breaths will be pressure controlled with a guaranteed volume at the
inspiratory limb.
A portion of the exhalation phase is defined as the trigger window. If
a spontaneous breath is detected in this window, a new mandatory
PCV-VG breath is initiated. If a spontaneous breath is detected
outside of this window, support for this breath is provided according
to the set pressure support. The remainder of the trigger window is
added to the next non-triggering phase.
The inspiratory phase of supported breaths will end if the set End of
Breath is reached, if the airway pressure exceeds (PEEP + Psupport
+ 3 cmH2O). Supportive breaths have a maximum inspiratory time of
4 seconds.
