AVIT 309 FINAL Questions and Answers
(100% Correct Answers) Already Graded A+
acclimatization [ Ans: ] •Full physiological adaption to
altitude takes 18.4 days per mile (5280 ft) of altitude
-can't acclimatize to above 10,000 feet
barometric pressure [ Ans: ] -decreases 1/3 from sea level
to 10,000
-decreases 1/2 10,000 to 18,000
zone of normal adaptation [ Ans: ] - Located up to 10,000
feet MSL
- We adapt to increase oxygen delivery
- Decreased oxygen delivery at these altitudes does not
impair performance
zone of physiologic deficiency [ Ans: ] - 10,000 feet to
50,000 feet
- Unable to adapt and function normally
- Conventional life support equipment is needed to
support normal functioning
•Equipment needs to vary with altitude, conditions
, •Need increasing concentrations of oxygen and pressure
space equivalent zone [ Ans: ] •Specialized life support
equipment is needed
-Full Body pressure suit
-Sealed cabin
-Emergency pressurization system
controls of respiration [ Ans: ] •Primary: Brain monitors
carbon dioxide
- Natural CO2 accumulation triggers breathing
•Secondary: Aortic Bodies monitor oxygen saturation in
blood & CSF
- Respiratory rate increases during hypoxia
•Voluntary control of breathing
-Only for so long...
hypoxia [ Ans: ] •Oxygen deficiency in blood, body tissue
and cells sufficient to cause impairment of function.
-cognition is first thing to go
