Adjusting to Therapy
If you are a first time user, you might need some time to get used to therapy. This is not unusual as it
takes most patients 1~2 weeks to adjust to the most comfortable pressure. The following features will
help you get used to therapy.
Setting the Ramp Time
1. On the Home screen, rotate the control wheel to the
RAMP menu and press the control wheel to enter the
RAMP screen
2. Rotate the control wheel to select the ramp time and
press the control wheel to confirm the selection.
NOTE: When the ramp feature is enabled, the ventilator
outputs an initial pressure and slowly increases the initial
pressure to the therapeutic pressure during the predefined
ramp time to help you fall asleep. When the ramp time ends,
the ventilator automatically detects the patient's respiration
conditions and adjusts pressure accordingly.
Changing the Humidity Level
The level of humidity can be set before or after cure. The value ranges from 1 to 6, or it can be set to Off.
1. Rotate the control wheel to the Humidity
Level menu and press the control wheel
to enter the Humidity Level screen.
2. Rotate the control wheel to select a
humidity level and press the control wheel
to confirm the selection
3. (When Humidity Level is not set to Off) Before treatment, press and held the control wheel for
3s. If the ventilator is not in Warming Up or Cooling Down state, the temperature and humidity
levels of the humidifier are increased. If the ventilator is in Warming Up state, the temperature
