Sleep Apnea Tests
There are a couple of tests that can be done to help your doctor find out if you have sleep apnea.
Polysomnography Test - Sleep StudyA polysomnography test, commonly called a sleep study is used to determine the severity and type of sleep apnea. During a sleep study, a technician will monitor airflow, oxygen levels, muscle movements, eye movements, and brainwave activity during sleep. There is no pain involved with this test. Complete test results should reveal the number of times breathing stopped during sleep and if the apnea is obstructive or central in origin.
Multiple Sleep Latency TestDuring a multiple sleep latency test, a person is given several opportunities to fall asleep during the daytime (or any time when he or she would not normally be sleeping). A person with a sleep disorder may fall asleep in less than five minutes while a person without any sleep disorders will fall asleep in about 10 - 20 minutes. This test is used to determine the degree of excessive daytime sleepiness a person is experiencing. While excessive daytime sleepiness is associated with a number of diseases, it is one of the main symptoms of sleep apnea.
