Using the Ramp Feature
The ramp function enables a gradual rise in pressure after turning the device on; that is, the pressure
levels are low at the start of the night to help you fall asleep. You can also use this function if you have
to get up during the night and have difficulty going back to sleep. The pressure “rise time” up to the
final pressures is prescribed by your medical team and the setting carried out by your service provider
is between 0 (no progressive rise) and 30 minutes in 5-minute increments. The ramp may have been
preset to 0 according to the prescription provided by your medical team. In this case, the ramp function
is disabled and pressing the
Ramp button on the front panel of the machine has no effect (Figure 2,
item 3 on page 5).
The initial ramp pressure can be set to a value between 3 cmH
2
O and the Positive Expiratory Pressure
level prescribed by your physician. This function allows you to set the starting pressure level that
enables you to fall asleep.
To access the parameter setting menu, just press for one second the
Information Access button
(Figure 10).
NOTE
This function can be used when the device is in either the standby mode or the operation mode.
