A Positive Airway Pressure (PAP) Nap is a daytime study for patients who have anxiety about starting PAP therapy or are having difficulty tolerating it for their sleep-related breathing disorder. The PAP nap usually last between one-three hours. The Pap Nap gives you the opportunity to try several masks on to find the right fit and size as well as try different pressure settings to receive the most benefit from your device. You will work with a sleep technologist, using relaxation, deep breathing and desensitization techniques to try to become more comfortable with PAP therapy during this session.
