    The Sleep Disorders Center is in operation 24 hours a day, Monday through Saturday. Self-referrals are accepted, but most patients are referred by physicians, usually pulmonary or ear, nose and throat specialists.

    Patients undergo sleep testing in one of two specially designed bedrooms in the Center. The bedrooms are accessible to the physically challenged and are comfortably equipped with overhead television sets and reading lamps, to help simulate a homelike environment. Except for special circumstances, all testing is performed at night.

    Brian Margolis, MD, who is board-certified in sleep medicine, leads a team of physicians and technical staff in the diagnosis and treatment of various sleep disorders. All testing in the Sleep Disorders Center is interpreted by a Board Certified Sleep Specialist.

    Key Indicators of Sleep Apnea

    • Bed partner witnesses and reports the cessation of breathing
    • History of snoring • Excessive Daytime Sleepiness (EDS)
    • High blood pressure
    • 17-inch or greater neck circumference

    Individuals who snore loudly every night should be suspected of having sleep apnea, especially if they experience sleepiness during the day. Snoring, which is interrupted by pauses, then gasps, indicates that the sleeper's breathing stops and restarts. Sleep apnea leads not only to daytime sleepiness but also can trigger high blood pressure, heart disease, stroke and morning headaches. Daytime sleepiness can interfere with concentration at work or school, and can make driving dangerous.
