Aviation Medicine UPDATED ACTUAL Questions and CORRECT
Answers
1. Atmospheric divi- troposphere, stratosphere, mesosphere, thermosphere, exosphere
sions
2. The physiological 10,000 ft - physiological zone
zones 10,000-50,000 - physiologically deficient zone
50,000 ft - space equivalent zone
3. Composition of 78% nitrogen, 21% oxygen, 1% other
the Atmosphere
4. Boyle's law At a constance temperature, the volume of gas is inversely proportional to the
pressure to which it is subjected
5. Dalton's law The total pressure of a mixture of gases is the sum of the individual pressures
(Ptotal=P1+P2+P3...)
6. Charles' Law - if pressure remains contact, the volume of gas will vary with temperature
- if volume remains contract, the pressure of gas will vary with temperature
7. Henry's law the amount of gas held in solution is proportional to the pressure of the gas above
the solution
8. The law of a gas will move from an area of higher pressure to an area of lower pressure
Gaseous Diffu-
sion
9. upper respiratory
tract
10. Lower respirato-
ry tract
, 11. Circulation - 2 atria, 2 ventricles
- valves ensure one-way blood flood
- right ventricle = blood into lungs
- left ventricle = rest of the body
- contraction of ventricles = pulse
12. Blood & Pressure - 6 litres of blood in the body
- 50 % plasma, 50% blood cells
- red cells carry oxygen
- normal blood pressure = 230/80
- stroke volume = amount of blood ejected each beat
- cardiac output = 3-5 litres/min
13. Arteries and - arteries take blood away from the heart
Veins = high blood pressure
- veins take blood to the heart
= low blood pressure
14. Baroreflex - stretch receptors
- adjusts blood pressure
- takes 6-12 seconds
15. Gas expansion 18 = 2 x
34 = 4 x
53 = 10 x
16. Body cavities and - teeth
gas - lungs
- gastrointestinal tract
