Sleep Evaluation

Many of our patients stay one night at the Sleep Center in order to get a diagnosis. Those who are being evaluated for sleep apnea, however, typically need to spend a second night, at a later date, for treatment. If you are being evaluated for narcolepsy, you will likely spend one night, followed by a series of nap trials the following day. Shift workers can be monitored during the day.

Preparing for your sleep study

  • Bring your toiletries and, if you prefer, your own pillow.
  • Bring your pajamas or loose-fitting clothing (shorts and T-shirt) so that the technologist can apply sensors easily.
  • Shower or bathe and be sure to not wear lotions, hair sprays, makeup, or fingernail polish.
  • Do not take a nap on the day of your evaluation.
  • Sleep well, if you can, the night before.
  • Do not consume alcohol or caffeine after 3:00 p.m. on the day of the test.
  • Do take any medication(s) you are on, unless otherwise instructed by your physician. If you take medication(s) at night, be sure to bring them with you.

During the sleep study

  • Once in bed you will be asked to respond to a set of directions called biocalibrations. This process is done to ensure that the sensors are placed correctly and responding appropriately. After biocalibration, you may be asked to prepare for sleep.
  • You can change your position and request to get out of bed as often as you require. During the night, the technologist in the control room will monitor you via closed circuit television. The technologist will enter the room only if you request it or if it becomes necessary to reapply a sensor. You can request a specific wake-up time. If not, we will wake you between 5:15 a.m. and 6:15 a.m. The sensors will be removed and you will be free to leave.
