What Is A Polysomnogram (PSG) Test?

A sleep study or polysomnogram (PSG) is a painless test that electronically transmits and records your specific physical activities while you sleep. Your sleep patterns and behaviors are monitored remotely by a trained sleep technologist. The recordings become data that are analyzed by a qualified sleep specialist to determine whether or not you have a sleep disorder. The test can be done at night or during the day.

What Is A Polysomnogram (PSG) with CPAP Test?

A PSG with CPAP sleep test is the same as a standard PSG test, except before you go to sleep you are fitted with a mask that delivers CPAP (continuous positive airway pressure), which is a sleep apnea treatment that involves the delivery of air into the airways through a nasal mask. This helps determine the necessary CPAP pressure required to alleviate apnea.

What to Expect

Your Sleep Technologist will be at our site to greet you when you arrive. After you make yourself comfortable, your Technologist will take a brief history, explain the testing procedure, and answer any questions you may have prior to applying the sensors for your study. This procedure is completely painless and generally takes about 40 minutes to make sure everything is placed correctly.

Once you are fitted with the sensors, you are free to stay in your room where you can relax, catch up on phone calls, enjoy our high-speed internet and cable TV, or read until Lights Out at 11pm. You may bring your own pillow and food/snacks. Sleep Insights offers a private, hotel-like environment with wi-fi and cable TV. While you are asleep, your technologist will make every effort to ensure your comfort. You will be monitored remotely--no one will be in your room watching you.

When the study is done, the technologist will wake you and remove the wires and sensors. You will then be able to take a shower (at certain locations) and be on your way.

At your follow-up appointment, you will receive your sleep study results and discuss them with your provider.
