AVIT 309 Exam I UPDATED ACTUAL
Exam Questions and CORRECT Answers
How long does it take to fully physiologically acclimatize to a given altitude and the maximum
altitude of acclimatization? - CORRECT ANSWER - 18.4 days per mile
10,000'
What is the barometric pressure density characteristics of the atmosphere? - CORRECT
ANSWER - decreases as we go up in altitudue
halfway point is at 18,000'
What are the physiological divisions of the atmosphere? - CORRECT ANSWER - zone of
normal adaption (0-10K)
zone of physiologic deficiency (10K-50K)
space equivalent zone (50K+)
Boyle's Gas Law - CORRECT ANSWER - a volume of gas is inversely proportional to its
subjected pressure, the temperature remaining constant (trapped gas)
Charles' Gas Law - CORRECT ANSWER - the pressure of a gas is directly proportional to
its temperature (fluctuation of oxygen bottle pressure)
Henry's Gas Law - CORRECT ANSWER - the amount of gas dissolved in a solution is
proportional to the partial pressure of that gas over the solution (decompression sickness)
Graham's Gas Law - CORRECT ANSWER - gasses will diffuse from an area of high
concentration to an area of low concentration (respiration & weather)
Dalton's Gas Law - CORRECT ANSWER - the total pressure of a mixture of gas is equal
to the sum of the partial pressure of each gas in the mixture (hypoxia)
, What are the human breathing mechanics? - CORRECT ANSWER - Ventilation
Respiration
Transportation
Utilization
inhale is active and exhale is passive
How does pressure breathing change the normal breathing rates? - CORRECT ANSWER -
pressure breathing reverses mechanics
exhale is active and inhale is passive
What are the controls of respiration rates in human beings - CORRECT ANSWER - #1
CO2
#2 O2
What is the purpose of pressure breathing? - CORRECT ANSWER - maintains normal
oxygen transfer in the lungs at higher altitudes
Four factors that determine partial pressure of oxygen in the lungs? - CORRECT
ANSWER - oxygen
pressure
water vapor
carbon dioxide
What are the four types of hypoxia? - CORRECT ANSWER - hypoxic
histotoxic
hypemic
stagnant
