Before Your Sleep Study
The day of your Sleep Study

After lunchtime (noon), please do not:
  • Consume any caffeine (soda, coffee, tea, energy drinks, chocolate)
  • Consume any alcohol
  • Take any naps
Before you leave home, please:
  • Shower or bathe.
  • Wash your hair.
  • Do not apply hair products, makeup or heavy creams/lotions to your skin - these will cause the electrodes to easily detach from your skin and interfere with the sleep study.
Arriving at the sleep lab:
  • You do not need to arrive early. Please plan to come at the time provided on your confirmation letter.
  • For directions and parking information, please refer to your confirmation letter.

What to Bring to Your Sleep Study

  • Your completed Sleep Diary
  • Your completed Sleep Questionnaire
  • A photo ID card
  • Your insurance card(s)
  • Pajamas or something comfortable to sleep in
    -Two-piece required, please no nightgowns
    -Shorts and short-sleeved tops work the best
  • Bring any other toiletries that you think you will need
Soap, shampoo, towels and washcloths are provided by the sleep lab. Blankets and pillows are provided, but please feel free to bring your own if it will make you more comfortable. 

During Your Sleep Study
When You Arrive at the Sleep Lab

  • Our sleep technologist will collect all paperwork from you and make photocopies of your identification and insurance card(s).
  • The technologist will show you to the private room in which you will spend the night and will attach all monitoring sensors.
  • You will be able to read or watch TV if either is part of your normal sleep routine.
  • No blood work is needed for this test and no medication will be administered. You will be allowed to fall asleep at your own pace and will be awakened by the technologist at approximately 6 the following morning.
  • A continental breakfast is available. 
If you have arranged transportation, please have them arrive no later than 6 a.m.


  • This is a study that looks at your sleep cycles by recording your brain waves. It also looks at your eye movements in sleep, the electrical activity of the muscles, blood pressure, respiratory rate, oxygen levels in the blood and heart rhythms.
  • One of the Sleep Study Technicians will meet you on your arrival.
  • They will tell you what they are going to do and they will attach all the monitoring equipment to you.
  • Your test will be finished at 6:30 am, and you may leave. If you took medication to help you sleep, we prefer you have someone drive you home since the medication may have lasting effects and make it unsafe for you to drive.

Continuous positive airway pressure (CPAP)

  • This may be applied with or without oxygen as required.
  • A small mask is applied to your face, secured with wide elastic straps over your head and tubing plugged into the machine.
  • Many people find the machine quite noisy at first but soon become used to it. This is designed to help your breathing while you sleep.
  • The staff will observe you closely and make pressure changes to find the proper pressure needed to keep your airway open and monitor your oxygen levels and sleep quality.

After Your Sleep Study
Getting your test results

  • After completion of the overnight sleep study, a sleep technologist will review the study and then send it to a physician specializing in sleep medicine, who completes the interpretation. This process is normally completed in seven to 10 business days.
  • These results will be sent to your referring physician.
  • If the first overnight sleep study is positive for Obstructive Sleep Apnea, you will be required to return to the center for the second part of the sleep study process.
  • In addition to making a diagnosis, our interpreting physician may prescribe lifestyle changes, medication or other treatments to help you get the adequate sleep that is essential to your health and peak performance.

What Happens After Your Sleep Study?

Some insurance guidelines mandate that you obtain follow-up appointments to ensure compliance with CPAP therapy, if ordered.

We hope to exceed your expectations. If you have complaints/suggestions, please let us know - you will receive a survey. We value your feedback, so please let us know how we are doing.
