What is a sleep failure test?

millions of people around the world suffer from sleep disorders, including sleep apnea, insomnia, narcolepsy and restless foot syndrome. To diagnose these common diseases, doctors may require the patient to undergo a sleep disorder test, which is usually performed overnight at the clinic of sleep disorders. During the sleep failure test, the measurement is carried out to categorize the sleep phases and detect any sleep irregularities. Information from the test failure test is interpreted by a trained physician who then determines whether or not there is a sleep disorder.

Sleep failure test may include polysomnograms that are often referred to as a study of rapid eye movement and tests of more latency of sleep. In these tests, the patient must be monitored by sleep technician. The patient is generally obliged to arrive in a study about two hours before his typical time of the bed and is asked to delay drinking drinks with alcohol or caffeine for some time before studying to obtain accurate reading.

beforeThe patient goes to sleep, the electrodes are temporarily attached to his chin and head and over the lids. Electrodes will pick up the electrical signals produced by the brain and also help record muscle activity. The information is then transmitted via wires and recorded during the sleep failure test on strips.

During the study overnight, the tests also monitor the condition of sleep. These states include the movement of the fast eye and the impatient movement of the eyes, which is measured by electromyogram and electro -oial machines. A person with healthy sleep patterns usually alternates between two sleeping patterns every 90 minutes and has about five cycles of fast eye and non -stiff eye movement at night. Other things that are monitored during a sleep study include Hdlou it takes the patient to fall asleep and the amount of time required to move the eyes rapidly.

heart rate and person's breathing are also carefully monitored during a sleep failure testby the power of electrocardiogram. Sleep technician will observe a patient who records any changes in his breathing or heart rate. Usually, a person with a sleep disorder, especially sleep apnea, will have cases where he stops breathing for a moment during sleep. The number and length of these episodes is recorded.

The

latency test of sleep is usually performed in laboratories of sleep after a sleep disorder test in people suspected of narcolepsy. This test is carried out in the morning and determines the amount of time the needy to nod during the day. During the test, the person at regular intervals is taken several naps. A person with narcolepsy usually falls asleep in less than five minutes.
