User Manual
Ramp A feature that may increase patient comfort when therapy is started.
e ramp feature reduces the pressure and then gradually increases
(ramps) the pressure to the prescription setting, so you can fall asleep
more comfortably.
Respiratory Rate (RR) e patient’s rate of respiration.
Rise Time e time it takes for the device to change from EPAP to IPAP. You can
adjust this time for your comfort.
Spontaneous (S) is is a bi-level mode which responds to both your inhalation and
exhalation by increasing pressure when you start to inhale and decreasing
pressure when you start to exhale. ere is no automatic delivery of a
breath if you do not inhale.
Spontaneous/Timed
(S/T)
is is an optional bi-level mode which responds to both your
inhalation and exhalation by increasing pressure when you start to
inhale and decreasing pressure when you start to exhale. If you do
not start inhaling within a set time, the device automatically starts
inhalation. When the device starts inhalation, it controls the time
of inhalation and automatically decreases the pressure for exhalation
within a set time.
Standby State e state of the device when the device is on, but the airflow is off.
Tidal Volume (V
T
) e volume of each breath.
Timed (T) is is an optional bi-level mode in which the device controls both
inhalation and exhalation independent of spontaneous breathing.
3.2 What is Bi-level ventilation?
Bi-level ventilation with the device helps you to breathe by supplying two levels of air pressure. e device
provides a higher pressure—known as IPAP (Inspiratory Positive Airway Pressure)—when you inhale, and
a lower pressure—known as EPAP (Expiratory Positive Airway Pressure)—when you exhale. e higher
pressure makes it easier for you to inhale, and the lower pressure makes it easier for you to exhale.

You can adjust the Rise Time to make the pressure change more comfortable.
e device can also provide a single pressure level, known as CPAP (Continuous Positive Airway Pressure).
