Backup Rate; Cpap Mode; Leak Management With Vsync; Comfort Features - ResMed Defy Mini User Manual

Backup rate

The AirCurve 10 CS PaceWave device uses breath phase mapping to provide a timed backup rate
that is synchronised with the patient's own breathing. When the patient deviates from the
ventilatory target, the CS PaceWave device aims to stabilise the patient by adjusting Pressure
Support. If necessary, it will adjust the timed backup rate from one that matches the patient's own
recent rate towards the built-in default 15 BPM backup rate.

CPAP mode

In CPAP mode, a fixed pressure is delivered.

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.
Note: Ramp is not recommended for patients exhibiting CSR during sleep onset.
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.
