The AirCurve 10 Auto BIPAP machine includes two pressure level settings: a higher pressure when you inhale, and a lower pressure that makes it easier to exhale. This ResMed VPAP machine will adjust pressure depending on your needs throughout the night, increasing pressure when you're having an apnea, and allowing you to operate your device at the lowest pressure setting possible for your therapeutic needs. The new Humidair heated humidifier comes as a part of the machine.
