Question:
2. The physiological zones
Answer:
10,000 ft - physiological zone 10,000-50,000 - physiologically deficient zone 50,000 ft - space
equivalent zone
Question:
3. Composition of the Atmosphere
Answer:
78% nitrogen, 21% oxygen, 1% other
Question:
4. Boyle's law
Answer:
At a constance temperature, the volume of gas is inversely proportional to the pressure to which it is
subjected
Question:
5. Dalton's law
Answer:
The total pressure of a mixture of gases is the sum of the individual pressures (Ptotal=P1+P2+P3...)
Question:
6. Charles' Law
Answer:
- if pressure remains contact, the volume of gas will vary with temperature
- if volume remains contract, the pressure of gas will vary with temperature
,Question:
7. Henry's law
Answer:
the amount of gas held in solution is proportional to the pressure of the gas above the solution
Question:
8. The law of Gaseous Diffusion
Answer:
a gas will move from an area of higher pressure to an area of lower pressure
Question:
9. upper respiratory tract
Answer:
Question:
10. Lower respiratory tract
Answer:
Question:
11. Circulation
Answer:
- 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
Question:
12. Blood & Pressure - 6 litres of blood in the body
Answer:
- 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
, Question:
13. Arteries and Veins
Answer:
- arteries take blood away from the heart
= high blood pressure
- veins take blood to the heart
= low blood pressure
Question:
14. Baroreflex
Answer:
- stretch receptors
- adjusts blood pressure
- takes 6-12 seconds
Question:
15. Gas expansion
Answer:
18 = 2 x 34 = 4 x 53 = 10 x
Question:
16. Body cavities and gas
Answer:
- teeth
- lungs
- gastrointestinal tract
- middle ear
- sinuses
- post-operative sites
Question:
17. Valsalva maneuver
Answer:
forced expiration against a closed nose/mouth
