Polysomnogram

A polysomnogram is a procedure that records a variety of body functions during sleep, including eye movement, muscle activity, and electrical activity of the brain. This test is done as part of a series of sleep tests to diagnose sleep disorders, such as sleep apnea, and problems staying awake or sleeping.

This test is often done in a sleep lab. It is monitored by a trained sleep lab technician. Small pads or patches called electrodes are attached to the person's head and body to record brain activity, eye movements, muscle movements, heart rhythm and rate, limb movements, and snoring. There is no pain or physical discomfort associated with these tests. Recording equipment and video monitors record the person's movements and activities during sleep. The technician is in a separate room monitoring the test.

The test results will available in a few weeks.
