During a sleep study the sleep cycles and stages of sleep are
monitored. Electrodes are placed to monitor continuous recordings
of brain waves, electrical activity of muscles, eye movement,
respiratory rate, blood pressure, blood oxygen saturation, and
heart rhythm. Direct observation of the person during sleep may
also be used. The test is performed for people who suffer from
insomnia, excessive daytime sleepiness, obstructive sleep apnea,
breathing difficulties during sleep, or behavior disturbances
during sleep.
