During a Sleep Test, a recording is made of many different body readings as you sleep throughout the night. This recording is called a polysomnogram. Physicians use the information polysomnograms provide to diagnose sleep disorders. 

Your polysomnogram may include information about your brain waves, muscle movements, eye movements, breathing through mouth and nose, snoring, leg movements, heart rate, and blood oxygen level. To record the information for your polysomnogram, small metal sensors called electrodes are applied to your skin with a mild adhesive.

During a Home Sleep Test, the electrodes on your skin transfer your body readings to a small device called a sleep recorder while you sleep. After awakening, you return the sleep recorder to the Sleep Disorders Center. The information it contains is then transferred to a computer, which creates your polysomnogram.

If your Sleep Test takes place in our Sleep Lab, the electrodes on your skin transmit your body readings to a computer, which in turn creates your polysomnogram. A sleep technician working with you monitors your sleep from a nearby room, leaving you undisturbed.

Whether your Sleep Test takes place at home or here in our Sleep Lab, your polysomnogram will be analyzed by our physicians and sleep specialists. They in turn develop a diagnosis, along with recommendations for treatment that they submit to your physician.
