What is the test of multiple latency of sleep?
Multiple sleep latency is a study used to help doctors precisely diagnose various sleep disorders, including narcolepsy and excessive daily drowsiness. The all -day test takes place in an accredited sleep center and supervises certified technicians, nurses and doctors. The patient gets a comfortable, quiet private room and is left to take four or five naps with about two hours during the day. The monitoring device is used to detect changes in brain and eye activity and determine whether there is a failure.
different sleep centers and laboratories can have their own versions of the test of multiple latency of sleep, but most tests are performed very similarly. Before a multiple latency test can occur, the patient must usually stay in the center of sleep at night so that doctors can monitor the night patterns in the procedure called polysomnography. The test results overnight are used as the default for daily tests to monitor changes.
during the latency test with multiple sleepAnd the polysomnographic studies are attached to the chest, forehead, chin, under the eyes. Data on the activity of brain wool, heart rate, eye movement and contraction of the face muscles are collected by an electronic monitoring machine. The test procedure is completely painless and sleep technicians are trying to carry the sensors and wires as comfortable as possible.
After the night of the polysomnographic test, the patient is encouraged to stay up for about two o'clock in the morning. He is then asked to try to fall asleep again. Sleep technician records time that takes the patient to actually enter the patient, and then monitors the activity of the brain and eye to determine when deep sleep or fast eye movement (REM) is achieved. The patient is awakened for about 15 or 20 minutes to take a nap and instruct to stay up for Another for two hours. Most sleep centers perform four or five Naps on the patient, so a person can expect to be in Sthoroughly at least seven hours.
Once testing is completed, the patient can go home and technicians, psychologists and doctors can start analyzing the results. Information about how long it took the patient to fall asleep during each nap can help doctors assess the possibility of narcolepsy or other chronic drowsiness. In general, the latency test with multiple sleep, which shows that the person falls asleep within five minutes and, quickly entering the REM phase, testifies to a basic failure. Once the finding is carefully reviewed, the physician may explain the results to the patient and discuss the treatment options.
