Chapter 8.5 - Exam Review Flashcards
Prolonged exposure over many years to the typical noise level in the cockpit of a light Aircraft (30 dB/90 dB), can cause permanent hearing loss?
90 dB.
‘Greying out’ is most likely to occur at (3g to 4g/2.5g)?
3g to 4g.
Total loss of vision under a sustained load of 4.5g to 5.5g is called (grey out/black out)?
Black out.
Increasing degrees of hypoxia followed by loss of consciousness are most likely (below/above) 5.5g?
Above.
With increased (positive/negative) g, the blood pools in the lower abdomen and legs. This pooling drains the blood from the brain and starves it of (carbon dioxide/oxygen)?
- Positive.
- Oxygen.
Under increased (positive/negative) g, the blood vessels within the transparent membrane covering the whites of the eyes become enlarged and are visible as a red mist known as ‘red-out’?
Negative.
Name three sources of the highly toxic gas, carbon monoxide?
- Exhaust Fumes.
- Cigarette Smoke.
- Fire.
What are the early symptoms of carbon monoxide poisoning (3)?
- Feeling Unease.
- Inability to think clearly.
- Dizziness.
The body is affected by carbon monoxide poisoning in the same way as it is by hypoxia, with one major difference. Briefly explain this difference?
Hypoxia is removed almost immediately with oxygen supply. Even with the use of oxygen, carbon monoxide will remain in the body for a considerable amount of time.
Like hypoxia, effects of carbon monoxide poisoning (decrease/increase) with Altitude?
Increase.
How should carbon monoxide poisoning be treated?
Remove sufferer from the source of gas and supply oxygen.
True or False. Breathing in fumes from fuels and lubricants usually causes headache, nausea and drowsiness?
True.
What is the basic cause of motion sickness?
Continued stimulation of the balance organ in the inner ear.
True or False. Noise interferes with communication in the cockpit and can cause headache and fatigue on a long flight, thus impairing performance?
True.
