Someone keeping you up at night?
You may be one of 70 million Americans
Millions of people had trouble sleeping last night. Untreated, sleep disorders put people at higher risk of an irregular heart rate, heart disease, stroke, hypertension, diabetes, depression, memory loss, and also have a low sex drive. Fortunately, most sleep disorders are treatable once diagnosed. Knoxville Hospital & Clinics’ Sleep Disorders Program is here to provide the tools to end your sleepless nights.
Do you have a sleep disorder?
A sleep study is needed to properly diagnose and treat your sleep disorder. People who suffer from sleep disorders may have symptoms of:
- Loud, chronic snoring
- Anxiety and mood changes
- Gasping for breath at night
- Morning headaches
- Increased sleepiness during the day, while driving, and on the job
- Restlessness while sleeping at night
- Difficulty in falling asleep
- Reduction in concentration, memory, and attention
The Sleep Disorders Program sees both adult and pediatric patients with a variety of sleep disorders.
There are many classifications of sleep disorders. Here are some of the most common ones.
- Obstructive sleep apnea: A life-threatening disorder that causes you to stop breathing repeatedly during your sleep.
- Periodic limb movement syndrome: When people’s legs or arms jerk during sleep.
- Restless leg syndrome: A persistent, sometimes overwhelming need to move one’s legs while resting.
- Insomnia: Difficulty in falling and staying asleep.
- Narcolepsy: Characterized by the brain’s inability to control its sleep/wakefulness cycle.
- Parasomnia: Nightmares, sleepwalking, sleep talking, and bedwetting.
Sleep studies provide the answer
Our sleep specialists administer several types of diagnostic sleep studies at KHC’s Sleep Disorders Program, including home sleep tests, Continuous Positive Airway Pressure therapy, overnight polysomnography, multiple sleep latency test (also called a nap study), and maintenance of wakefulness test (a daytime polysomnographic procedure).
Sleep Lab patients enjoy the comfort of a private room, private bathroom for personal care, as well as a Sleep Number® bed.
During Sleep Lab studies, electrodes transmit and record your sleep patterns and specific information about your physical activities, such as breathing, brain waves, heart activity, and eye and muscle movements. The recording techniques are noninvasive (external) and all electrodes are applied on the skin surface. The entire process is painless. The recordings become data which is analyzed by Medical Director Dr. Melisa Coaker in addition to her staff to determine the nature of your sleep disorder, and then report the findings and treatment recommendations to your primary care provider.

A Polysomnography or PSG is a noninvasive, diagnostic test that uses the same sensors as the HST, but also includes EEG, EKG, EMG, and other biologic measurements in a laboratory setting with sleep technician. Polysomnographies are performed at the Knoxville Hospital & Clinics’ Sleep Lab.
Preparing for the Sleep Study
A sleep study involves an overnight stay at the sleep lab. Our patient rooms are set up to make you as comfortable as possible so you can have a full night’s sleep.
On This Day You Should
- Try to follow your regular routine as much as possible’
- Avoid napping
- Eliminate use of caffeine after lunch
- Avoid using hair sprays or gels that can interfere with the sleep recording
- If you are on a regular medication, speak with your Family Medicine provider to determine whether any medication should be temporarily discontinued.
When it is time to report for your sleep study, bring any items that you need for your nightly routine. Prepare for the sleep study as if you are staying at a hotel for a night. You may want to bring:
- Comfortable pajamas or clothes to sleep in
- A toothbrush, toothpaste and hair brush
- Makeup remover
- Reading material
- Clean clothes for the morning
When you arrive, a sleep technologist will ask about your sleep habits. There may be a pre-sleep questionnaire for you to fill out.
You will have some time to make yourself at home. There will not be any other patients in your room.
When you are ready to go to bed, the sleep technologist will attach sensors to your body. The sensors, which are glued or taped to you, monitor your body while you sleep. These sensors are painless. Make sure to tell the technologist if you are allergic or sensitive to any adhesives.
The wires are long enough to let you move around and turn over in bed. At the start of the test, you will be asked to move your eyes, clench your teeth and move your legs. This will make sure that the sensors are working.
You are free to read or watch TV until your normal bedtime. When it is time for you to try to go to sleep, the lights will go off and a low-light video camera will allow the technologist to see you from a nearby room. If a sensor comes loose or you need to go to the bathroom during the night, the technologist will have to help you with the wires.
Many patients do not sleep as well as they would at home. This may be because of the sensors or the unfamiliar environment. This typically does not affect the results. Nearly everyone falls asleep during an in-lab study. In most cases, you do not need a full eight hours of sleep for the doctor to make a diagnosis. Occasionally, you may be prescribed medication to help you sleep during the in-lab sleep study.
In the morning the technologist will test and then remove the sensors. You may be asked to fill out a morning questionnaire that asks about the quality of your sleep and your experience in the sleep center. The in-lab study is complete once you are awake and the sensors have been removed.
Once the study is complete, the data is forwarded to and interpreted by the clinic’s medical director, Melisa A. Coaker, M.A., M.D. Once the data is interpreted, a diagnostic interpretation report is sent back to the ordering Family Medicine provider.
Hours of Operation
For our patients’ convenience, sleep studies are usually offered Friday and Saturday, but other arrangements can be made if those days don’t work. Patients usually check in at approximately 8 p.m. and leave the following morning by 5 or 6 a.m.
