Flashcards in Aeromedical Deck (11):
1

Types of Hypoxia:

-Hypoxic:

-Not enough oxygen pressure (altitude - lack of O2 in the body)

2

Types of Hypoxia:

-Hypemic

-Reduction in the O2 carrying capacity of the blood (carbon monoxide, smoking, etc)

3

Types of Hypoxia:

-Histotoxic

-Interference with the use of O2 by body tissues (alcohol, drugs, poison (cyanide)

4

Types of Hypoxia:

-Stagnant

-decrease in circulation, pooling of blood (medical conditions, extreme G forces)

5

Stages of Hypoxia:

-Indifferent:

-sea level - 10,000 ft PA, 98-90% O2

6

Stages of Hypoxia:

-Compensatory:

-10,000-15,000 ft PA, 89-80% O2

7

Stages of Hypoxia:

-Disturbance:

-15,000-20,000 ft PA 79-70% O2

8

Stages of Hypoxia:

-Critical:

- >20,000 ft PA, 69% and below O2

9

Prevention of Hypoxia:

-Limit time at altitude
-Use supplemental O2
-Pressurize the cabin

10

Treatment of Hypoxia:

-Administer 100% O2
-Descent to altitude below 10,000 ft PA

11

Hypoxia:

-Definition

-State of oxygen deficiency in the body for any reason.
