Ramp Start This displays the Ramp starting pressure. You can increase or
decrease the Ramp starting pressure in 0.5 cm H2O
increments. This is only available if Ramp time has been set to
>0 and therapy pressure >4 cm H2O.
Note: Depending on the therapy mode, the therapy pressure
setting could be CPAP pressure, CPAP-Check pressure, Auto
min pressure, EPAP pressure, or EPAP min pressure.
Flex This screen displays the comfort mode setting. You can select
None, C-Flex, or C-Flex+ (if in CPAP or CPAP-Check mode).
You can select None, C-Flex, or A-Flex (if in Auto-CPAP or
Auto-Trial mode).
Flex Setting You can modify the Flex setting (1, 2 or 3) on this screen if you
enabled Flex. The setting of “1” provides a small amount of
pressure relief, with higher numbers providing additional relief.
Flex Lock This enables you to lock the Flex setting if you do not want the
patient to change it.
Rise Time Rise time is the time it takes for the device to change from
EPAP to IPAP. This screen allows you to adjust the rise time
so you can find the desired setting. This is only available if
Flex has been disabled and the device is in Bi-level or Auto Bi-
level mode.
• 0 (off) reduces the Rise Time feature to the lowest setting
(off = 150 msec).
• 1 sets Rise Time to 1 (200 msec).
• 2 sets Rise Time to 2 (300 msec).
• 3 sets Rise Time to 3 (400 msec).
Rise Time Lock This enables you to lock the Rise Time setting if you do not
want the patient to change it.
Tube Type This setting allows you to select the correct size diameter
tubing that you are using with the device. You can choose
either (22) for the Philips Respironics 22 mm tubing, or (15) for
the Philips Respironics 15 mm tubing. When using Heated
Tubing, the device will automatically change this setting to the
appropriate tubing type (15H).
Tube Type Lock This enables you to lock the Tubing type setting for either the
15 mm or the 22 mm tubing if you do not want the patient to
change it.
