Your sleep test will be conducted by a sleep technologist in our comfortable and homelike bedroom setting. The technologist, who will be in a separate room from you during the testing, will show you the equipment and explain the procedure. The specialized equipment is used to track many body functions, including brain wave activity, breathing, heart rate, blood oxygen concentration, leg and chin muscle activity, eye movement, snoring and body position. Recording sensors are placed on the skin surface to record this activity. You may have to wear a positive airway pressure device, which is a mask that fits around your nose or nose and mouth.
