Sleep Disorders Center

Everyone sleeps, but not everyone sleeps well.

Every night, more than 70 million Americans who suffer from a sleep disorder struggle to get a good night's rest, according to the American Academy of Sleep Medicine (AASM). The St. John Sleep Disorders Center provides the latest resources in the diagnosis and treatment of sleep problems. Our multidisciplinary team of medical professionals helps patients manage their sleep disorders and restore their quality of life.

Accredited by AASM, St. John ranks among the top sleep disorders centers in the U.S. To receive accreditation, a sleep center must meet or exceed all standards for professional health care as designated by AASM. The accreditation process involves detailed inspection of a center's facility and staff, including an evaluation of testing procedures, patient contacts and physician training. Additionally, the facility's goals must be clearly stated and include plans for positively affecting the quality of medical care in the community it serves.

The Sleep Disorders Center is a full-service center for the diagnosis and treatment of sleep disorders. Conveniently located on the St. John Medical Center campus, the Sleep Disorders Center includes 10 hotel-like private bedrooms with private bathroom and shower facilities. The adjoining high-tech monitoring area is equipped with polysomnographs and other sensitive instrumentation used to detect sleep issues.

What to Expect in a Sleep Study

At the Sleep Disorders Center, we evaluate patients' respiration and other physiologic measurements while they sleep. Small electrodes are attached to the skin to measure snoring, eye and leg movements, muscle and brain wave activity, oxygen saturation, respiratory effort and heart rate. Breathing is monitored by measuring airflow at the nose and mouth. These measures do not interfere with normal breathing, and no significant discomfort or risk is involved.

To confirm the diagnosis of narcolepsy or document the presence of pathological daytime sleepiness, a series of four or five 20-minute daytime naps, spaced at two-hour intervals, are performed following an overnight sleep study. Following diagnosis, treatment will be administered based upon the severity of the sleep disorder and corresponding health issues.

The Sleep Disorders Center also offers an AASM-approved Home Sleep Testing (HST) Program, an easy and affordable way to have a sleep study performed. With the HST Program, the patient visits St. John to be informed on how to properly use the unit and apply the sensors, then takes it home for the night and returns it the next morning. The patient will meet with a physician to go over the results, and the physician will make a diagnosis and recommendations for therapy. Most health insurance plans will cover home sleep testing at little to no cost to the patient.

Common Sleep Disorders

  • Narcolepsy – a disorder that causes periods of extreme daytime sleepiness and can also cause muscle weakness, hallucinations and sleep paralysis.
  • Obstructive sleep apnea – a disorder in which the flow of air pauses or decreases during breathing while asleep because the airway has become narrowed, blocked or floppy.
  • Central sleep apnea – a disorder in which breathing repeatedly stops and starts during sleep because the brain doesn’t send proper signals to the muscles that control breathing.
  • Insomnia – a disorder that causes trouble falling asleep or staying asleep through the night.
  • Restless leg syndrome – a disorder in which there is an urge or need to move the legs to stop unpleasant sensations.
