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.
PRESSURE Inhalation
CPAP
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.
