Sleep Studies

An initial evaluation by our sleep specialist and an overnight sleep study at our sleep disorder laboratory may be all that’s needed to determine the treatment plan that’s right for you.

Sleep studies are tests that measure how well you sleep and how your body responds to sleep problems. These tests can help your doctor find out whether you have a sleep disorder and how severe it is. Sleep studies are typically conducted in a sleep lab where you will spend the night. A technologist will apply various electrodes and sensors to points on your body which provide the measurements your doctor will review the following day. There is no pain or discomfort associated with these sensors since they are all applied to the surface of your skin or over your clothing. You will then be escorted to a private bedroom where you will sleep that night. A technician will monitor you on a video camera all night while also monitoring and recording your biological signals on a computer system. This overnight recording will then be delivered to your doctor for an interpretation of the data. Your doctor will review the results with you and recommend any treatment if the results are positive.

Sleep studies are important because untreated sleep disorders can raise your risk for heart disease, high blood pressure, stroke, diabetes and other medical conditions. Sleep disorders also have been linked to an increased risk of injury, such as falling (in the elderly) and car accidents. Most sleep disorders can be treated.

Johnston Health can perform sleep studies at our sleep labs in Smithfield and Clayton. Talk with your doctor if you snore regularly, feel very tired while at work or school most days of the week, have trouble falling or staying asleep, or if you wake up too early and aren’t able to go back to sleep. These are common signs of a sleep disorder and Johnston Health might be able to help.
