Frequently Asked Questions


When should I visit a sleep center?

Consider a sleep study if you have had trouble sleeping for more than a month or if you are tired during the day for unknown reasons. If you have trouble falling asleep or staying asleep, it is important to have the cause evaluated in a sleep lab.


Are sleep studies covered by insurance?

Yes. Most private health insurance companies and Medicare cover office visits, sleep studies and CPAP services.


Do I need a referral?

You do not need a referral if you have Medicare or a PPO. HMOs usually require a referral. You can generally call your doctor and ask him or her to fax the referral.


What are the consequences of not treating sleep disorders?

Sleep disorders can contribute to daytime sleepiness, fatigue, cognitive impairment and poor job performance. More serious consequences of sleep disorders include hypertension, cardiac disease, stroke, anxiety, depression, memory loss and dementia.


What happens during a sleep study?

A sleep study is a noninvasive, painless evaluation of your sleep. Electrodes monitor your brain waves, rapid eye movements, breathing patterns, respiratory efforts, oxygen levels, snoring, muscle tone and leg movements, electrocardiogram and heart rate. Learn more about how a sleep study works in our Health Library.


What if I can't fall asleep during the study?

Nearly everyone is able to fall asleep. It just may take you a little longer than normal.


Can I get up to go to the bathroom?

Yes. The electrodes are collected together to a central attachment that easily detaches to free you to get up and out of bed.


What if I don't usually sleep at night because I work a late shift? What if I prefer going to bed very late or very early?

We can accommodate any sleep pattern.


How long do I have to be at the sleep lab?

Arrival times are flexible. Typically patients arrive between 8 – 10 p.m. Patients are usually with us about 9 hours. We aim to get at least 7 hours of sleep study time.


What should I bring with me?

Pack as though you are going to a hotel. We furnish basic toiletries such as soap, shampoo and toothpaste.
