Ramp Start Setting
The device is equipped with an optional ramp feature that your
home care provider can enable or disable. This feature reduces the
air pressure when you are trying to fall asleep and then gradually
increases (ramps) the pressure until your prescription setting is
reached, allowing you to fall asleep more comfortably.
If ramp is enabled on your device, after you turn on the airow, you
can press the Ramp button on the top of the device. Use the Ramp
button as often as you like during the night. When Ramp is enabled,
the Ramp icon ( ) appears on the Monitor Pressure screen.
The Ramp Start pressure setting can be increased or decreased from
4 to the CPAP setting (if in CPAP therapy mode) or the EPAP setting
(for all other therapy modes).
Rise Time Setting
Rise time is the time it takes for the device to change from EPAP to
IPAP. If rise time is prescribed for you, you can adjust the rise time
from 1 to 3 to nd the setting that provides you with the most
comfort. A setting of 1 is the fastest rise time, while 3 is the slowest.
Tubing Type Setting
This setting allows you to select the correct tubing diameter size
that you wish to use with the device. You can choose either “22” for
any Philips Respironics 22 mm tubing, or “15” for the optional Philips
Respironics 15 mm tubing. This selection allows you to control the
resistance in the tube to provide the most comfortable pressure
setting.
Note: If the ramp feature is
disabled, nothing will happen
when you press the Ramp
button.
Note: If Flex is enabled, the rise
time setting will be xed at 2.

tubing, the device tubing type
setting must be set to 15. If your
device does not have the tubing
type setting, you must use the
