1. Hypoxia is _____.
A state of oxygen deficiency in the body
A state of oxygen excess in the body
The result of less oxygen in the air at higher altitudes
2. Hypoxia is more common at higher altitudes because as altitude increases, the percentage of oxygen in the atmosphere decreases.
3. You may experience hypoxia at any altitude, including sea level.
4. When flying at night, one of the first symptoms of hypoxia is the deterioration of vision.
5. High-altitude physiology training, such as an altitude chamber "flight", is no longer recommended because most pilots experience the same symptoms of hypoxia.
6. Which items can render the body more susceptible to hypoxia?
Alcohol (beer, wine, etc.)
Antihistamines (allergy medications: Benadryl, Actifed, etc.)
Sedatives (medications with calming effects: sleeping pills, Valium, etc.)
Analgesics (pain and fever reducers: aspirin, acetaminophen, ibuprofen, etc.)
All of the above
7. Histotoxic hypoxia happens when cells and tissues are unable to use the oxygen supplied to them. This typically occurs when_____.
A toxin, such as alcohol or narcotics, has been absorbed by the cells
The body's ability to carry oxygen molecules is limited due to breathing excess carbon monoxide
The blood flow through the body is restricted during positive-G maneuvers in aerobatic flight
8. Hypemic hypoxia occurs when the blood is not able to accept and transport a sufficient amount of oxygen to the body's cells. This is typically a result of _____.
A toxin, such as alcohol or narcotics, being absorbed by the cells
The body's ability to carry oxygen molecules being limited due to breathing excess carbon monoxide
The blood flow through the body being restricted during positive-G maneuvers in aerobatic flight
9. According to the regulations, at altitudes above 12,500 feet MSL up to and including 14,000 feet MSL, when must the flight crew be provided with, and use, supplemental oxygen?
After 30 minutes
After 45 minutes
10. According to the regulations, the flight crew must be provided with, and use, supplemental oxygen upon immediate exposure to altitudes above _____.
14,000 feet MSL
15,000 feet MSL
18,000 feet MSL
