Sleep Studies

The Sanford Sleep Disorder Center has been performing sleep tests for more than 20 years to help diagnose sleeping disorders including sleep apnea, narcolepsy and insomnia.

What to Expect at Your Appointment

The sleep study takes approximately seven hours. For most people, sleep studies will not interfere with daytime activities such as work, school or family responsibilities.

The Sleep Disorder Center is designed exclusively for sleep studies. While patients sleep in quiet, comfortable rooms, technicians at an adjacent monitoring station observe and record, using sophisticated equipment, such things as sleep patterns, heart and respiratory activity and body movements.

Resembling a hotel room, Sanford Sleep Disorder Center rooms provide those undergoing a sleep study with comfortable accommodations. Each sleep room has a queen-sized bed, recliner, TV, toilet and a shower with shampoo, soap, towels and washcloths. There will be some wires attached with paste to your head, chin, chest and legs (this paste will wash off with soap and water). The test will finish at about 6 a.m. the next day.

It is important that you are on time for your appointment. Please report to the front doors of Sanford Medical Center approximately 10 minutes before your appointment. If you are running late, cannot keep this appointment or have any questions or concerns, please call the Sleep Disorder Center at (701) 323-8500 or (800) 932-8758 extension 8500.

Thank you for your cooperation. Together we will make your test as comfortable as possible.

What to Bring

Here are some items you will need to bring to your sleep study appointment:

  • Sleeping clothes, as you may be more comfortable in your own clothes (we do have patient gowns available).
  • Medications you take routinely including over the counter medicines like Tylenol, Ibuprofen, TUMS, etc. If you feel you’ll have difficulty sleeping in a new location, contact your physician for a sleep aid.
  • A special pillow and/or blanket, if you think this will help you sleep better (we do provide pillows and blankets).

After Your Sleep Study

Follow-up is a vital component to determine the effectiveness of treatment. After treatment, your physician may order another sleep test to assess if your sleep has improved.

Most insurance companies will cover the cost of sleep lab studies. However, patients are usually advised to call their insurance company to verify payment.


Sanford's A.W.A.K.E. support group is for individuals affected by sleep apnea. Family members and friends are welcome to attend.
