Aeomedical Factors and ADM

Question 1

Hypoxic hypoxia is ______

Answer 1

a result of insufficient oxygen available to the body as a whole

Question 2

Hypemic hypoxia occurs when

Answer 2

he blood is not able to take up and transport a sufficient amount of oxygen to the cells in the body. The oxygen deficiency is in the blood, not the result of too little inhaled oxygen.

EXAMPLE:  Carbon monoxide poisoning

Question 3

Stagnant hypoxia results when

Answer 3

oxygen-rich blood in the lungs is not moving.

EXAMPLE:  Shock, reduced circulation due to extreme cold, or pulling excessive Gs in flight

Question 4

Histotoxic hypoxia is the

Answer 4

inability of cells to effectively use oxygen.

EXAMPLE:  Impairment due to alcohol and drugs

Question 5

Symptoms of hypoxia include

Answer 5

an initial feeling of euphoria but lead to more serious concerns such as headache, decreased reaction time, visual impairment, and eventual unconsciousness

Question 6

The correct response to counteract feelings of hypoxia is

Answer 6

to lower altitude or use supplemental oxygen.

Question 7

Hyperventilation occurs when

Answer 7

an excessive amount of air is breathed out of the lungs, e.g., when one becomes excited or undergoes stress, tension, fear, or anxiety.

Question 8

Physiologically, hyperventilation results in

Answer 8

an excessive amount of carbon dioxide passed out of the body and too much oxygen retained

Question 9

Symptoms of hyperventilation include

Answer 9

dizziness, hot and cold sensations, nausea, etc.

Question 10

Overcome hyperventilation by

Answer 10

slowing the breathing rate, breathing into a bag, or talking aloud.

What are first symptoms of carbon monoxide poisoning?

Answer 14

Blurred (hazy) thinking and vision, uneasiness, dizziness, and tightness across the forehead are early symptoms of carbon monoxide poisoning.

Question 15

What are later symptoms of carbon monoxide poisoning?

Answer 15

They are followed by a headache and, with large accumulations of carbon monoxide, a loss of muscle power.

Question 16

What effect does altitude have on carbon monoxide poisoning, and why?

Answer 16

increases in altitude increase susceptibility to carbon monoxide poisoning because of decreased oxygen availabilit

Question 17

What are the 5 hazardous attitudes of ADM, and what are teh antidotes?

Answer 17

Antiauthority: Don’t tell me!; Follow the rules. They are usually right.

Impulsivity: Do something quickly!; Not so fast. Think first.
