Sleep Disorders Center

Getting a good nights' sleep is an essential part of health and well-being. Millions of people do not get the sleep they need and suffer from some type of treatable sleep disorder. The most common disorders are:

  • Obstructive Sleep Apnea (OSA): a common condition that causes a person to stop breathing, on occasion, during sleep.
  • Narcolepsy: a condition that causes a person to fall asleep suddenly at inappropriate times, such as while talking or diving.
  • Insomnia; a condition during which a person has difficulty falling or staying asleep.
  • Restless Leg Syndrome: sleep is disruptive by spontaneous twitches or jerks in the arms or legs.
  • Snoring: a condition when breathing is rough or noisy during sleep.

The Sleep Disorders Center assists in diagnosing and treating patients with any sleep disorders. It's not uncommon many people are found to have a sleep disorder and report no sleeping problems prior to testing. Although some of the symptoms are considered harmless, a part of life or growing, in truth, these symptoms are pointing to a larger underlying issue.

Our Sleep Disorders Center and Home Sleep testing is fully accredited through the Accreditation Commission for Health Care (ACHC). We are staffed with specialty trained physicians and technologists, who strive to provide the highest quality of care to all of our patients, and to increase the awareness and promote treatment of Sleep Disorders in our community.

Why do I need a sleep study?

A sleep study is commonly performed to investigate the following symptoms:

  • Unrefreshed sleep
  • Daytime sleepiness
  • Breath-holding episodes during sleep
  • Snoring
  • Leg twitching/restless legs at night
  • Abnormal behaviors at night

If these symptoms and disorders are left untreated, it can lead to an increased risk of heart attacks, hypertension, stroke, depression and increased likelihood of diabetes.

What is involved in a sleep study?

A sleep study is performed to evaluate sleep disorders by examining and monitoring a person's behavior while sleeping. The sleep study is a painless all-night procedure during which electrodes are placed on the patient's scalp, chin, chest and legs to record all body movements during sleep. In addition, an elastic belt is secured around the abdomen to record breathing and the wires are placed near the nose and mouth to record air flow during breathing. Finally, a small device is placed on the finger to record oxygen saturation. Sleep studies are typically done at the hospital, but can be done at home if certain criteria are met. A consultation will determine the appropriate setting for your sleep study.

Types of Screenings

Polysomnogram (PSG)

PSG consists of collecting information about movements, breathing, heart rate, snoring and other events during a sleep study. This is typically done overnight, but may be done during daytime hours if patient is a shift-worker or sleeps during the day.

Multiple Sleep Latency (MSLT)

MSLT assesses your level of daytime sleepiness. MSLTs are often recommended for potential Narcolepsy and are usually done during the day (following an all-night sleep study). Patients are screened during five 20-minute nap sessions, approximately 2 hours apart. Between naps you will be asked to stay awake.

Maintenance of Wakefulness Tests (MWT)

MWT is designed to assess your level of daytime alertness. An MWT will show whether you are able to stay awake for a certain amount of time. This type of sleep study will be conducted in a dim, quiet room and you will be asked to sit peacefully for 40 minutes for each trial.

Electroencephalograph (EEG)

A test utilizing a collection of electrodes to record the patient's electrical brain activity.

Home Sleep Testing (EEG)

This test has sensors that will track your oxygen level, heart rate and breathing patterns. You will be contacted with an appointment time and date to come to the UnityPoint Health – Keokuk Sleep Disorders Center. A technician will instruct you on how to apply the equipment to wear that night in the comfort of your home. The equipment will be returned the next day.
