Polysomnography

This is a test of sleep cycles and stages through the use of continuous recordings of brain waves (EEG), electrical activity of muscles, eye movement (electrooculogram), respiratory rate, blood pressure, blood oxygen saturation, and heart rhythm and direct observation of the person during sleep. Polysomnography is conducted in a sleep laboratory. You will lie on a bed in the special room. The test may be carried out during the night so that normal sleep patterns can be reproduced. Electrodes are placed on the scalp, the outer edge of the eyelids, and to the skin on the chin in preparation for the test. Characteristic patterns from the electrodes are recorded during wakefulness with the eyes closed and during sleep. The time taken to fall asleep is measured as well as the time to enter REM sleep. At our laboratory the movements of a person during sleep are recorded by video camera.
