Aeromedical Factors Flashcards
What regulations apply to medical certification?
Part 67 Medical standards and certification
Why is hypoxia? What are the symptoms? Types?
State of oxygen deficiency
drowsiness, dizziness, euphoria, tingling in extremities
Hypoxia-altitude (partial pressure)
Hypemic-carbon monoxide
Stagnant-Excessive Gs, slow blood flow
Histoxic-alcohol, meds, toxins in your body tissue
What factors make a pilot more susceptible to hypoxia?
Carbon monoxide Anemia Medications Alcohol Extreme heat or cold Fever Anxiety
What is hyperventilation? Symptoms?
How to stop?
Abnormal increase in volume of air breathed in and out of lungs.
Lightheaded, drowsy, tingling in extremities, uncoordinated, disorientation
Consciously bring rate of breathing back under control, best if breathing into a paper bag
What is spatial disorientation? What causes it?
Lack or orientation in regard to position in space and in relation to other objects
Eyes, inner ear, even nerves/joints/muscles work together to provide orientation but forces of flight can provide misleading information to these organs causing disorientation
What should you do if pax or pilot suffers from motion sickness inflight?
Open air vent Loosen clothing Oxygen Eyes on point outside ac Avoid unnecessary head movement
What is carbon monoxide poisoning?
What should you do if you suspect it?
Colorless, odorless has contained in exhaust fumes. When breathed even in small quantities reduces the ability of your blood to carry oxygen. Consequently hypoxia sets in
Immediately shut off heater and open all air vents

24 hrs if diving required controlled ascent or you’ll be flying higher than 8,000ft
