Hypoxia results when the body _______. It generally is associated with flights at high altitude. However, other factors such as ________ abuse, heavy ________, and various ________ can interfere with bloods ability to ________ and _________ oxygen, thereby reducing the body’s tolerance to hypoxia. The four major types of hypoxia are:
7.
8.
9.
10.
- Lacks Oxygen
- Alcohol
- Smoking
- Medications
- Carry
- Absorb
- Hypoxic
- Hypemic
- Histotoxic
- Stagnant
The 4 stages of hypoxic hypoxia and associated altitudes are:
- Indifferent: 0-10,000 feet
- Compensatory: 10,000 - 15,000
- Disturbance: 15,000 - 20,000
- Critical: 20,000+
A smoker at sea level is actually at a physiological altitude of _________ feet compared to a non-smoker.
5,000
List the three prevention methods for hypoxic hypoxia:
- Time at altitude
- Using supplemental oxygen
- Pressurized cabin
To help prevent or relieve middle ear discomfort associated with changes in altitude, crew members can equalize pressure during descent by ________, ________, or _________________. If these methods do not work, personnel can perform the _________ maneuver. To do this, _______ the mouth, _______ the nose, tilt the head upwards, and ______ sharply.
- Swallowing
- Yawning
- Tensing throat muscles
- Valsalva
- Close
- Pinch
- Blow
If middle ear discomfort is not relieved by the action in the previous answer, you should _______ to a level at which pressure can be _______. A slow ________ is then recommended.
- Ascend
- Equalized
- Descent
