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.

There are two 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 (Constant 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.

Before Your Visit

Please follow these steps to prepare for your visit.

  • Eat a normal meal prior to your arrival at our sleep center.
  • If the day of your test is one that you do not work, it is advised that you keep active during the day so that you will not have trouble falling asleep.
  • Make certain to wash your hair and refrain from using any styling products prior to arriving.
  • Please remove any nail polish prior to arriving.

There will be a pulse oximetry monitor on your index finger.

Please Do NOT

  • Do not take any naps the day of your visit.
  • Do not have any alcohol or caffeine within 12 hours of your appointment.

What to Expect

When you arrive at our facility, you’ll be treated with kindness, respect and friendly care. You’ll sleep overnight in a private room, while a trained technologist monitors you. Every room is individually climate controlled. If you find your room to be too hot or too cold, please let the technician know.

Before beginning the study, our sleep technician will provide you with helpful information. He or she will also be available throughout the night to assist you and answer questions.

The technician will place electrodes on your body. These electrodes are painless, but due to the adhesive used with these electrodes, most patients prefer to shower before leaving in the morning. During your sleep study, you will be constantly monitored by our specially trained sleep technicians, both through these electrodes and on a video screen for your safety.

What Happens After My Study

Your sleep study will conclude at approximately 5 a.m. (times will vary for second/third shift studies, but plan on being at our facility for about 8 hours.) If you need to leave earlier to get to work, accommodations may be made. Simply notify your sleep technician when you arrive.

Our highly efficient check-out process will help you get on your way quickly. However, you’re welcome to stay for breakfast or coffee, which will be provided in your room for your convenience.

The Sleep Wellness Institute physician will have (or will provide to your referring physician) a written report within 72 business hours of your sleep study. Either The Sleep Wellness Institute physician or your referring physician will schedule you for a follow up visit to receive your results and treatment recommendations in person.
