Available Therapy Modes
The table below describes the therapy modes available on the
device:
Therapy Modes Description
CPAP Continuous Positive Airway Pressure; CPAP maintains a constant level of
pressure throughout the breathing cycle.
S Spontaneous Pressure Support; A Bi-level therapy mode where breaths
are patient-triggered and patient-cycled. The device triggers to IPAP
(Inspiratory Positive Airway Pressure) in response to spontaneous
inspiratory eort and cycles to EPAP (Expiratory Positive Airway Pressure)
during exhalation. The device also cycles a patient-triggered breath if no
patient exhalation eort is detected for 3 seconds. The level of Pressure
Support delivered is determined by the dierence between the IPAP and
EPAP settings (PS = IPAP - EPAP)
S/T Spontaneous/Timed Pressure Support; A Bi-level therapy mode where each
breath is patient-triggered and patient-cycled or machine-triggered and
machine-cycled. S/T mode is similar to S mode, except that the device also
triggers machine-triggered breaths based on a set breath rate and cycles
machine-cycled breaths based on a set inspiratory time if the patient does
not spontaneously breathe within a set time.
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 in S
mode only. 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 reect increased pressure relief that
will take place at the end of inspiration and at the beginning of
expiration.
WARNING
The Bi-Flex feature is for adult
patients only.
