About This Clinic
Greater Regional Sleep Medicine Center
Greater Regional Medical Center has offered highly specialized sleep lab services since 2001. Our team is specially trained in the diagnosis and treatment of sleep disorders, including:
- Sleep-disordered breathing or snoring which may be caused by certain obstructive or central nervous system disorders
- Problems staying awake as a result of conditions such as narcolepsy
- Daytime sleepiness or insomnia resulting from conditions such as restless legs syndrome or sleep apnea
Lack of adequate sleep is associated with a variety of chronic diseases, such as cardiovascular disease, obesity, and diabetes and also is often a factor in motor vehicle collisions which result in injury and disability. According to the CDC, more than 25% of the U.S. population report they occasionally do not get enough sleep and nearly 10% experience chronic insomnia. Adequate sleep is important to one’s good health.
GREATER REGIONAL SLEEP LAB
Our sleep lab provides a comfortable testing environment for optimal results. Your comfort during the procedure is important to us and we have supplied our sleep rooms with sleep number beds as well as individual temperature controlled rooms.
Dr. Annie Nawab is our medical director and is board certified in internal medicine, critical care, pulmonology and sleep medicine. Pulmonology and Sleep Medicine Clinics are offered in Greater Regional Medical Clinics.
A patient may be tested using one or more of the following sleep study methods. Sleep studies are conducted to learn what is causing your sleep problems and record what happens to your body while you are sleeping. Sleep problems include: sleep apnea, which is when an adult regularly stops breathing during sleep for 10 seconds or longer; excessive snoring; restless legs; difficulty staying awake during the day, nighttime behaviors such as nightmares or sleep walking; and difficulty sleeping during the day due to work shifts at night or rotating shifts. You may be requested to maintain a sleep diary to record your sleep patterns prior to your sleep test. During your preparations, following your normal sleep patterns is important for best test results.
SLEEP CENTER TESTS
- Polysomnographic Study (PSG): this study records a variety of body functions during sleep, including electrical activities of the brain, heart rate, muscle activity, eye movement, breathing, air flow through the nose and mouth, and blood oxygen levels.
- Continuous Positive Airway Pressure Study (CPAP): This study is similar to the routine PSG, followed by initiation and evaluation of your CPAP needs. CPAP is used to treat sleep apnea.
- Multiple sleep latency test (MSLT). This study measures how long it takes you to fall asleep and determines whether or not you enter REM sleep.
- Maintenance of wakefulness test (MWT). This study measures whether you can stay awake during a time when you are normally awake.
All sleep studies are scored by credentialed technicians and results are interpreted by Dr. Nawab. If needed, referrals to specialty physicians such as neurologists, otolaryngologists (ear, nose and throat physicians) will be made to assist your physician in developing your individual treatment plan.
