Most sleep centers require that patients complete a sleep questionnaire about their sleeping habits, the day's events, medications taken, and so on. This may occur before your sleep study or shortly after your arrival at the sleep center. After you check-in and get your belongings settled, a polysomnographic technician will ask you to change into your nightclothes or a hospital gown. Small sensors or electrodes will then be attached to parts of your head and body.
Flexible wiring is attached to the sensors, which is then connected to a central unit.
A monitoring area is located close to your room. Once all of the sensors, electrodes, and belts are attached, the technician will take some initial readings while you are awake. More or fewer characteristics may be studied depending on your symptoms. This reading shows the technician which sleep stage you are in. Airflow - A sensor placed on your upper lip monitors the airflow and temperature from your nose and mouth.
