Sleep Lab

Sleep can often be a barometer of your overall health. In many cases, people in good health tend to sleep well, whereas repeated sleeping problems may indicate an underlying medical or mental health problem, be it minor or serious. Sleeping well is essential to your physical health and emotional well-being. Unfortunately, even minimal sleep loss can take a toll on your mood, energy, efficiency, and ability to handle stress. Ignoring sleep problems and disorders can lead to poor health, accidents, impaired job performance, and relationship stress. If you want to feel your best, stay healthy, and perform up to your potential, sleep is a necessity, not a luxury.

It is estimated that over 50 million American adults experience sleep disorders and intermittent sleep disruptions and 18 million Americans suffer from obstructive sleep apnea.  Mercy Medical Center's Sleep Lab, located in the Department of Neurophysiology, has been diagnosing sleep disorders for over 23 years.  Our staff of registered sleep technologists, along with board certified sleep specialist physicians, is dedicated to providing the highest quality of care available.  In our four-bed sleep lab, we have performed thousands of overnight sleep studies to help the people of Siouxland get a good night's sleep.

Is It A Sleep Disorder?

  • Do you snore?
  • Are you tired day after day?
  • Have you been told that you stop breathing in your sleep?

If you answered yes to any of these questions, you could be suffering from sleep apnea.  Sleep apnea is a condition in which muscles in the back of the throat fail to keep the airway open, resulting in a decrease of oxygen to the brain.  This leads to frequent awakening during the night.  This continuous disruption of sleep can lead to high blood pressure, mood and memory problems, decreased concentration and, in severe cases, stroke or heart attack. 

Other sleep disorders evaluated in the sleep lab include Periodic Limb Movements in Sleep (PLMS) as well as narcolepsy, nocturnal seizures and REM behavior disorder.

Your first step in determining if you have a sleep issue should begin by visiting with your physician, who will determine if you need to be referred to Mercy's Sleep Lab for an overnight sleep study, also known as a polysomnogram.  If a sleep study is recommended, you should plan on spending the night in the sleep lab (or daytime if you work overnight).  Several non-invasive and painless monitors are attached, which evaluate various measurements including brain wave activity, breathing, oxygen level, leg movements and heart rhythms.  A sleep technologist will be watching your activity from another room during the sleep study and recording data.  This data is tabulated and presented to the sleep specialist for their interpretation and a report is sent to your physician within a week following the study.
