Programming Ramp Mode
Some users find it comforting to acclimate to CPAP
therapy each session. This can be accomplished by
programming the Ramp Mode which allows you
to start with a low initial pressure and gradually
increase to the prescribed treatment pressure.
Setting Ramp Time
When the
Z1
is in standby mode, press and hold the
Up Arrow Button
for approximately 3 seconds until
the “00 MINUTES” value flashes. While it is flashing,
repeatedly press either the
Up
or
Down Arrow
Buttons
to increase or decrease the Ramp Time in
5 minute increments. (Figure 12) Set the Ramp Time
to “00 MINUTES”” to disable the Ramp Mode.
When the desired Ramp Time value is reached, press and hold the
Start/Stop Button
for
approximately 3 seconds to save your Ramp Time setting (this setting will be saved even when
the
Z1
is not powered). The
Z1
will return to standby mode. To return to standby mode without
saving the new setting, press and release the
Start/Stop Button
momentarily instead of holding it
down.
Setting Ramp Start Pressure
Press and hold the
Down Arrow Button
for 3 seconds until the Ramp start pressure value flashes.
While flashing, repeatedly press either the
Up
or
Down Arrow Buttons
to increase or decrease the
Ramp start pressure by 0.5 cmH
2
O increment. (Figure 11) Ramp start pressure must be lower than
prescribed pressure.
When the desired value for Ramp start pressure is reached, hold down the
Start/Stop Button
for
approximately 3 seconds to save your setting. The
Z1
will return to standby mode. To return to
standby mode without saving the new setting, press the
Start/Stop Button
momentarily instead
of holding it down.
