Polysomnography (sleep study) is the recording of many biological functions while asleep. The sleep study is performed over a 10-12 hour period at night while the patient sleeps.

Application of the electrodes takes approximately 1 to 1 1/2 hours while the remaining time is spent sleeping. The patient is observed via a closed circuit camera and a technician records the patients' movements during the study.

The results of the sleep study are scored by a Registered Polysmonography Technologist and interpreted by a Physician Board Certified in Sleep Disorders. The scored report and interpretation is accompanied by a letter of recommendation to the patient's physician.
