What is involved in a sleep study?

A sleep study is an overnight observation of your body while you are asleep in our specialized lab to find patterns and/or disruptions in your sleep.

Disrupted sleep from certain conditions can lead to day-time sleepiness and medical complications such as heart disease, stroke and high blood pressure.

During the sleep study, the following areas may be measured with body sensors:

  • Brain waves
  • Heart beat
  • Eye movement
  • Muscle tone and body position
  • Leg movement
  • Breathing
  • Oxygen levels

To see the Sleep Lab, your physician needs to fill out a referral form.

If you have excessive daytime sleepiness, make sure that someone drives you to and from your sleep study. Please advise the booking Staff if you have any allergies, mobility aids (cane, walker or wheelchair), any risk of falls and if you require any special assistance during the sleep study.
