Your Sleep Study

The Sleep Studies

The Sleep Studies

To complete your sleep disorder diagnosis, you will undergo one of two types of sleep studies:

  • Night-Time Polysomnogram (NPSG), or
  • Multiple Sleep Latency Test (MSLT).

The names of these studies may sound intimidating, but actually, both are simple and painless observations of your sleep patterns.

Night-Time Polysomnogram (NPSG)
The NPSG helps determine your body's activity while you sleep during the night. Your brainwave pattern, muscle tension levels, eye movements, body movements, heart rate and the amount of air you breathe will be recorded and evaluated by our staff. Typically, this study begins at 9:00 p.m. and ends at approximately 7:30 a.m.

Multiple Sleep Latency Test (MSLT)
The MSLT measures how sleepy you are during the day. During five 20-minute daytime nap periods, your brainwave pattern, muscle tension levels, eye movements and heart rate are recorded and evaluated. Typically the first nap begins at 9:00 a.m. and the last nap ends at 5:30 p.m. You will nap at approximately 2-hour intervals.

For both of these studies, recording devices (sensors) will be placed on your head, chest and legs. Using computerized equipment, a highly trained sleep technologist will then observe your sleep patterns from a separate control room as you sleep uninterrupted.

NOTE: If you normally work the night shift and sleep days, we can schedule your study during your usual sleep time.

If you have any questions, feel free to call the Sleep Center at (608) 229-7979.

How To Prepare

How to Prepare for Your Sleep Study

Before you come to the Center, we recommend you prepare yourself by following the suggestions given below. These guidelines will help you sleep during the study. If you have any questions, feel free to call the Sleep Center at (608) 229-7979.

  • Avoid naps.
  • Get plenty of exercise during the day, but not within two to three hours of your appointment.
  • Relax as much as possible before your visit.
  • Avoid caffeinated beverages such as coffee, tea and cola, eight hours before your appointment.
  • Limit your fluid intake to 16 ounces (2 cups) within three hours of your appointment.
  • Please shower/bathe and shampoo on the day of your appointment. Hair should be free of hairspray, mousse, gels, etc.

What You'll Need

What You'll Need to Bring 

When you come to the Sleep Center, feel free to bring with you anything that you may want or need during your stay. Items may include nightclothes, toiletry articles, medications, a bedtime snack, reading materials or even a teddy bear! If you like to sleep in your underwear, bring a T-shirt to wear as well.

Clean bed linens and pillows are provided, but we encourage you to bring your own pillow; it will help you sleep.

Please bring necessary insurance information, such as ID card. We strongly encourage you to contact your insurance company as soon as possible to make sure you are covered or pre-approval is met. If you have questions regarding insurance coverage, please contact your insurance company.

Also plan to bring a form of ID. Please be prepared to provide a photo ID when you check-in. We do not need a picture to provide care and will not withhold treatment due to lack of identification. Acceptable forms of ID include Driver's License, State Issued ID, Student ID, Military ID or Proof of Residence (Utility Bill, Bank Statement, Pay Check).
