SAFETY INFORMATION
Symptoms are slow but progressive, insidious in onset, and are most marked
at altitudes starting above ten thousand feet. Night vision, however, can be
impaired starting at altitudes lower than 10.000 feet. Heavy smokers may ex-
perience early symptoms of hypoxia at altitudes lower than non-smokers.
Use oxygen on flights above 10,000 feet and at any time when symptoms ap-
pear.
HYPERVENTILATION
Hyperventilation or over-breathing, is a disturbance of respiration that may
occur in individuals as a result of emotional tension or anxiety. Under condi-
tions of emotional stress, fright, or pain, breathing rate may increase, causing
increased lung ventilation, although the carbon dioxide output of the body
cells does not increase. As a result, carbon dioxide is "washed out" of the
blood. The most common symptoms of hyperventilation are: dizziness; hot
and cold sensations; tingling of the hands, legs and feet; tetany; nausea;
sleepiness; and finally unconsciousness.
Should symptoms occur that cannot definitely be identified as either hypoxia
or hyperventilation try three or four deep breaths of oxygen. The sytnptoms
should improve markedly if the condition was hypoxia (recovery from hypoxia
is rapid). If the symptoms persist, discontinue use of oxygen; consciously
slow your breathing rate until sytnptoms clear; then resume normal breathing
rate. Normal breathing can be aided by
talking aloud.
Common sense and scientific evidence dictate that you not fly as a crew
member while under the influence of alcohol. Even small amounts of alcohol
in the human system can adversely affect judgment and decision making
abilities.
FAR 91.11 states "(a) No person may act as a crew member-(I)
within 8 hours
afler the consumption of any alcoholic beverage."
Tests indicate that as a general rule.
2
ounces(.06 liters) of alcohol at 15,000
feet produce the same adverse effects as
6
ounces(.l8 liters) at sea level. In
other words, the higher you get, "the higher you get".
Self-medication or taking medicine in any form when you are flying can be ex-
tremely hazardous. Even simple home or over-the-counter remedies drugs
such as aspirin, antihistamines, cold tablets, cough mixtures, laxatives,
trati-
quilizers, and appetite suppressors, may seriously impair the judgment and
coordination needed while flying. The safest rule is to TAKE NO MEDICINE
before or while flying, except on the advice of your Aviation Medical Examiner.
