Sleep Study

Why you need a sleep study?

The all-night sleep study is frequently used by sleep physicians to evaluate patients when they are sleeping. This laboratory test is extremely valuable for diagnosing and treating many sleep disorders, including neurological disorders, movement disorders and breathing disorders at night. All-night sleep studies (also called polysomnography) are ordered by Midwest Sleep Institute and are performed in the sleep laboratory.

How are the sleep studies performed

The sleep laboratory is located in Gurnee, IL (map). Patients come to the laboratory between 9 and 9:30 p.m. on the appointed day. There they meet with a sleep technologist, who will explain and perform the study. The sleeping rooms are comfortable, home-like rooms with normal (not hospital) beds. Each room has a television.

Preparation for the study

    1. Please shower before coming into the lab. Shampoo your hair. Do not use hair spray,mousse, etc. in your hair. Ladies please remove all makeup and fingernail polish. Please let the technician be aware of braids, extensions, and hairpieces.
    2. Please rise at your usual time, the day of the test. No naps during the day. For those who work third shift, please contact the sleep lab ahead of time so that arrangements can be made to accommodate your sleep schedule.

Monitoring Process

The technologist monitors the patient’s sleep and general condition. Any problems with the study may be easily dealt with. Patients may easily call the technologist if there is a problem as well.

Patients generally get out from the study around 6:30 to 7 in the morning. However, if an earlier wake-up is needed, the patient just needs to let the technologist know.

After The Study

Once the sleep study is completed, it is scored by a scoring technologist and sent to Midwest Sleep Institute for interpretation. This entire process takes 2 –3 days. Dr. Kagzi will then call the patient and the physician and inform them of the results and an appropriate follow up is arranged.

Sleep studies are generally easy to tolerate, comfortable for patients, and give the sleep physician the information they needs to accurately diagnose and treat the sleep disorder.
