Sleep Studies

Sleep studies are the only way to find out if a person has a sleep disorder. They are a painless test that monitors body functions such as airflow, brain waves, heart rate, leg movements, pulse oximetry and breathing during sleep.

At the University of Michigan Sleep Disorders Center, we conduct the tests in a comfortable hotel-like setting. A well-trained sleep specialist technician will talk with you about the study, answer any questions, place sleep-testing electrodes on your body, and be available all night should you need anything.

We can also provide in-home testing to qualified individuals.

After the Study

One of our sleep medicine physicians will score and interpret your study within 7-10 days.

If your physician is part of our Sleep Disorders Clinic, we will notify you by letter to explain that we placed an order for CPAP or BiPAP equipment with a Durable Medical Equipment (DME) company near your home. The DME company will contact you within 1 to 2 weeks after we send the order to schedule an appointment for you to pick up your equipment.

If your physician is not with the U-M Sleep Disorders Clinic, you should contact your physician to obtain your results and order your equipment.

The DME company will train you in how to use and take care of the CPAP equipment.


The American Academy of Sleep Medicine (AASM) accredits the University of Michigan Sleep Disorders Center to provide both laboratory and in-home sleep testing.
