Why do I need a sleep study?
In order for us to fully evaluate your sleep and any potential sleep disorders, an all-night sleep test, also called a polysomnogram (PSG), may be done. The test records brain waves, breathing, heart rate, oxygen, muscle tone and other functions. After the study, a sleep specialist will review and interpret the record to help you and your health care provider understand your specific sleep disorder. Treatment recommendations will be made when your medical history and the results of your physical examination and sleep test have been reviewed.
What can I expect?
Many people expect a sleep center to be cold, bright, technical and impersonal-looking. At Lahey Clinic’s Sleep Center, the surroundings are homey and comfortable, similar to a hotel room.
When you arrive at the Center – usually between 5:30 PM and 9:30 PM – the technician will greet you and show you to your bedroom. You will be shown the equipment that will be used and given a chance to ask questions. You should inform the technician of any changes in your sleep or specific difficulties you have not already discussed with your health care provider. Your wake-up time will also be confirmed.
While you are sleeping, various important body functions and measurements are recorded. The technician will monitor your sleep throughout the night from a nearby room. Electrode wires will be gathered together behind your head so you can roll over and change positions.
