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

Inhalation Exhalation
C-Flex pressure relief is determined by the C-Flex setting and the
amount of patient ow. 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.
