Sleep Studies

A sleep study is the most accurate test for diagnosing sleep apnea. It captures what happens with your breathing while you sleep. A sleep study is often done in a sleep center or sleep lab, which may be part of a hospital. You may stay overnight in the sleep center.


A polysomnogram (poly-SOM-no-gram), or PSG, is the most common study for diagnosing sleep apnea. This test records:

  • Brain activity
  • Eye movement and other muscle activity
  • Breathing and heart rate
  • How much air moves in and out of your lungs while you're sleeping
  • The amount of oxygen in your blood

A PSG is painless. You will go to sleep as usual, except you will have sensors on your scalp, face, chest, limbs, and finger. The staff at the sleep center will use the sensors to check on you throughout the night.
A sleep specialist reviews the results of your PSG to see whether you have a sleep disorder and how severe it is. He or she will use the results to plan your treatment.

What can I expect during a Sleep Study?

Our sleep studies typically begin at 8:00 p.m. For night shift workers, we will try to schedule your study during your normal sleeping hours. We will explain the procedure and prepare you for the study.
You will spend the night in one of our private rooms as we observe your sleep. If your physician prescribes a sleep aid bring it with you as we are unable to dispense medication. Your study should be done by 8:00 a.m. the next morning (unless you stay for a day study also).
We are equipped to set you up with your therapeutic needs (CPAP, Bi-PAP, etc). These options will be discussed with you in the morning if the study indicates you qualify for treatment.
After your sleep study is completed our board certified sleep specialist will meet with you in the morning after your sleep study to discuss the results of your sleep study and possible treatment options. 
All of our facilities offer private comfortable rooms with cable TV. We feature high quality Select Comfort queen-sized beds, as well as a handicapped accessible bathroom and shower. If you need to stay through the next day for additional testing, lunch is also provided.
Because of the possibility of a day study, we ask that you make arrangements to be available for continuous testing the following day if necessary.
Bring comfortable, loose fitting apparel, such as pajamas, to sleep in. We recommend that you bring all your toiletries such as toothbrush, toothpaste, etc. You are also welcome to bring your favorite pillow, blanket, or anything else that helps you sleep.

Daytime Multiple Sleep Latency Test (MSLT)

For someone who reports being sleepy during the day, it is sometimes helpful to measure how sleepy they are. Also, after treatment of sleep problems, we sometimes want to measure improvement in daytime sleepiness. Sleepiness can be measured with a Multiple Sleep Latency Test (MSLT). Basically, the MSLT measures how fast someone falls asleep during the day. It must be done after an overnight sleep study (polysomnography), which documents adequate opportunity for sleep the night before. The test is composed of 4 to 5 "naps" that lasts 20 minutes and are spaced 2 hours apart. The person is instructed to, "Try and fall asleep." The average time to fall asleep is calculated for all 4 or 5 tests. Normal time would be greater than 10 minutes to fall asleep. Excessive sleepiness is less than 5 minutes to fall asleep.

Maintenance of Wakefulness Test (MWT)

The Maintenance of Wakefulness Test (MWT) also measures daytime sleepiness. The person in this test is instructed to, " try and stay awake." This is repeated for four 40 minute sessions, 2 hours apart. Not falling asleep in all 4 tests is the strongest objective measure of no daytime sleepiness.

Some agencies use these tests to ensure that their employees are not excessively sleepy while at work. Specifically, airline pilots and truck drivers who have sleepiness, need to be tested. This is done for public safety and work productivity. Unfortunately, there is no test that will guarantee that someone will not fall asleep at his or her job or while driving.

CPAP Services and Sleep Disorders Treatment

Sleep Center of Central Minnesota offers therapeutic services to our patients who may benefit from positive pressure therapy. The most common and most effective treatment for obstructive sleep apnea (OSA) is the use of Continuous Positive Airway Pressure (CPAP) or Bi-Level Positive Airway Pressure (Bi-Level). CPAP and Bi-Level therapy are non-invasive and considered the first line of treatment for OSA. The general theory behind this type of treatment is that it applies a positive pressure to the airway to keep it from closing during sleep.
Upon your decision to use Sleep Center of Central Minnesota for your therapy needs, our staff will take you through an extensive education session on the use of CPAP or Bi-Level. The advantage to using Sleep Center of Central Minnesota for your OSA therapy needs is that you will not only have received the most thorough education possible, but you will also be followed very closely by members of our staff. Compliance is a common issue with CPAP therapy; our experience has shown that proper mask fit and patient education combined with experienced CPAP specialists results in outstanding results and patient compliance.

Ongoing Support

Our compliance program includes follow-up calls made to CPAP/Bi-Level patients at 3 days, 30 days, 60 days and every 6 months thereafter after initiation of equipment use. We also offer free mask exchange during the first 30 days to make certain your mask is the best available for you.
We have full-time CPAP Specialists available to help with any ongoing equipment and supply needs. An auto-mail program is also available to interested patients for hassle-free supply replacement.
CPAP and Bi-Level therapy equipment and supplies are covered by most insurances.

Breathing Devices (CPAP/Bi-Level)

Continuous positive airway pressure (CPAP) is the Gold Standard and most effective treatment for sleep apnea in adults. A CPAP machine uses a mask that fits over your nose or nose and mouth. The machine gently blows air into your throat.

The air presses on the wall of your airway.
The air pressure is adjusted so that it's just enough to stop the airway from becoming narrowed or blocked during sleep.

Normal Breathing 
Airway is open 
Air flows freely to lungs 
Airway collapses
Blocked air flow  

Airway splinted open
Air flows freely to lungs

Treating sleep apnea may eliminate snoring.  Snoring cessation, however, does not mean that you no longer have sleep apnea or can stop using CPAP. Sleep apnea will return if CPAP is discontinued or used incorrectly.
Typically a CPAP specialist will meet with you the morning after your sleep study to set you up with the CPAP equipment.  The technician will adjust the CPAP based on your doctor's orders.  After the initial setup, you may need to have the CPAP adjusted on occasion for the best results.

People who have sleep apnea symptoms generally feel better once they start treatment with CPAP.
