In our sleep study lab provides a board-certified sleep medicine physician with the most complete evaluation of your sleep. You will be required to stay overnight at our sleep center, hospital or in a home. In` our in-lab sleep study, also known as a polysomnogram, records your brain waves, heartbeats and breathing as you sleep. It also charts your eye movements, limb movements and oxygen in your blood. This data will help your doctor make a diagnosis and develop a treatment plan. For some patients suspected of obstructive sleep apnea, the sleep physician may recommend a home sleep apnea test instead of an in-lab study. A home sleep apnea test uses different equipment that you can set up yourself. An in-lab sleep study is the way to ensure that you have the proper diagnosis for a sleep disorder. Speak with your health care provider if you think you might need a sleep study.
