Triggering and cycling
S, ST and iVAPS modes only
The device has adjustable trigger/cycle sensitivity to optimise the sensing level according to patient
conditions.
Under normal conditions, the device triggers (initiates IPAP) and cycles (terminates IPAP and
changes to EPAP) as it senses the change in patient flow. Patient breath detection is enhanced by
ResMed's VSync automatic leak management.
Note:
In PAC mode, only Triggering is available.
TiControl - Inspiratory time control
S, ST and iVAPS modes only
Unique to ResMed bilevel devices, TiControl
™
allows the clinician to set minimum and maximum
limits on the time the device spends in IPAP. The minimum and maximum time limits are set at
either side of the patient’s ideal spontaneous inspiratory time, providing a ’window of opportunity’
for the patient to spontaneously cycle to EPAP.
The minimum time limit is set via the Ti Min parameter and the maximum time limit is set via the Ti
Max parameter.
TiControl’s Ti Max and Ti Min parameters play a significant role in maximising synchronisation by
effectively intervening to limit or prolong the inspiratory time when required. This ensures
synchronisation, even in the presence of significant mouth and/or mask leak.
