What Is A Polysomnogram (PSG)?
A polysomnogram (PSG) is a sleep study that helps determine whether or not you have a sleep disorder. While you sleep, sleep patterns and behaviors such as brain waves, heart rate and breathing, eye and leg movements, and the oxygen level in your blood are recorded. A PSG can be done at night or during the day and a trained sleep technologist supervises the sleep study.
What Is A Polysomnogram (PSG) with CPAP?
A PSG with CPAP sleep study is the same as a standard PSG, except before going sleep you are fitted with a mask that delivers CPAP (continuous positive airway pressure). CPAP is a sleep apnea treatment that delivers mild air pressure into the airways through a mask which keeps the airway open while you sleep. This helps determine the necessary CPAP pressure required to alleviate your apnea.
What to Expect
When you arrive for your sleep study, your sleep technologist will be at the site to greet you and show you to your room. After you make yourself comfortable, your technologist will take a brief history, explain the study process, and answer any questions you may have.
The technologist will then begin the process of applying sensors to your legs, chest and abdomen, using stickers to affix leads. This procedure is completely painless and generally takes about 40 minutes to make sure everything is placed correctly. Next, your head will be marked and measured with a paper ruler and a grease pencil. This is done because each electrode on your head needs to be in a precise location. Once this is complete, a prep solution will be applied to clean the scalp for the electrodes. Lastly, the electrodes are placed on the surface of your scalp with a small amount of paste. The prep, paste, and tape are hypoallergenic.
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. Throughout the study, your technologist will monitor your sleep, but will be available to ask questions and ensure you’re comfortable.
When the study is done in the morning, the technologist will wake you and remove the wires and sensors.
Sleep Insights offers a relaxing environment with private, hotel-like rooms, WI-FI and TV. At certain locations, a shower may be available.
At your follow-up appointment, you will receive your sleep study results and discuss them with your provider.
