something similar to K-Y jelly as this is a water based product and is completely safe for use with medical oxygen. If you are unsure please ask your Doctor or Pharmacist Cold Burns Manipulating medical liquid oxygen can cause cold burns, please refer to Section 4 - How to use your Medical Liquid Oxygen. 5 Section 1: Safety Connecting your Tubing 15 metres max. Connecting your tubing to a medical oxygen supply system is very easy. Your Homecare Technician will show you how this is done when he or she installs your equipment. Tubing over 15 metres long MUST NOT be used as this will reduce the flow. Take care with any tubing laying on the floor and ensure that it is not trapped under doors, chairs, or heavy items of furniture, and that it is not allowed to kink. Flow Rate - Litre Per Minute (LPM) Your flow rate has been prescribed by your Doctor or Nurse and must not be changed without asking them first. G Homecare Technicians ARE NOT allowed to set your medical oxygen flow rate to anything other than that prescribed G Before opening the flow valve, make sure that the flow rate indicator is set to zero G Open the flow valve slowly by turning it anti-clockwise and then set the flow meter at the flow rate prescribed by your healthcare professional G Check for leaks on the connections after opening the valve. Your Homecare Technician will show you how this is done G You can check for a flow by placing the end of the tube in a glass of water and watch for bubbles. DO NOT place the end of your cannula in the water 6 Section 1: Safety Medical Oxygen Supply G Check on a regular basis that there is an adequate supply of oxygen in your medical oxygen equipment by checking the gauge on your medical oxygen cylinder or on your medical liquid oxygen units G NEVER allow your medical oxygen cylinder or medical liquid oxygen base unit to completely empty G ALWAYS close the valve on your oxygen supply when you are not using your medical oxygen G It is natural for medical liquid oxygen to evaporate, but this happens very slowly from the base unit and you should not run out if you check the contents on a regular basis Cleaning G Use only a clean damp cloth to clean your medical oxygen equipment G Use only mild non-abrasive cleaning materials G Always allow your equipment to dry after wiping it down before using Repairs G Should your medical oxygen equipment fail for any reason call the Customer Services Helpline on 0808 143 9999 immediately G NEVER attempt to repair or modify any fault unless instructed to do so by a qualified Homecare Technician G Air Liquide cannot be responsible for accessories that you attach to your equipment if they have not been supplied by us NEVER attempt to repair or modify any fault unless instructed to do so by a qualified Homecare Technician. 7 Section 2: Concentrators What is a Concentrator? An oxygen concentrator is a machine that separates oxygen from other gases that are present in the surrounding air. Air is made up of 79% nitrogen and 21% oxygen and minute traces of other gases. The concentrator draws air from the room and separates oxygen from the other gases using a filtration system. The filter traps most of the other gases and allows oxygen to pass through. Oxygen can now be delivered to you by way of tubing to your cannula for you to breathe. Other people in the room will still be breathing normal amounts of oxygen present in atmospheric air. The concentrator operates with electricity and uses approximately 280 watts of power. This may vary depending upon the flow rate that is prescribed for you. It will make a slight humming sound very much like that of a refrigerator. Parts of the Concentrator Main Flow Control (lpm) Oxygen Outlet Purity Warning Light Hour Meter On/Off Switch 8 Section 2: Concentrators How do I use my Concentrator? Using a concentrator is very simple. Your Homecare Technician will talk you through all the following steps during the installation: 1. Insert the power plug into a power outlet source/mains socket and switch ON. 2. Attach the tubing from your cannula to the outlet connection on your concentrator. Tubing over 15 metres long MUST NOT be used because this will reduce the flow (Refer to Fig. 1). Fig. 1 3. Locate the ON/OFF switch on the front of your concentrator (Refer to Fig. 2). 4. To turn your concentrator ON press the button up (I). An alarm will sound for approximately five (5) seconds and then stop, this is a normal event and indicates that the alarm is working correctly and that the battery is in full working order (Refer to Fig. 2). ON OFF Fig. 2 5. Turn the adjustment knob anti-clockwise until the ball reaches the prescribed flow rate (Refer to Fig. 3). 6. Check that there is a flow of oxygen from your equipment. This can be done by placing the end of the tube in a glass of water. If there is a flow you will see bubbles coming from the end of the tube (Refer to Fig. 4). 7. If there is no flow, please contact the Customer Services Team on 0808 143 9999. 8. In the event of a power failure, you have been provided with a back-up cylinder which must be used only for this purpose. The back-up cylinder should not be used as a main oxygen supply. Fig. 3 Fig. 4 Before you use your equipment make sure that you have read the safety information in Section 1 of this guide. 9 Section 2: Concentrators After using your Concentrator OFF Fig. 5 1. When not using your concentrator flick the power switch to the OFF (O) position (Refer to Fig. 5). 2. If you are not going to use your concentrator for an extended period of time, you are advised to switch your unit off at the mains socket. Looking after your Concentrator Before carrying out any of the following maintenance tasks on your concentrator, PLEASE READ THE SAFETY INFORMATION IN SECTION 1 OF THIS GUIDE. 1. Clean the cabinet occasionally with a damp cloth and then wipe it dry. Avoid letting water into the internals of your concentrator. DO NOT use any detergents or abrasives when cleaning the unit. 2. Wash the filter from the unit at least once a week. G Remove the filter and replace it with the spare filter G Hand wash the filter in warm soapy water G Rinse it thoroughly and remove any excess water with a clean absorbent towel G Allow the filter to dry naturally, and put it in a safe place until you change the filter again 3. If you have a humidifier fitted you must change the water on a daily basis. 4. Wash the humidifier bottle once a week. G Wash the bottle with warm soapy water G Rinse thoroughly with clean water G Dry the outside of the bottle with a clean absorbent cloth G Refill the bottle with distilled water If you run out of distilled water, use boiled water that has been kept in a covered container and allowed to cool. 10 Section 2: Concentrators Servicing The concentrator that you have been provided with will give you a constant supply of oxygen 24 hours per day every single day of the year. Your Homecare Technician will visit every six (6) months to carry out maintenance on your concentrator. Concentrator Attachment Oxygen Outlet A member of our Customer Services Team will contact you in advance to advise you when this routine maintenance will take place. During a maintenance visit the Homecare Technician will: – check that the tubing is in good condition, – check that your back-up cylinder(s) are full and working properly, – supply you with new cannulae and any other consumables that you may need. Fig. 6a Humidification Few home oxygen users require humidification. However, if it has been prescribed for you, there are a few simple steps for you to follow: 1. Unscrew the top of your humidifier bottle and fill with distilled water. NEVER fill the bottle above the line indicated. 2. Screw the top of your humidifier bottle back on. 3. On the top of the humidifier bottle you will see a threaded nut. Screw the humidifier onto the concentrator and secure tightly. Make sure you do not cross thread or over tighten your humidifier bottle (Refer to Fig. 6a). Fig. 6b 4. Attach your short tube to the oxygen outlet on the humidifier bottle (Refer to Fig. 6b). Attach the water trap to the other end (Refer to Fig. 7). Place it lower than the humidifier bottle.

Section 2: Concentrators Electricity Rebates We will make a payment to you every three (3) months estimating the costs of running your concentrator according to the prescription supplied by your Doctor or Healthcare Professional. Hour Meter Every six (6) months during the routine maintenance visit, the Homecare Technician will take a reading and record the hours that your concentrator has been used. This reading will enable us to calculate the electricity that has been used to run your concentrator and we will send you a payment to cover these costs. We will take into account any under or over payment that has been made to you as a result of the three monthly estimate. Payments are usually issued in the patient’s name, but we can change this for you if this is not convenient. You will need to advise us by completing an Electricity Application form and return it to us in the Pre-Paid Envelope provided. If you are concerned about your electricity reading, you can take a reading for yourself and call the Customer Helpline and speak to our Accounts Team who will gladly discuss your reading with you. On/Off Switch The meter is located on the front of the concentrator, just below the serial number (Refer to Fig. 8). To read your meter on the concentrator turn your head so that it touches your left shoulder. You can now read the number correctly: this number is the number of hours that your concentrator has been operating (32 hours shown in Fig. 8).

You will be able to use the Freestyle™ in the car as you travel; this concentrator can also be used on some airlines for travel abroad, but you are advised to check with your airline before starting your travel arrangements. The use of this portable concentrator is unlimited for those patients who have been assessed by a Respiratory Doctor or Respiratory Nurse Specialist. Only they will be able to determine if the Freestyle™ Portable Concentrator will fulfil your ambulatory needs. 17 Section 2: Concentrators The Sequal Eclipse® Transportable Concentrator At about the same size as a small travel case, the Sequal Eclipse Transportable Concentrator will be the answer to most patients’ travel problems. The Eclipse has a flow rate of up to 3 litres per minute on constant flow and a flow rate of 1 – 6 litres per minute when used on demand or in the pulsed dose mode. To save the waiting for cylinders when you arrive at your holiday destination and the worry of carrying additional cylinders for your return journey, Air Liquide can provide the Sequal Eclipse Transportable Concentrator for travel to those patients for whom it is found suitable following consultation with your Respiratory Doctor or Respiratory Nurse Specialist. The Eclipse means extended travel without the fear of running out of oxygen. Just plug the Eclipse into your car accessory (cigarette lighter) outlet and go as far and as long as you like. By Air The Eclipse has been approved for use on most commercial airlines. However, each airline company has different rules so you are advised to check with your carrier before you fly to avoid disappointment. By Train Most intercity trains within the UK now have a power outlet by the window seats, so you can use the Eclipse without fear of running out of oxygen during your journey. Cruises The Eclipse has proven very popular on cruises as it will give you freedom to roam around your cruise liner and visit the ports of call without the fear of running out of oxygen. 18 Section 2: Concentrators Typical Duration of Use FLOW SETTINGS LITRES PER MINUTE CONTINUOUS FLOW MODE DURATION 0.5 1.0 2.0 3.0 4.0 5.0 6.0 4.4 3.7 2.4 1.3 hours hours hours hours PULSE FLOW MODE DURATION 4.4 3.6 3.0 2.6 2.3 2.1 hours hours hours hours hours hours Equipment Specification Size Weight Sound Level 19.3 high, 12.3 wide, 7.1 deep 7.9kg (17.4 lbs) with battery installed 48 dB at 3.0 LPM Continuous Flow 40 dB at 3.0 LPM Pulse Flow Setting 19 Section 3: Medical Oxygen Cylinders The Basics Medical oxygen cylinders have a black body and a white shoulder and are fitted with an integral valve and dial select flow control knob which is ready and easy to use. NEVER use cylinders that are not correctly labelled. Medical oxygen cylinders will ALWAYS display a label confirming that they contain ‘Medical Oxygen’. A white plastic guard protects the valve against accidental damage and must NEVER be removed. Medical oxygen cylinders contain gas at a very high pressure of between 200-230 bar at a temperature of 15°C. This pressure is some 115 times greater than the typical pressure in the tyres on a car which are only 2 bar. All cylinders supplied by Air Liquide have integral regulators, your Homecare Technician will show you how to use this and will point out the various controls. 20 Section 3: Medical Oxygen Cylinders How do I use my Medical Oxygen Cylinder? (Refer to Fig. 9) 1. Ensure the flow meter is set to (0). 2. Attach the tubing and cannula to the oxygen outlet. 3. Check the contents gauge to ensure that the cylinder contains oxygen. Slowly turn the ON/OFF knob located on the side of the cylinder anti-clockwise to fully open. 4. Turn the flow control to the prescribed flow rate which is indicated below the flow control knob. 5. Check for leaks on the tubing connection. 6. Check for flow from the cylinder. 7. If there is no flow, check that your cannula is not blocked. After Use Oxygen Outlet 1. Turn the ON/OFF knob clockwise to close hand tight. 2. A hissing sound may be heard for a few seconds whilst the residual gas is released. 3. Wait until all of the residual gas has stopped flowing and then turn the flow control knob to the (0) position. Flow Selector Knob Fig. 9 Changing a Cylinder 1. Ensure that the ON/OFF knob of the empty cylinder is fully closed. 2. Detach your tubing and cannula from the oxygen outlet on the cylinder regulator. 3. Now follow the ‘How do I Use My Medical Oxygen Cylinder’ instructions as detailed earlier.

This information is only for guidance and is not an accurate calculation but it will give you some very useful information and assist you to determine how long your medical oxygen supply will last you at your prescribed flow rate. If you need more medical oxygen, please remember to call us at least three working days in advance and before 5:00pm so that your next delivery can be scheduled. 24 Section 3: Medical Oxygen Cylinders 2 Pressure (Bar) Cylinder Size (Litre) 2 2 2 230 230 230 200 230 M02HQL HC02HQ HC02H HC02M HC10H HC104C 35.4 40.7 17.7 20.4 Duration (Hours) 0.25 32.6 0.5 16.3 0.75 10.9 7.08 8.14 8.14 1.5 2.0 10 200 Flow Setting 1.0 10 8.14 5.43 3.54 4.07 4.07 2.5 4.07 3.26 3 2.36 2.71 2.71 2.71 11.8 13.6 4 1.77 2.04 2.04 2.04 8.85 10.2 5 1.42 1.63 1.63 1.63 7.08 8.14 6 1.18 1.36 1.36 1.36 5.9 6.79 7 1.01 1.16 1.16 5.06 5.82 8 0.89 1.02 1.02 4.43 5.09 0.71 0.81 0.81 3.54 4.07 0.59 0.68 0.68 2.95 3.39 0.47 0.54 0.54 2.36 2.71 9 10 11 12 13 14 15 25 Section 4: Medical Liquid Oxygen Useful Information: G 1 litre of medical liquid oxygen will ‘evaporate’ as it warms up to provide 860 litres of oxygen gas. G A typical portable 0.8 litre medical liquid oxygen unit contains about 688 litres of oxygen gas. G A typical base unit will hold approximately 26,660 litres of oxygen gas. That is the equivalent of having 55 portable cylinders ‘on tap’. Lighter medical liquid oxygen portable units provide you with excellent mobility. G A medical liquid oxygen base unit takes up less floor space than 4 standard 10 litre medical oxygen cylinders. This makes it a highly efficient method of storage and supply. G Home oxygen users / their carers may refill the portable units directly from the base unit as and when required. G Portable medical liquid oxygen units may be carried over the shoulder or worn across the chest using the strap provided. IMPORTANT! Safety information for medical liquid oxygen In the unlikely event of a leak from the base unit, wheel the base unit outside. If possible, open the doors and windows for ventilation and allow the oxygen to disperse. In the event of accidental contact with the skin G DO NOT rub G Remove any clothing if necessary and gently apply slightly warm water for at least 15 minutes G Call your Doctor 26 Section 4: Medical Liquid Oxygen What is Medical Liquid Oxygen? Medical liquid oxygen is stored in an insulated stainless steel container similar to a thermos flask. These storage containers are referred to as base units and they hold the medical liquid oxygen at an extremely low temperature. Medical liquid oxygen base units are low pressure storage containers designed to safely store more oxygen than gas cylinders can. The temperature of liquid oxygen is -183°C and can cause serious ‘cold’ burns if it should ever come into contact with your skin. A medical liquid oxygen system that is installed in your home will generally consist of a base unit mounted on a roller base with a separate portable unit similar to the ones shown (Refer to Fig. 10). Medical liquid oxygen systems are installed to meet portable oxygen requirements outside the home. If you have been supplied with an oxygen concentrator for use in the home, you MUST NOT use your medical liquid oxygen system for this purpose. Fig. 10 In the event of a power or concentrator failure, the medical liquid oxygen base unit, in conjunction with the portable unit, may be used as a temporary back-up supply until the concentrator or electricity supply has been repaired or restored. 27 Section 4: Medical Liquid Oxygen 5a How to use your Medical Liquid Oxygen Your portable medical liquid oxygen unit should only be used for your active use and not for storage. You should fill your portable unit about 15 minutes before you intend to use it, this will maximise the time available when you do go out. 5b 1. Wash your hands before handling any oxygen equipment. 2. Wipe both blue filling connections with a dry lint free cloth. The blue connections are located as follows, one on top of the base unit and the other on the base of your portable unit. These two connections must be clean and dry to prevent ice formation during filling. 3. NEVER try to fill your portable unit if your base unit is empty. 4. Turn the flow rate selector on your portable unit to (0). 5a. Hold the portable unit in both hands and then position the two blue quick release connectors together, one is on the base unit and the other is on the bottom of the portable unit and press down firmly with two hands. 5c 5b. Begin filling the portable unit by simply pressing down the vent valve handle into the open position while continuing to apply downward pressure on the portable unit to maintain a connection. When the portable unit starts to let out vapour and sounds as if it is ‘spitting’ it is full and you should close the valve. 5c. When disconnecting the portable unit, simply depress or push the grey disconnect plunger on the base unit, this will disengage your portable unit from the base unit. If the portable unit freezes to the base unit, simply close the vent valve handle and leave it attached. Once the connections have thawed out in about 10-15 minutes the units can be easily disengaged. 28 Section 4: Medical Liquid Oxygen 5d. To check the contents hold the strap as shown in picture 5d. The bar as in 5e will show a green zone indicating how much liquid oxygen you have in your portable unit. 6. Never touch the blue quick release connectors after filling, as they are very cold and will cause cold burns. 7. Connect the cannula to the oxygen outlet on your portable unit. 8. Using the flow rate selector on either the top or front of the portable unit set this to your prescribed number (litres per minute). This is the flow rate prescribed by your Healthcare Professional. 5d Take care that the flow rate selector has been set properly and is not set in between two correct settings, if this is the case then your oxygen will not be able to flow. The above filling guide is only a quick reference guide. For further information regarding your particular medical liquid oxygen system, please refer to the ‘Manufacturers Patient Handbook’ that your Homecare Technician has provided you with. 9. 5e The medical liquid oxygen in your portable unit is measured with an internal contents gauge. Check this gauge indicator and ensure that you have sufficient oxygen for your trip.
