• Bi-Flex - The Bi-Flex comfort feature allows you to adjust the level of air pressure relief that you feel when you
exhale during therapy. Your home care provider can enable, lock or disable this feature. When your provider
enables Bi-Flex, a level will already be set for you on the device. If this is not comfortable, you can increase or
decrease the setting. The setting of “1” provides a small amount of pressure relief, with higher numbers providing
additional relief. If the provider has disabled this feature, this setting will not display.
note:
This same setting is also available under the “Setup” screen.
• Rise time - The Rise time comfort feature is the time it takes for the device to change from EPAP to IPAP. If
Rise time is prescribed for you, you can adjust the Rise time from 0 to 3 to find the setting that provides you with
the most comfort. A setting of 0 is the fastest Rise time, while 3 is the slowest. This setting will not display if your
provider has not enabled Rise time on your device.
note:
This same setting is also available under the “Setup” screen.
