What to Expect at Your Sleep Study

Polysomnography, commonly referred to as a sleep study, observes your breathing, heart rate, body movements, and brain activity during sleep. It is conducted in a specialized environment by a trained sleep technologist who monitors these factors to guarantee your safety and comfort.

Your doctor performs a thorough assessment of your sleep complaints, and if they feel further testing is required, orders a sleep study. This helps to correctly diagnose sleep disorders that you might have.

On the day of the study, you will be asked to arrive at the sleep center in the evening to sleep there overnight. Get tips for preparing for a sleep study, including what to do during the day and what to bring for your overnight stay.

To start the procedure, the technologist will use special glue to attach wires to your head, chin, chest, and legs. Additionally, you will be required to wear soft bands on your chest and abdomen, as well as an oxygen monitor on your finger. Some facilities might utilize a microphone to monitor snoring and have extra audio/video recording devices.

Subsequently, you will be permitted to drift off to sleep as the technologist monitors your sleep metrics using a computer. If you struggle to fall asleep, medication may be administered for assistance. The technologist may apply a mask over your mouth and/or nose to deliver pressurized air for treatment, depending on the specific study prescribed by your doctor.

The technologist might wake you during the night to request a change in your body position or to fix any loose wires. Upon waking in the morning, the technologist will assist in removing the wires and monitors. The data collected during the study will be analyzed by a sleep medicine physician who is board-certified, and a diagnosis will be made accordingly.
