Humidifier Icon and
available Therapy Features
If prescribed for you, the device provides the following therapy features.
Bi-Flex Comfort Feature
If enabled, the device provides a comfort feature called Bi-Flex. The Bi-Flex attribute adjusts therapy by inserting a
small amount of pressure relief during the latter stages of inspiration and during active exhalation (the beginning part
of exhalation). Bi-Flex levels of 1, 2, or 3 progressively reflect increased pressure relief that will take place at the end
of inspiration and at the beginning of expiration.
If enabled, the device is equipped with a linear ramp function. The Ramp feature will reduce the pressure and
then gradually increase (ramp) the pressure to the prescription pressure setting so patients can fall asleep more
Rise Time Comfort Feature
If enabled, the device provides a comfort feature called Rise Time. Rise time is the amount of time it takes the device
to change from the expiratory pressure setting to the inspiratory pressure setting. Rise time levels of 0, 1, 2, or 3
progressively reflect slowed response of the pressure increase that will take place at the beginning of inspiration. A
setting of 0 is the fastest rise time while a setting of 3 is the slowest. Providers should adjust the rise time to find the
most comfortable setting for the patient. Rise time cannot be adjusted when Bi-Flex is enabled.
