What to Expect


Diagnosis and Treatment

Having a sleep study is not much more complicated than falling asleep. Our rooms are quiet, comfortable, and free of distractions to promote sleep. After evaluation and testing, results will be recorded and reviewed by a physician.


Preparing for Your Sleep Study

When you arrive you will be greeted by one of our Sleep Technologists. Please complete the enclosed forms and bring them with you to your visit. If you need assistance in filling out the Medical History and Sleep Questionnaire forms, the Sleep Technologists will assist you. We will bill your insurance company for you. Please bring your insurance card with you as we will need to make a photocopy of your card.

The Sleep Center is located at 2204 Eastland Drive, in Bloomington Illinois. This is two blocks East of Veterans Parkway and OSF St. Joseph Medical Center in the Mclean County Neurology Building. Please enter through the main entrance and take the elevator to the lower level.

What to bring for your stay

You will want to bring something comfortable to sleep in, a tee shirt and a pair of shorts would be fine. You will also want to bring any personal items that will make you more comfortable, such as a favorite pillow or stuffed animal. Complete private bath facilities are available and personal toiletries, should you forget something. Do not discontinue any prescription medications unless directed by your physician.

After completion of the brief registration process you will be shown to your bedroom and asked to change into your sleep clothes. The Technologist will then begin the set up procedure. Various sensors will be attached to your body to monitor brain waves, eye movements, muscle activity, respirations, snoring, heart rate, leg movements, and blood oxygen saturation. These sensors are non-invasive and painless to attach. You will be monitored throughout the night. The Technologist may ask you to turn on your side or back during the night. Studies are usually done by 6:30 am the following morning.

If the first portion of the test indicates that you have Obstructive Sleep Apnea we will, time permitting, initiate treatment. This treatment is Nasal CPAP, (Continuous Positive Airway Pressure). This involves wearing a small mask over your nose that delivers pressure to keep your airway open. The technologist will control the amount of pressure remotely. This pressure will gradually be increased throughout the night to eliminate all snoring and apnea, and to normalize the oxygen saturation in your blood. We will make every attempt to accomplish this while you are here. Sometimes it is necessary to return another night to complete the CPAP portion of your test.

You will receive the results of your Sleep Study from your physician. We will send those results to your physician within 7 business days.

If you have any questions or concerns please do not hesitate to call us at (309) 662-1558.

We look forward to seeing you at your appointment and thank you for choosing the Sleep Center of Central Illinois!
