PSV Rise
The PSV Rise setting sets the slope of the pressure rise during a pressure-supported breath.
It is a relative control with a range from fast at a setting of 1 to slow at a setting of 9.
PSV Cycle
The PSV Cycle setting sets the percentage of peak inspiratory flow that terminates
the inspiratory phase of a PSV breath.
PSV Tmax
The PSV Tmax setting controls the maximum inspiratory time of a pressure-supported
breath.
Note: PSV Rise, PSV Cycle and PSV Tmax are active even if the PSV level is zero.
Volume Limit
The Vol Lim setting sets the volume limit for a pressure limited breath. When the volume
delivered to the patient meets or exceeds the pre-set volume limit, the inspiratory phase
of the breath terminates.
