Ramp
Designed to make the beginning of treatment more comfortable, ramp is available in all modes.
In AutoSet mode, ramp time defines the period during which the pressure gradually increases from
a lower more comfortable start pressure to the minimum treatment pressure before the
auto-adjusting algorithm commences.
In CPAP mode, the pressure increases from a low pressure (Start Pressure) to the prescribed
treatment pressure.
Ramp Time can be set to Off, 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device
will detect sleep onset and then gradually increase from the start pressure to the minimum
treatment pressure at a rate of 1 cm H
detected, the device will reach the target pressure within 30 minutes.
Expiratory Pressure Relief
Designed to make therapy more comfortable, Expiratory Pressure Relief (EPR) maintains optimal
treatment for the patient during inhalation and reduces the delivered mask pressure during
exhalation.
EPR
On—EPR is enabled.
Off—EPR is disabled.
The following settings are only available if EPR is On:
EPR Type
Full Time—If set to Full Time, EPR is enabled for the whole therapy session.
Ramp Only—If set to Ramp Only, EPR is only enabled during ramp time.
EPR Level
1, 2, 3 cm H
When EPR is enabled, the delivered pressure will not drop below a minimum pressure of 4 cm H
(4 hPa), regardless of the settings.
