Bi-level ventilation with the device helps you to breathe by supplying two levels of air pressure. Th e device
provides a higher pressure—known as IPAP (Inspiratory Positive Airway Pressure)—when you inhale, and
a lower pressure—known as EPAP (Expiratory Positive Airway Pressure)—when you exhale. Th e higher
pressure makes it easier for you to inhale, and the lower pressure makes it easier for you to exhale.
You can adjust the Rise Time to make the pressure change more comfortable.
