Respiratory medicine Flashcards
1
Q
Effects of the environment on respiratory
A
Decreased partial pressure of oxygen oxygen systems cold dry air or oxygen use of pressure breathing and PPBG smoker and fumes hypobaria eg gas trapping or expansion acceleration and V/Q mismatching Anti G straining Shiftwork and time zones exertion
2
Q
Effects of respiratory disorders on aviation
A
Distraction from symptoms incapacitation, insidious or acute multisystem disorders Cognitive disturbance impair alertness/fatigue Treatment side effects and logistics
3
Q
Asthma, environment on conditions
A
Cold dry/oxygen Smoke and fumes Reduced oxygen partial pressure pressure breathing gas trapping, barotrauma exertion
4
