10.7 PRVC
A
PRVC is a controlled mode of ventilation which
combines the advantages of volume controlled
and pressure controlled ventilation. The
system delivers the preset tidal volume with
the lowest possible pressure.
The flow during inspiration is decelerating. The
patient can trigger extra breaths.
The system can be configured to set Tidal
Volume or Minute Volume.
The time for inspiration and expiration is
configured by setting the I:E ratio or Ti
(inspiration time).
The following parameters are set:
1. Tidal Volume (ml) or Minute Volume (l/min)
2. Respiratory Rate (b/min)
3. PEEP (cmH

4. I:E ratio / Insp. time
