Blood profile
Snakes
Glottis opens in the floor of the mouth
cavity, posterior to the tongue.
Direct intubation is easy (isoflurane - 5 %).
„Mask“ is not feasible method!
In young and small snakes - light is visible through the skin control.
Intubation
introduction - tiletamin-zolazepam
direct - isoflurane
The right „lung“ generally courses from near the hearth
to just cranial to the right kidney.
The anterior part of the lung is vascularized (gas excahnge)
- the posterior portion is nonrespiratory part - air sac.
