Dr. Clarence G. Glenn Sleep Center

What is a Sleep Study?

A sleep study, or polysomnogram, monitors heart rate, movement, breathing, snoring, and oxygen level during each stage of sleep. These measurements are collected and reviewed by sleep specialists to determine if you have sleep apnea, insomnia, narcolepsy or another sleep disorders, so that appropriate treatment can be determined.

What happens during a Sleep Study?

Small button-like electrodes are placed on various parts of your head and body. While you sleep, you will be constantly observed by a technician to assess how loudly you may snore, how you move, and other patterns.

Each sleeping room in the Dr. Clarence G. Glenn Sleep Center resembles a bedroom in a home-like comfortable atmosphere. Sleep as you usually do at home. This will yield a large amount of data to help evaluate your sleeping patterns.

In the morning, you may be asked to fill out a questionnaire about how well you slept that night. If additional information is needed, you may be asked to spend a second night.

How does a Sleep Study Help?

After the sleep study is conducted, a large amount of data is collected and reviewed by a sleep specialist who shares the information with your physician.
