IA Med/ACE Flight Physiology Exam
Practice Questions and Answers

What are relative contraindications for taking patients in flight? - Answer✔✔-Anemia (low Hgb)

and 24+ week gestation pregnancy. The rise in altitude can trigger baroreceptors and induce

early labor


What is AGL in flight physiology? - Answer✔✔-Above ground level. (Aircraft to ground level)


What is MSL in flight physiology? - Answer✔✔-Mean Sea Level (how far from the plane to the

mean sea level)


What is ASL in flight physiology? - Answer✔✔-Above sea level. So instead of the mean, this is

the actual distance from the aircraft to the sea if you're flying over it


What decreases with altitude? What stays the same? - Answer✔✔-The actual oxygen

concentration of 21% is the same, but the partial pressure of oxygen decreases. So diffusion is

not as readily available since the high pressure moves to low pressure areas for diffusion across

alveoli. Well less pressure means the process occurs slower. So your body has to work harder

due to the lower pressure to maintain the same perfusion. PR and RR increase


What is barometric pressure at sea level? - Answer✔✔-760 Torr. (One atmosphere)

If I dive three atmosphere, how many feet is that? If I dive 99 feet, how many atmosphere is

that? - Answer✔✔-66. One at the surface, plus two more




4 atmosphere. one at the surface, plus three atmosphere


How many feet is 1/2 atmosphere? - Answer✔✔-18k ft MSL (mean sea level)


What zone is the space zone? - Answer✔✔-Anything above 50,000 ft


What would exit your body at 63k feet? - Answer✔✔-All fluids because there's no pressure to

hold it in. If you weren't in a pressurized cabin


Name the altitude zones. - Answer✔✔-Space equivalent - 50,000ft + MSL


Deficient zone - 10,000-50,000 feet


Efficient zone - Sea level - 10,000 feet


Can you survive in the deficient zone? - Answer✔✔-Yes, but your body will compensate through

PR and RR because it has to work harder to maintain oxygenation and perfusion by increasing

cardiac output. Due to low pressure


What zone do humans function well in? - Answer✔✔-The efficient zone


The FAA requires oxygen to the pilot and crew at how many feet if you are flying for 30+

minutes in an unpressurized cabin? - Answer✔✔-10,000 feet to prevent hypoxia
