Sleep Study: What To Expect

Before the study

Before a sleep study can be scheduled, a complete physical examination by your referring doctor may be required.

Your insurance may require pre-authorization, and if so, Chicago Sleep Center will help.

Sleep studies require an overnight stay at one of our sleep centers. Our centers offer various testing room environments from the standard room to luxury hotel rooms. We also offer sleep studies in the comfort of your own home.

What to expect during and after

The sleep study consists of monitoring airflow from your nose and mouth, heart rate, leg movement, muscle movement, brain waves, oxygen levels, and eye movement.

Electrodes will be placed on your scalp, chest, and legs by a trained sleep technician.

During the sleep study, no one will watch you sleep. Your sleep will be monitored by computers.

The entire study is outpatient and is painless.

The study will be interpreted by a physician board-certified in sleep medicine.

A full analysis will be submitted to your physician and will include any necessary information to help treat insomnia, obstructive sleep apnea, snoring, etc. Your physician will advise you on all available options.
