To get the most accurate results out of your sleep study, we ask that you go about your normal routine as much as possible. However, there are a few tips that you can follow to make the study go more smoothly:

• Try to follow your regular routine
• Avoid napping
• Eliminate the use of caffeine and other stimulants after lunch
• Remove nail polish. You will be wearing a pulse oximeter on one index finger.
• Avoid using hair products that can interfere with sleep recording

You may be advised to limit the use of tobacco products prior to your sleep study. If you are on regular medication, please notify the sleep medicine physician. Some medications can affect sleep study results, so the doctor may recommend for you to temporarily discontinue using the medication.


• All regular prescribed medications
• Insurance card and identification
• Reading material
• Your current CPAP/ Bilevel machine mask (if using).
• Toiletries such as toothbrush, toothpaste, comb, brush, etc.
• Favorite pillow or blanket if desired
• Comfortable pajamas or clothes to sleep in

Although your comfort is ver important, we prefer two-piece pajamas. Nightgowns or one pice pajama sets are not generally considered acceptable and nudity is not permitted.


We ask that you enter through the Emergency Room where our registration staff will get you entered into the system. Once you are registered, the sleep technician will come greet you and show you to your room. It is important that you arrive at or before your scheduled time.
We advise that all patients to eat their evening meal before arriving. The cafeteria is closed overnight, however, there are light snacks and drinks available in the lab.


Once you have become settled in your room, you will be asked to complete some paperwork and change into your bedclothes. The sleep technologist will apply sensors and electrodes to your scalp, face, chest, limbs, and finger. This process will take about an hour. Please be patient and take direction from your technologist. Once the sensors and equipment are in place, you will be able to walk around and use the restroom without assistance.

While you sleep the sensors record your brain activity, eye movements, hear rate, blood pressure, and blood oxygen levels. Elastic belts are paced around your chest and belly. These are used to measure chest movements, as well as strength and duration of inhalation and exhalation.

Your technologist will administer the study from another room, where there is a computer recording the data from your sensors. Sleeping with equipment might be a little uncomfortable, but your technologist will do everything they can to ensure that you are as comfortable as possible.
