Trigger and cycle
Devices with VAuto, S and STmodes have adjustable trigger/cycle sensitivity to optimize changes in patient sleep patterns. Under normal conditions, the device triggers (initiates IPAP) and cycles (terminates IPAP and changes to EPAP) as it monitors and corrects patient respiration. ResMed's VSync automatic leak management recognizes and corrects patient breath patterns.
Note
Trigger and cycle parameters are not available in all regions.
