Rise time adjustment

S, ST, T, PAC and iVAPS modes
Rise Time sets the time taken for the device to reach IPAP. The greater the rise time value, the
longer it takes for pressure to increase from EPAP to IPAP.
Patients with a high ventilatory demand may prefer a shorter rise time, while patients who are slow
breathers may prefer a longer rise time.
Note: A prolonged rise time inhibits fast pressurization, therefore, rise time should not be set longer
than Ti Min or the patient's normal inspiratory time.

Leak management with VSync

Using ResMed's VSync algorithm, the AirCurve 10 device monitors and compensates for leak by
continuously and automatically adjusting the baseline flow. This enables reliable delivery of therapy
pressure while maintaining patient-device synchrony.

Comfort features

Ramp

Designed to make the beginning of treatment more comfortable, ramp is available in all modes.
In S, ST, T, PAC and iVAPS 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 iVAPS mode, Pressure Support is maintained at the minimum pressure support (Min PS).
In CPAP mode, the pressure increases from a low pressure (Start Pressure) to the prescribed
treatment pressure.
