Sleep Study

A sleep study is a non-invasive exam that allows doctors to monitor you while you sleep to see what is happening in your brain, body and sleep patterns. For this test, you will go to a sleep lab that is set up for overnight stays or it can also be done at home. While you sleep, an EEG monitors your sleep stages and cycles to identify possible disruptions in your sleep pattern. A sleep study will also measure things such as eye movement, oxygen levels in your blood (through a sensor, no needles are involved), heart and breathing rates, snoring and body movements.
