FLIGHT PHYSIOLOGY STUDY QUESTIONS
WITH ALL CORRECT ANSWERS
As pressure of a gas over a liquid decreases, amount of gas dissolved in liquid will also
decrease - Answer-Henry's Law
The rate at which gas moves through a small hole, avoiding interaction with other
particles, is related inversely to square root of the mass
of 1 mole of its molecules. - Answer-Graham's Law
• Inadequate ventilation or reduction in PO2
• Characterized by lack of oxygen entering blood
• In air environment, result of reduced atmospheric pressure causing reduced alveolar
PaO2 - Answer-hypoxic hypoxia
Cell's inability to use oxygen adequately - Answer-Histotoxic hypoxia
Failure to transport oxygenated blood - Answer-Stagnant Hypoxia
Reduction in ability of blood to carry oxygen to
tissues, despite oxygen's abundance - Answer-Hypemic Hypoxia
- Minor physiological effects - Experienced between sea level and 10,000´ - Answer-
Indifferent Stage
Body provides short-term compensation against hypoxia effects
- Experienced between 10,000´ and 15,000 - Answer-Compensatory Stage
-Characterized by subjective, objective hypoxia symptoms
- Cognition impairment most critical - Experienced between 15,000´ and 20,000´ -
Personality manifestations - Muscular coordination decreases - Answer-Disturbance
Stage
- Occurs within 3-5 minutes
- Mental confusion, quickly followed by incapacitation, unconsciousness, death
- Experienced between 20,000´ and above - Hyperventilation - Answer-Critical Stage
Dehydration
