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 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 wifi and 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.

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

For the most accurate testing:

  • Wash your hair thoroughly but do not use conditioners or other hair products
  • Remove any hair weaves or extensions
  • If you have acrylic nails, remove an index fingernail for the oxygen reading
  • Plan to be at our center from approximately 7:00-9:00 pm until 5:00-7:00 am the next morning for nighttime testing, or from approximately 7:00 am until 5:00 pm for daytime testing
  • Bring comfortable, loose-fitting, two-piece pajamas to sleep in (we will be placing sensors on your legs and chest). Once the sensors are applied you will be able to move about, use the restroom or get a drink.
  • Bring – and take – all of your normally scheduled medications unless otherwise directed by your doctor or the staff at Sleep Insights
