Areomedical Factors

Question 0

Hypoxia

Answer 0

Hypoxia is a state of oxygen deficiency in the body sufficient to impair functions of the brain and other organs. Hypoxia from exposer to altitude is due only to the reduced barometric pressure encountered at altitude, for the concentration of oxygen in the atmosphere remains about 21% from the ground to outer space

Question 1

What are the 6 main Aeromedical factors(AIM 8-1-2

Answer 1

Hypoxia
Ear Block
Sinus block
Hyperventilation
Decompression sickness after scuba
Carbon monoxide poisoning

Question 2

4 types of hypoxia

Answer 2

Hypoxic
Hypemic
Histoxic
Stagnate

Question 3

Hypoxic

Answer 3

Is a result of insufficient oxygen available to the body as a whole. A blocked airway and drowning are examples on how the lugs can be deprived of oxygen. but the reduction in partial pressure of oxygen at high altitudes is for pilots. The precent of oxygen remains the same but there are fewer molecules available at the pressure required for them to pass between the membranes in the respiratory system

Question 4

Hypemic

Answer 4

Hypemic occurs when the blood is not able to take up and transport a sufficient amount of oxygen to the cells in the body. Hypemic means “not enough blood”. This type of hypoxia is a result of of oxygen deficiency in the blood, rather then a lack of of inhaled oxygen. Most commonform of hypemic is CO2 poisoning. The actual blood molecule that is transports oxygen, is chemically unable to bind oxygen molecules.

Question 5

Histoxic

Answer 5

The inability of the cells to effectively use oxygen is defined as histotoxic. Histo refers to tissues or cells,and “toxic” means poisonous. In this case there is enough oxygen transported to the cells that need it but, but they are unable to make use of it.

Question 6

Stagnant

Answer 6

Stagnant means” not flowing”, this results from when the oxygen-rich blood in the lungs is not moving, for one reason to another, to the tissue that needs it. It can also be caused by pulling “G’s” in thr aircraft.
