Changes in sleep stage, weight, body position, and other factors can alter a patient’s airway pressure treatment requirements from night to night, hour to hour and breath to breath. At times they may need higher pressure to maintain airway patency, and at times their pressure needs may be lower. ResMed’s AutoSet™ automatic positive airway pressure (APAP) devices monitor a patient's airway on a breath-by-breath basis and deliver only the pressure that patients need—when they need it.
