Setting Ramp
If the patient experiences difficulty falling asleep with full pressure, they may wish to make use
of Ramp where the pressure starts very gently and slowly increases to the set treatment
pressure over a selected time period (see "Setup menu: Options" on page 42).
The Treatment screen following shows Max Ramp set at 15 minutes, while the graph shows
the pressures experienced during ramp while in bilevel mode.
CAUTION
EPAP/PEEP and Pressure Support achieve their configured values at the end of the ramp
period. Some patients require full support from the commencement of therapy. Ramp
may not be appropriate in such cases.
