The sleep lab has comfortable, private bedrooms where you will spend the night. You’ll be asked to arrive at the sleep center in the early evening and stay overnight. Once you’ve settled in your room, sensors will be placed on your head, face, chest, and legs.
These sensors are connected by wires to a computer, which monitors your brain waves, heart rate, breathing pattern, and blood oxygen level throughout the night. You may also have a sensor placed under your chin to measure snoring and other noise you make as you sleep. The technologist will monitor your sleep from another room and will wake you up in the morning.
You will be asked to sleep in different positions during the study so the computer can get a complete picture of your sleep patterns. Most people find the test relatively comfortable, although some may find it uncomfortable to have wires attached to their body.
The polysomnography test usually lasts about eight hours. In the morning, you’ll remove the sensors and return home.
You’ll be given an appointment for a follow-up visit with the doctor who recommended the test. You can return to your usual activities after polysomnography.
If you have any questions about the test or how to prepare for it, please call the sleep center.
