ResMed AirCurve 10 VAuto BiLevel Machine with HumidAir

The ResMed AirCurve 10 VAuto with HumidAir is an auto-adjusting Bi-Level (BiPAP) machine that uses two pressure settings for the treatment of sleep apnea. What is the difference between CPAP and Bi-Level? A CPAP machine uses one pressure setting to keep the airway open and stable while Bi-Level uses two; one for inspiration and one for expiration. The AirCurve V Auto not only allows two pressures but uses an auto-adjusting algorithm to deliver these pressures based on the user's therapy needs.
