The Sleep Study

A sleep study, known as a polysomnogram, is required to establish the presence of most sleep disorders including sleep apnea, periodic leg movements, narcolepsy, restless leg syndrome and more.

During a full sleep study, the patient’s brain wave activity, eye activity, heart rate, airflow from the mouth and nose, chest and abdomen movement, blood oxygen levels, body position, and muscle movements are all monitored. This is accomplished in a pain-free manner, with the use of patches and belts.

Depending on your insurance coverage, Stewart Memorial also offers AT-HOME sleep studies, in which patients can sleep at home. Our sleep techs provide a tutorial about how to wear and use the monitoring device.
