What is a Sleep Study?
A Sleep Study is often referred to as a “polysomnograph.” There are two types of sleep studies for diagnosing Sleep Apnea. We offer both Home Sleep Testing and In-lab Sleep Testing.

In-lab Sleep Testing
A night in our Sleep Disorders Center is necessary for evaluation of physical factors affecting sleep. Restless Leg Syndrome (RLS), Periodic Limb Movement Disorder (PLMD), or Obstructive Sleep Apnea (OSA) are the main disorders found during the sleep study – however, there are many other disorders the test can detect.
The good news is that a sleep study has no needles involved and is painless. You will be assigned to a testing area that is set up much like a hotel room rather than a hospital room. You will have a private room with a bathroom, TV, recliner and comfortable bed.
After you check in and get your belongings settled, a polysomnographic technologist will ask you to change into your nightclothes or a hospital gown. Small sensors will be attached to your head and parts of your body. Flexible wiring is attached to the sensors connected to a small box. The technologist monitors your sleep from a separate room via a computer system that records the study.
While you are asleep, the sensors monitor and record various physical activities such as:
- Brain activity
- Eye movements
- Effort to breathe
- Muscle tone
- Heart rate
- Oxygen levels
- Leg movements
You will also be videotaped while you sleep.
Because of the enormous amount of data collected from your sleep study, the test results will take approximately two weeks to be processed, reviewed and sent to your doctor. Be sure to follow up with your doctor.
