Overnight Sleep Studies

A visit to a sleep disorders facility for a sleep study is likely to be an experience for you. A sleep study, or polysomnogram. is a recording that includes measurements used to identify different sleep stages and classify various sleep problems.

During sleep testing, the activities that go on in your body during sleep (brain waves, muscle movements, eye movements, breathing, snoring, heart rate and leg movements) are monitored by small electrodes applied to the head and skin with adhesive. Flexible elastic belts around your chest and abdomen measure your breathing.

In order to fully understand your sleep and any problems with it, we need to look at various brain activities and body systems and their relationships throughout the night. After the study a sleep specialist will review and interpret to help you and your health care professional with specific treatment.
