Where to Go

The UW Medicine Sleep Center at Harborview is located on the fourth floor of the Ninth and Jefferson Building, 908 Jefferson St. Patients should plan to arrive at 7:30 p.m. You can wait in the Ninth and Jefferson building lobby until 7:30 p.m. when the lab opens.

Parking is available under the building with access to the garage from Terry Avenue between James and Jefferson Streets. Take the elevator to the lobby. The security guard will escort you to the sleep institute. Patients arriving after 9 p.m. will need to park in View Park Garage or along the street. A staff member will check you in and settle you into your bedroom. 

The Study

Your technologist will explain all procedures that will be completed for your study. It will take approximately one hour to apply the sensors. Procedures will include the following:

  • Electrodes will be placed on your scalp, temple and chin to monitor brainwaves and muscle movement during sleep.
  • A snore sensor will be placed on your neck. Electrocardiogram (EKG) wires will be attached to monitor your heart.
  • Two belts will be placed on your abdomen to monitor breathing.
  • Two leads will be placed on your legs to monitor movement.
  • An oxygen sensor will be placed on your finger to monitor oxygen levels throughout the night.
  • An air sensor will be placed by your nose to monitor your breathing during the night.
  • These sensors do not limit your mobility in bed, and are not obtrusive.

If you have questions, please call our office during business hours 206.744.4999.
Throughout the study, the technologist will be available and may be summoned by an intercom device to assist you at any time. Patients may be disconnected, with assistance, from the monitoring equipment anytime throughout the night if they need to use the bathroom or get up out of bed. Your study will be completed by 6 a.m., and you will be free to bathe and depart at this time. Checkout time is no later than 7:00 a.m.

If a CPAP or BiPAP machine may be used during the study, the technologist will explain that process to you during a trial demonstration before bedtime.

No-Smoking Facility

You will not be permitted to smoke at any time, either after checking into the sleep lab or during your study. If this will cause you difficulty during your stay, please discuss nicotine replacement options with your primary care physician. You may want to start your nicotine replacement at least 12 hours before your sleep study.

Special Needs

Technologists in the sleep lab are not nurses and cannot provide help with medications, nutrition, mobility or personal hygiene. If you require ANY assistance with daily activities or tasks, please call our office one week prior to the study so appropriate arrangements can be made.

Preparing for Your Sleep Study

  • Do not consume any caffeine (coffee, tea, cocoa or chocolate) after noon the day of your test.
  • Do not take any naps.
  • Maintain your regular daytime schedule.
  • Your hair should be clean, as electrodes will be placed on your scalp. Clean hair means washed the day of the study. Please do not use hairspray, gel or other hair care products, or you will need to wash your hair prior to starting the study. 
  • Please do not wear make-up. If this is not practical, be prepared to remove your make-up when you arrive.
  • Men, unless you have a beard, please arrive clean-shaven. If you have a beard, we can work around it, but stubble can be difficult to work with in the lab.
  • Hairpieces and hair weaves must be removed. (We must be able to get to your scalp to do the test).
  • Please eat dinner before arriving. No food service is available.
  • If a spouse or friend is driving you from out of town, he or she will need to stay at a local hotel/motel.
  • If a patient is younger than 18, a legal guardian must stay throughout the study.

What to Bring

  • Bring a list of ALL medications you are taking.
  • Bring prescribed medicines with you to your sleep study. The medicines need to be in their original container. You will need to administer your own medication, including insulin.
  • Pack as if you are staying in a hotel for the night – pajamas (cotton is best), robe, toothbrush, toothpaste and shampoo. 
  • You may also want to bring some reading materials. There is a television in each bedroom.
  • You may bring a small snack and decaffeinated beverage. A microwave and refrigerator are available for your use, ask your technologist for assistance.

The Results

Your sleep study results will not be immediately available. It takes time to process the data and analyze the results. You will be contacted several weeks after your sleep study in order to continue the next step in your health care.

Possible outcomes from participating in the study include: a CPAP titration study, a follow-up appointment, a CPAP or BiPAP machine ordered for home use. If a CPAP or BiPAP machine is ordered for you, a homecare company will contact you to arrange machine set-up.

Please call our office at 206.744.4999 if you have any additional questions.
