Therapy Mode Features

The device has several additional features that enhance patient comfort.

Flex Comfort Feature

The device consists of a special comfort feature called Flex. The device provides the Flex feature in CPAP mode and S mode. This feature is only available when Auto-Trak is enabled.

C-Flex

When in CPAP mode, if C-Flex is enabled, it enhances patient comfort by providing pressure relief during the expiratory phase of breathing. In the following diagram, the dashed lines represent normal CPAP therapy in comparison to the bold line representing C-Flex. C-Flex levels of 1, 2, or 3 progressively reflect increased pressure relief.

		TIME

C-Flex pressure relief is determined by the C-Flex setting and the amount of patient flow. C-Flex returns to the set pressure by the end of exhalation, when the airway is most vulnerable to closure.

Note: Flex is not available if AVAPS is enabled or if an active circuit is used.

Note: The patient has access to this setting, if Flex is enabled.

Note: C-Flex is not available if CPAP is set to 4 cm H2O.

Note: C-Flex, Bi-Flex and AVAPS are intended for use by adult patients.
