Aeromedical Factors Questions with
100% Correct Answers
What is Hypoxia? Correct Answer: The result of reduced oxygen or inadequate
oxygen transportation.
Types of Hypoxia Correct Answer: Hypoxic
Hypemic
Histotoxic
Stagnant
Hypoxic Hypoxia Correct Answer: The result of an insufficient supply of oxygen to
the body as a whole. For pilots, this is caused due to a low partial pressure at
higher altitudes (normally higher that 12,000ft MSL) resulting in decreased
molecules to pass through membranes in the respiratory system.
Dry Ice can cause this. Releases CO2
Hypemic Hypoxia Correct Answer: Results from the bloods inability to transport
oxygen through the body. Can be caused by Carbon monoxide poisoning
(200x more attracted to hemoglobin), reduced blood volume (blood donation)
, or anemia.
Histotoxic Hypoxia Correct Answer: A result of blood cells inability to effectively
use oxygen, even though there is enough oxygen being transported. Can be
caused by Alcohol and other drugs. Every ounce can be equated to
approximately 2000 ft in Physiological altitude.
,Stagnant Hypoxia Correct Answer: Caused by the lack of oxygen rich blood
flowing from the lungs to the tissue that needs it. This can result from excessive
acceleration of gravity (Pulling to many G's), shock, constricted arteries, or the
heart failing to pump.
Symptoms of Hypoxia Correct Answer: Euphoria and a carefree feeling.
Some of the typical symptoms are as follows
I. Cyanosis
II. Headache
III. Decreased reaction time
IV. Impaired judgement
V. Euphoria
VI. Visual impairment
VII. Drowsiness
VIII. Lightheadedness
IX. Dizziness
X. Tingling in fingers and toes
XI. Numbness
, What is useful consciousness? Correct Answer: The maximum time available to
make rational, lifesaving decisions and carry them out at a given altitude
without supplemental oxygen.
What can you do to correct Hypoxia? Correct Answer: Get to a lower altitude
I. Emergency decent
Use supplemental oxygen
What causes Hyperventilation? Correct Answer: Results from insufficient carbon
dioxide in the blood as a result for excessive rate and depth of breath
What are symptoms of hyperventilation? Correct Answer: I. Visual impairment
II. Unconsciousness
III. lightheaded or dizziness
IV. Tingling sensation
V. Hot and cold sensations
VI. Muscle spasms
What are solutions to hyperventilation? Correct Answer: The purpose of the
following fixes is to restore the proper carbon dioxide levels to the body.
I. Forcibly breath slower
