Private Pilot - Medical Facts Flashcards
What is Hypoxia?
Hypoxia is a state of oxygen deficiency in the body sufficient to impair functions of the brain and other organs.
What 4 types of Hypoxia are there?
Hypoxic, Stagnant, Hypemic, and Toxic.
What are the symptoms of Hypoxia?
Impaired judgment, vision, memory, alertness, and coordination. Headache, drowsiness, dizziness, euphoria, cyanosis, and numbness.
What actions should you take if Hypoxia symptoms are present while in flight?
Reduce altitude, and use supplemental oxygen.
What is Sinus Block?
Air pressure in the sinuses equalize through small openings in the nasal passages during altitude changes.
Either an upper respiratory infection, such as a cold or sinusitis, or a nasal allergic condition can produce enough congestion around an opening to slow equalization, and as the difference in pressure between the sinus and cabin mounts, eventually, plug the opening.
How can you prevent Sinus Block?
Don’t fly with an upper respiratory infection or nasal allergies.
What is Hyperventilation?
Hyperventilation is the excessive rate and depth of restoration leading to abnormal loss of carbon dioxide from the blood.
What are the symptoms of Hyperventilation?
Visual impairment, unconsciousness, lightheaded/dizziness, muscle spasms, tingling, and hot and cold sensations.
How should you treat Hyperventilation?
Restore proper carbon dioxide level to the body, by breathing at a normal rate; you can do this my breathing into a paper bag or talking aloud.
What is spatial disorientation?
is the lack of orientation with regard to the position, attitude, or movement of the airplane in space.
What systems do the body use to recognize movement through space and orientation?
Vestibular, Somatosensory, and Visual.
What is the illusion, False Horizon consist of?
When a sloping cloud formation, ground lights, or stars create a false line that appears to be the horizon, and a pilot attempts to align with the false horizon.
What is Autokinesis?
when flying in the dark, a stationary light may appear to move if it is stared at for a prolonged period of time, which may cause the pilot to align or fly with the perceived moving light.
At night it is possible to see a reversible perspective illusion, what is that?
when an aircraft seems to be moving away from a second aircraft when it is actually approaching it.
Hypoxic Hypoxia
Insufficient oxygen available to the body as a whole.
