Sleep Disorders Laboratory - Frequently Asked Questions

1. What is a sleep study?

A sleep study is a diagnostic test where the patient sleeps overnight in the sleep lab, allowing the measurement and observation of your sleep, breathing, and movement.  Sensors are applied to your scalp, under your chin, on your legs and chest to measure brain waves, heart rate, leg movements, and eye movements while you're sleeping. A sensor is placed by your nose and mouth to measure airflow. Belts are placed around your rib cage and abdomen to measure breathing movements. A clip is placed on your finger to measure your blood oxygen levels.  There are no needles and no pain.

2. What disorders can be diagnosed in a sleep lab?

The sleep study allows us to diagnose many sleep disorders including obstructive sleep apnea.

3. How do I prepare for the sleep study?

Please do not nap the day of the sleep study or consume caffeine or other stimulants the day of the sleep study.  We would like you to have no problems falling asleep in the sleep laboratory.

Please bring your routine medications to the sleep lab. Please provide us with a list of all your medications (names and doses) that you normally take as well.

Please bring your pajamas as well.

4. Who will be performing the sleep study?

Our certified Sleep Technicians will set up the study and answer all questions you may have. They will monitor you in the lab while you sleep.

5. What time do I have to come to the sleep laboratory and what time will you wake me up?

Please arrive 15 minutes before your schedule appointment. The sleep technician will discharge you from the sleep lab at 6 a.m.
