Positive airway pressure (PAP) therapy is a generic term applied to all sleep apnea treatments that use a stream of compressed air to support the airway during sleep. With PAP therapy, you wear a mask during sleep. A portable machine gently blows pressurized room air from into your upper airway through a tube connected to the mask. This positive airflow helps keep the airway open, preventing the collapse that occurs during apnea, thus allowing normal breathing. For optimal improvement, it’s important to use your PAP machine every time you sleep – including naps.
Overall PAP therapy is a safe and effective treatment, however there are a few counter-indications. Be sure to tell your doctor if you have bullous lung disease, pneumothorax, cerebrospinal fluid leak or severe epistaxis (nosebleeds).
