What to Expect

at your Sleep Study

What is a Sleep Study?

A sleep study is a painless, non-invasive test that measures your body’s function during sleep for the purpose of diagnosing and treating a sleep disorder. It enables us to determine a treatment plan that will help you sleep well, be refreshed and live a healthier life.

I didn’t think it was going to be easy to be relaxed or even get any sleep. Somehow this staff made me feel comfortable and I made it through without a worry. Thanks Sleep Wellness.

There are 2 components to a Sleep Study

THE FIRST is the diagnostic portion, where we will monitor your breathing, brain wave activity, heart rate, body movements and blood oxygen levels while you sleep.

THE SECOND portion, should your diagnostic test suggest sleep apnea, is to apply CPAP (Continuous Positive Airway Pressure) in the lab while you sleep. This “titration” study is to determine the best settings for CPAP therapy, should you require it.

Occasionally, both portions of the test are performed on one evening. However, some patients require a second night for the titration study. Should the diagnostic results indicate you would benefit from CPAP therapy, you will likely be scheduled for a return visit for the titration study.

About your arrival
  • Please arrive no earlier than your scheduled sleep study time.
  • When you arrive, you will ring a buzzer outside of the building and wait for a sleep technician to greet you.


About the staff
  • You will be working with a sleep technician. They will attach the monitoring equipment and observe the data as it comes in through the sensors. They will observe your sleeping habits through an infrared camera and can communicate back and forth with you via an intercom system in case you have questions or concerns during the night.


About your room
  • Each room has a full/queen sized bed with its own bathroom and shower.
  • You will have time to change into comfortable sleep clothes and relax by watching TV before you go to sleep.
  • You will be given access to our Wi-Fi network. If you prefer, you may bring a small electronic to stream programs such as Netflix or Hulu.


About the procedure
  • Sensors will be placed around your head, face, chest, legs, and finger and secured with a washable paste.
  • The sensors do not hurt and will not disrupt your sleep.
  • If the technician confirms that you are showing symptoms of sleep apnea, they will wake you up to initiate use of a CPAP machine. They will then measure the effectiveness of the treatment. You may need to return for another sleep study as this process can require two full nights of data.


About the next day
  • The procedure takes 8-10 hours and will end around 5 o’clock AM.
  • You will be out of the lab no later than 7 o’clock AM.
  • You will be given time to shower and get ready for the day.
  • You will be given some paperwork to complete before your departure
    • One important piece of this is a Patient Satisfaction Survey. We appreciate all feedback and comments regarding your experience. Your comments are confidential and are reviewed by our Patient Experience Committee monthly to implement improvements.
  • We provide you with a dry continental breakfast consisting of muffins, granola bars, etc.


About the next steps
  • Your results will take anywhere from 7-14 days after your study to interpret.
  • Once they are interpreted, we will call you to either schedule an appointment or to share the results with you.
  • If the provider writes a prescription for a CPAP machine, we will contact your insurance right away and follow up with you once we obtain an authorization if that is required.


  • My sales job requires me to drive all over the state. I used to get so tired around 2 or 3 in the afternoon that I’d have to pull over and take a nap. My work suffered, and I worried about falling asleep at the wheel. It turned out I had sleep apnea. Now I use a CPAP machine while I sleep, and it’s made all the difference. I don’t feel like I’m going to fall asleep while driving and I’m a lot more productive at my job.

  • I had to force myself to stay active at my job just so I wouldn’t fall asleep. After work, I’d fall asleep in front of the TV. I never had energy, no matter how much I slept. After my sleep study at the Sleep Wellness Institute, my doctor recommended I use a CPAP machine at night. The treatment turned my life around. I’m in bed less but feel more rested, my blood pressure is lower, and the problems with my ulcerative colitis went away.

  • I just wanted to thank you for your help and fast service today. You were great! I should rest well tonight.
