7. Total atmospheric Pres- Decreases
sure on the body (in-
creases/ decreases) with
altitude?
8. What are the physical troposphere, stratosphere, mesosphere, thermosphere (TSMT)
divisions of the atmos-
phere?
9. Boyle's Law The volume of a gas varies inversely with its pressure at constant
temperature. (balloon)
"Boyle's Balloon"
10. Dalton's Law (Dalton's The total pressure of a gas mixture is the sum of all individual gas
addition) pressures.
11. Henry's Law (Henry's The quantity of gas dissolved in a given volume of liquid is proportional
Heineken) to the partial pressure of the gas in contact with the liquid. (soda bottle)
12.
, Graham's Law (graham's Describes the rate of effusion (gas movement through a pinhole). Gas
gradient) will move from areas of high concentration to areas of low concentra-
tion.
13. Primary function of Cir- Blood transport (oxygen/nutrient transport), waste removal, body
culatory System temp regulation,
14. Hemoglobin What is the Protein within the RBC that is composed of four protein
chains and carries O2 molecules for transport to tissues by binding it
to iron?
15. Respiratory functions intake oxygen and remove carbon dioxide, maintenance of body heat,
maintenance of PH.
16. Inhalation/ exhalation inhalation is active, exhalation is passive
active or passive?
17. Gaseous Diffusion gas moves from areas of high pressure to low pressure.
18. Alveoli carbon dioxide and oxygen move in and out of the
due to pressure differentials between gases.
19. as altitude increases, The pressure differential between oxygen molecules across the alveo-
blood oxygen saturation lar- capillary membrane is critical. How does this affect a crewmember
decreases, leading to hy- with an increase in altitude?
poxia.
20. Hypoxia State of oxygen deficiency in the blood cells and tissues, suflcient to
cause impairment of function.
21. Hypoxic Hypoxia Type of hypoxia that results in Reduction in oxygen in the lungs due to
high altitude. Not enough air.
22. Hypemic Hypoxia
, Type of hypoxia that results in Reduction in oxygen in the blood due to
carbon monoxide, blood loss, or anemia
23. histotoxic hypoxia Tissue unable to use O2 because it has been poisoned. (cyanide,
alcohol, narcotics)
24. Stagnant Hypoxia Lack of circulation of blood (heart failure, pressure points, high Gs)
25. Symptoms of Hypoxia Fatigue, nausea, numbness, dizziness, air hunger, belligerence, tin-
gling, numbness, blurred vision, apprehension, hot & cold flashes,
denial, euphoria
26. Signs of hypoxia Loss of muscle coordination, hyperventilation, unconsciousness,
slouching,
27. Hypoxia prevention/ limit time at altitude, minimize self imposed stressors, pressurized
treatment cabin, 100% 02, descend to a safe altitude.
28. Oxygen is required for: What are the oxygen requirements at various altitudes?
10,000 ft more than 1
hour, 12,000 ft more
than 30 min, 14,000 ft
no matter what, 18,000
ft need to prebreathe O2
for 30 min prior.
29. Stages of Hypoxia (ICDC) Indifferent: sea level to 10,000ft
Compensatory: 10,000ft to 15,000ft
Disturbance: 15,000ft to 20,000ft
Critical: 20,000+
