temperature lapse rate.
Efficient zone - Sea level to 10,000 feet (760 mm Hg to 523 mm Hg)
Deficient zone - 10,000 to 50,000 feet (523 mm Hg to 87mm Hg)

1% Other - 0.03% CO2 -RIGHT ANSWERWhat is the composition of
the atmosphere?
Pre-breathe oxygen for 30 minutes and then on supplemental oxygen
at all times -RIGHT ANSWERIf flying at 18,000 feet what are the
oxygen requirements?
10,000 ft. - 1 hour of flight allowed before oxygen is required
12,000 ft. - 30 Minutes of flight allowed before oxygen is required
14,000 ft. - oxygen is required at all times -RIGHT ANSWERWhat are
the oxygen requirements for flight?

,Barometric Pressure -RIGHT ANSWERThe measurement of pressure
exerted on the earth's surface from the gases and water in the
atmosphere
29.92 in. Hg or 760 mm Hg. -RIGHT ANSWERWhat is the Barometric
Pressure at sea level?
Dalton's Law -RIGHT ANSWERThe pressure exerted by a mixture of
gases is equal to the sum of the partial pressures of each gas in the
mixture
Oxygen and nutrient transport to the cells
Transport of metabolic waste products to organ removal sites
Assists in temperature regulation -RIGHT ANSWERFunctions of the
Circulatory System
Arteries (Oxygenated)
Veins (Deoxygenated)
Capillaries -RIGHT ANSWERComponents of the circulatory system
Plasma
White blood cells
Platelets
Red blood cells -RIGHT ANSWERComponents of Blood
Intake of Oxygen[O2]
Removal of Carbon Dioxide [CO2]
, Maintenance of body heat balance
Maintenance of body acid base balance [pH] -RIGHT ANSWERWhat
are the Functions of the Respiratory System?
Inhalation is active
Exhalation is passive -RIGHT ANSWERWhat are the Phases of
Respiration?
Alveoli -RIGHT ANSWERWhere does the oxygen exchange occur in
the lungs?
Gas molecules of higher pressure move in the direction of gas
molecules of a lower pressure -RIGHT ANSWERLaw of Gaseous
Diffusion
State of oxygen deficiency in the blood cells and tissues sufficient to
cause impairment of function -RIGHT ANSWERDefine Hypoxia.
Hypoxic - reduced O2 in the lungs, occurs at high altitude.
Hypemic - Blood cells cannot accept O2 (CO poisoning or blood loss).
Stagnant - Inadequate circulation (pressure point of G forces).
Histotoxic - inability of the tissue cell to accept or use oxygen
(Cyanide, alcohol, or Narcotics) -RIGHT ANSWERWhat are the four
types of hypoxia?
Air hunger
Apprehension
Fatigue
