![]() ![]() Polysomnography: In polysomnography, a sleep technician monitors a patient who stays overnight at a specialized clinic.Different types of sleep studies are available depending on one’s symptoms and the sleep disorders that may be present. Sleep studies collect data about what is happening in a person’s body during sleep. This may take up to two weeks, when you’ll schedule a follow up to discuss the results. The data from your sleep study will usually be taken by a technologist, and later evaluated by your doctor. A sleep study will also measure things such as eye movements, oxygen levels in your blood (through a sensor-there are no needles involved), heart and breathing rates, snoring, and body movements. While you sleep, an EEG monitors your sleep stages and the cycles of REM and nonREM or NREM sleep you go through during the night, to identify possible disruptions in the pattern of your sleep. For this test, you will go to a sleep lab that is set up for overnight stays-usually in a hospital or sleep center. What Is a Sleep Study?Ī sleep study is a non-invasive, overnight exam that allows doctors to monitor you while you sleep to see what’s happening in your brain and body. Often these disorders cannot be identified with a normal office visit-your doctor needs to gather more conclusive evidence while you’re asleep. Sleep studies help doctors diagnose sleep disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and nighttime behaviors like sleepwalking and REM sleep behavior disorder. If your doctor suggests you undergo a sleep study, or polysomnography, you may be wondering what is involved in this test and what to expect.
