What is EPAP?
Provent Sleep Apnea Therapy utilizes a proprietary MicroValve technology developed by Ventus Medical. The device attaches over the nostrils with a hypoallergenic adhesive. During inhalation, the valve opens, allowing the user to breathe in freely. When exhaling, the valve closes and air passing through the nose is directed through two small air channels. This increases the pressure in the airway (called EPAP or expiratory positive airway pressure). This maintains pressure in the airway until the start of the next inspiration and helps to keep it open.
