Sleep Studies

The Winneshiek Medical Center Sleep Lab uses the talents of technologists and physicians from Mayo Clinic who are specially trained in sleep medicine to diagnose sleep disorders. You can be evaluated in the Sleep Lab through a referral from your doctor. WMC accepts referrals from all area clinics and providers.

Home Sleep Studies

If your doctor determines you meet criteria, you may be able to take a sleep study at home.

Winneshiek Medical Center’s home sleep study equipment allows patients to perform a sleep study at home rather than spending the night at the medical center.  This option is more convenient for patients and reflects your true sleep patterns because you are tested in a familiar environment – your home.  The equipment is easy to use and convenient for patients any day of the week.

Most insurances cover home sleep studies, and the WMC Respiratory Therapy team will work with your insurance company for pre-authorization of the service.  As soon as we get clearance from insurance, we can schedule your study – most of the time within the week. Members of the Respiratory Therapy team teach you how to set up the simple equipment, and when you are at home and ready to turn in for the night, just follow the three simple steps for the study.  The next day, return the equipment to WMC.  A Mayo Clinic sleep specialist reads the test and sends the results to your primary care doctor.

Talk to your doctor about sleep studies, and ask if the home testing option is right for you.  WMC accepts referrals from all area clinics and providers, or call Winneshiek Medical Center Decorah Clinic for an appointment: 563-382-2911.

In-house Sleep Studies

Some sleep studies take place at Winneshiek Medical Center.


When you arrive for your scheduled sleep study, please enter through the Emergency Room Entrance. Staff will escort you to the Sleep Lab. Once in the Sleep Lab, you will be asked to provide insurance information and your completed Sleep Questionnaire. Your doctor will give this to you before your sleep study.  You will then be asked to change into your sleeping clothes before you are taken to the preparation area.

Sleep Rooms

You will have your own private room where a Mayo Clinic sleep technologist will monitor you by computer and video from a separate control room. A private bathroom and shower are easily accessible for your use during testing. Following preparation for the sleep study, you will be taken to your room to sleep.


Sensors will be carefully attached to the outside of your body with special paste or tape so you will be able to move and turn as usual while you sleep.  Though the sensors do not hurt, your skin may be sensitive when they are removed in the morning.

Small electrodes will be attached to your scalp and face, and belts applied to your chest and legs. These electrodes will monitor your brain waves (EEG), heart rate (EKG), eye movement and muscle activity. This information helps identify various abnormalities that may be affecting your sleep. Small sensors will also be taped near your nose and mouth and two belts will be placed around your chest and abdomen to monitor your breathing. Your oxygen level will be monitored with a small finger sensor.

Some patients worry they will be unable to sleep well with all of these sensors in place. Most patients are able to sleep enough for the sleep technologist to obtain the information they need to diagnose a sleep disorder. If you are concerned about sleeping well in the sleep lab, you may ask your doctor for a sleep aide prescription prior coming in for your sleep study.

If you are being evaluated for sleep apnea, the sleep technologist will also size you for a CPAP mask.

In the morning, the sleep technologist will wake you, remove all sensors and ask about your night of sleep. Testing is generally done by 7 am.

Follow up

After your sleep study, it is very important that you discuss your test results with your doctor. Your sleep study report will be available to your doctor within one week of your test. The follow up may take place over the phone or at the office, depending on your doctor’s preferences. Individual treatment options will be based on the results from your sleep study.
