Similarity To Other Tests
An electrocardiogram is similar except wires in sleep studies allow you to sleep peacefully, in any position you want. There is no discomfort.
Sleep Studies
Sleep studies require an overnight stay at Capitol Sleep Center. You may be required to stay at Capitol Sleep Centers during the day on day two of your study. If you are, you will be asked to take a series of twenty minute naps, two hours apart. We will be analyzing the degree of sleepiness you exhibit during the day in relationship to nighttime sleepiness. The daytime study ends at approximately 4:00 PM.
Lab Studies
Several measurements are recorded while you sleep at Capitol Sleep Centers. The measurements may include brain wave activity, heart function, respiration, and/or leg and eye movements. All measurements are taken from the surface of the skin with no discomfort to you.
While You Are Our Guest
You will need to bring with you pajamas, bathrobe, slippers, and personal hygiene items.

For daytime test, patients may bring in any snack or breakfast item they wish. Lunch will be provided. If you are on a special diet, you may want to bring your own food. We have a refrigerator and a microwave for your use.

Your comfort is the main concern of our well-trained and friendly staff. We encourage you to bring your own pillows if you are more comfortable using them.
