HYPERVENTILATION
Hyperventilation, or overbreathing, is a disturbance of respi-
ration that may occur in individuals as a result of emotional
tension or anxiety. Under conditions of emotional stress,
fright, or pain, breathing rate may increase, causing
increased lung ventilation, although the carbon dioxide out-
put of the body cells does not increase. As a result, carbon
dioxide is nwashed out" of the blood. The most common
symptoms of hyperventilation are: dizziness, nausea, sleepi-
ness, and finally, unconsciousness. If the symptoms persist,
discontinue use of oxygen and consciously slow your
breathing rate until symptoms clear, and then resume nor-
mal breathing rate. Normal breathing can be aided by talk-
ing aloud.
ALCOHOL
Common sense and scientific evidence dictate that you
must not fly as a crew member while under the influence of
alcohol. Alcohol, even in small amounts, produces (among
other things):
• A dulling of critical judgement.
• A decreased sense of responsibility.
• Diminished skill reactions and coordination.
• Decreased speed and strength of muscular reflexes
(even after one ounce of alcohol).
• Decreases in efficiency of eye movements during read-
ing (after one ounce of alcohol).
• Increased frequency of errors (after one ounce of alco-
hol).
• Constriction of visual fields.
• Decreased ability to see under dim illuminations.
• Loss of efficiency of sense of touch.
• Decrease of memory and reasoning ability.
