Sleep tests are called polysomnography to record brain waves during sleep, to detect oxygen levels, and to avoid diagnosing sleep disorders. The tests also help diagnose problems with breathing and heartbeat during sleep. These tests are done in a hospital or specialized sleep center. In these recordings made during sleep, the quality of the stages of sleep and the symptoms seen in these stages are observed. Studies are usually done on night sleep.
What is a Night Sleep Test? How is it done?
The night sleep test is the method used to calculate the number and duration of dream periods, deep sleep periods and awakening reactions after the sleep stages are determined for approximately 7 hours of shooting by attaching electrodes to the head and chin of the patient hospitalized in the sleep laboratory.
Electrodes are attached to certain parts of the body and the patient is monitored and recorded. These are:
- recording the respiratory effort of the patient with a small device attached to the nose, belts attached to the thorax and abdomen,
- the blood oxygen level in sleep with a finger-mounted sensor,
- Sleep heart rhythm with EKG electrode
- is the recording of leg movements with electrodes attached to the legs.
With the position sensor, it is determined in which position the patient has an increase in respiratory arrest. br> The next day, the whole night shot was watched again by the responsible doctor and the patient;
- sleeping stages and waking reactions,
- abnormal respiratory events,
- sleeping leg movements,
- body position and many more parameters are marked one by one.
What is the Daytime Sleep Test/Multiple Sleep Latency Test (MULT)?
Some of the patients with excessive daytime sleepiness can't sleep in the night test.
In a group of these patients, narcolepsy causing excessive sleepiness may not be detected. A daytime sleep test is performed to investigate the disease or idiopathic hypersomnia.
In this test, called Multiple Sleep Latency Test (MULT), the patient is hospitalized for a total of 5 sleeps every 2 hours, and the diagnosis is reached by monitoring the time to fall asleep, and if he has fallen asleep, whether he has entered the REM phase during this time. .
To Who, When and How Should Sleep Tests Be Performed?
