Comfort features
Designed to make the beginning of treatment more comfortable, ramp is available in all modes.
In AutoSet and AutoSet for Her 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 VAuto, S, ST and T modes, the EPAP gradually increases from the Start EPAP to the prescribed treatment pressure. Throughout Ramp, Pressure Support is maintained at the same level as that set for treatment.
 |
In ASV and ASVAuto mode, the ramp time defines the period during which the expiratory pressure increases linearly from a lower more comfortable start pressure (Start EPAP) to the minimum treatment pressure (EPAP for ASV mode and Min EPAP for ASVAuto mode) before the auto-adjusting algorithm commences.
During ramp, the pressure support is always at Min PS. After ramp, the pressure support modulates within the PS range (Min PS and Max PS). In ASVAuto mode, the EPAP also modulates within the EPAP range (Min EPAP and Max EPAP).
 |
Note
If ramp is on (set between 5 min and 45 min), Start EPAP has to be set.
In CPAP mode, the pressure increases from a low pressure (Start Pressure) to the prescribed treatment pressure.
Ramp Time can be set to Off or 5 to 45 minutes.
Available in CPAP, AutoSet and AutoSet for Her modes.
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 H2O (1, 2, 3 hPa) |
When EPR is enabled, the delivered pressure will not drop below a minimum pressure of 4 cm H2O (4 hPa), regardless of the settings.
Available in S mode
The Easy-Breathe waveform intelligently recreates a patient’s individual breathing pattern, so breathing feels more natural and therapy is more comfortable.
Available in AutoSet mode.
For patients who are sensitive to faster changes in pressure during therapy, AutoSet Response can be set to either Standard or Soft. If set to soft, patients will receive gentler pressure rises during therapy.
Patients who use the AutoSet Response feature will still get the benefits of ResMed's AutoSet technology including improved sensitivity to flow-limitation and CSA Detection with Forced Oscillation Technique.
