Why do I need a sleep study?

In order for us to fully evaluate your sleep and any potential sleep disorders, an all-night sleep test, also called a polysomnogram (PSG), may be done. The test records brain waves, breathing, heart rate, oxygen, muscle tone and other functions. After the study, a sleep specialist will review and interpret the record to help you and your health care provider understand your specific sleep disorder. Treatment recommendations will be made when your medical history and the results of your physical examination and sleep test have been reviewed.
