Stanford Center for Sleep Sciences and Medicine

Unhealthy sleep and sleep deprivation are linked to heart disease, depression, obesity and lower life expectancy. Seventy million people suffer from chronic, severe sleep disorders in the United States alone. These include difficulties sleeping at night, problems with excessive daytime sleepiness, or other medical problems that may occur or be exacerbated during sleep.

Care and Treatment for Sleep Disorders

How to Prepare for Your Overnight Sleep Study

An overnight sleep study, also called a polysomnogram, is a procedure which monitors body functions such as brain waves, heart rate, leg movements and breathing during sleep. You will be monitored by a sleep technologist all night long. There are different types of sleep studies. Diagnostic studies are used to evaluate whether you have a sleep disorder. A CPAP (a mask worn over the nose) study is performed to determine the ideal pressure settings.

A technologist will greet you at approximately 7:00 pm in the waiting area of the lab and will show you to your bedroom. It is important that you arrive on time! Be sure to eat before you arrive.

Once you are settled in your bedroom, you will change into your bedclothes and complete some paperwork. Then the sleep technologist will apply electrodes and sensors which takes about an hour. Sensor attachment will be done utilizing collodion (a glue-like substance) and medical tape. Please prepare for this process by thoroughly washing your hair before your visit to our lab. After the sensors are in place, you will be able to walk around the bedroom and use the restroom unassisted.

You may go to sleep at your normal bedtime within the constraints of the lab protocols. Keep in mind, the earlier you go to bed, the more time we have to evaluate your sleep. Some patients will use CPAP during the night.

During the night, a technologist will be available to assist you as needed.

Typically, we begin waking patients at 6 am, unless a later or earlier wake up time is desirable. Please keep in mind that the equipment takes approximately 20 minutes to remove.

There is a shower available to wash up after all of the sensors have been removed.

  • Appropriate bedclothes (preferably two-piece pajamas). Nightgowns and one-piece pajamas sets are not acceptable attire, and nudity is not permitted.
  • If you use a CPAP/Bilevel machine bring your current mask. If you do not know your current pressure or have been instructed by your sleep physician, bring your CPAP/Bilevel.
  • Any medications you may need during the night of the study in the original medication container. Prescription and non-prescription medications are not dispensed at the Sleep Center.
  • Personal toiletries (toothpaste, toothbrush, comb, brush, shampoo, etc.), and a change of clothes for the next day. The lab provides towels and bedding (but no toiletries) and there is a bathroom in each room. Showers are available in most rooms.
  • Reading material, a movie to watch or a laptop (DVD players and Wi-Fi available).

Who can stay with me?

For adults, limited family members/friends (1-2) are welcome to accompany you until your bedtime. Guests are not permitted to stay overnight.

For children under 18 years of age, disabled, or otherwise non-independent patients, we require and allow only one parent or caregiver to stay overnight. A recliner is available in the room for the caregiver to sleep. Sharing the bed will interfere with the sleep study.

What about food?

Please eat before you arrive. You may bring snacks and drinks for refreshments. The cafe is closed overnight, but there are vending machines are available on the ground floor.

Meal service is only provided for patients scheduled for daytime nap testing (MSLT or MWT). Please be sure to eat dinner prior to arrival at 7:00PM.

How much will this cost?

If you have an HMO plan, you must have your referral and authorization approved by your primary care physicians in advance of your scheduled appointment.

It is your responsibility to know your insurance coverage and benefits. Call the customer service number on your insurance card and ask for eligibility for benefits. You will need the CPT codes below when inquiring about coverage.

What happens next?

You will receive the sleep study report in the mail 2 weeks after your sleep study. If you do not receive the report, please call (650)723-6601.

You should follow up with a doctor to discuss the results. If a Stanford Sleep Center doctor ordered the sleep study, please call us at (650)723-6601. Otherwise call your referring physician.

Other Frequently Asked Questions about the test procedure

Why record all of these things?

These parameters are recorded to obtain objective information about the quality of sleep to better define your sleep problem.

How can I sleep with all of these things on me?

The body sensors are applied in a manner that will allow you to turn and move during your sleep. Generally, you will not be aware that you are wearing the devices after they have been on for a short time. The lab technical team makes the environment as comfortable as possible, within the constraints of a monitored setting.

Will the sensor devices cause discomfort?

Sometimes, in preparing the sites for sensor application, there are mild temporary irritations; please inform us if you have any known sensitivity to particular tapes or if you have a latex allergy.

Do all rooms have a double bed and private restrooms?

At the Stanford Sleep Medicine Center, we see all types of patients so our bedrooms and restrooms are arranged differently to allow for maximum flexibility to accommodate pediatric cases, bariatric patients and individuals with disabilities. As a result, some bedrooms have double beds and some rooms have single beds. All of the bedrooms have private restrooms and the majority include a shower. We are unable to guarantee specific room profiles, though we do our best to make all rooms as comfortable as possible.

Can I use my own CPAP/BiPAP machine?

During a sleep study, information about your CPAP/BiPAP pressure is recorded as part of your sleep study, therefore lab machines are used. Your physician may instruct you to bring your mask and equipment to your appointment to check the pressure setting.

Can I smoke?

No smoking is allowed on the premises or anywhere on the Outpatient Campus.

Clinical Trials

The Stanford Center for Sleep Sciences & Medicine has a robust, multi-disciplinary research program with several areas of focus that range from seeking the genes associated with sleep disorders, to studying the neurological and chemical systems that regulate sleep and waking, to conducting clinical trials of promising new methods to treat sleep disorders.

We regularly have new clinical studies opening across a wide number of medical specialties. If you would like to be contacted if/when such studies become available, please complete this secure, on-line survey.

When a study involves human subjects the researchers must carefully evaluate what type of individuals should participate in the study and develop inclusion and exclusion criteria to ensure appropriate individuals are enrolled. These criteria are devised for safety purposes and to ensure that the researchers will be able to devise conclusions based on the data collected. Each study has a study coordinator who works with the principal investigator to evaluate whether a person meets eligibility criteria.
