A CPAP uses positive pressure that blows air out of the device into a tube that connects to a mask that seals over the nose or over both the nose and mouth. This positive pressure creates a pneumatic splint to keep the airway open during sleep. Frequent patient complaints include unable to tolerate the mask, unable to tolerate the pressure, too complicated to operate, difficult to clean, and noise and air leakage can bother the bed partner.

​

Unlike CPAP machines, iNAP technology uses negative pressure to move and stabilize the tongue and soft tissues, removing blockage from the airway. The user wears a simple and comfortable oral interface. The console, which is the size of a smartphone is discreet and comes with a built-in rechargeable battery, making it perfect for travel. iNAP is quiet, easy to use, maintain and keep clean, and discreet with no concerns that could bother the bed partner
