PRVC-SIMV (Pressure Regulated Volume Synchronized Intermittent Mandatory
Ventilation)
Mandatory breaths in this mode are similar to PRVC-CMV mode. The ventilator delivers
breaths during Ti with pressure values that vary in each inspiration to achieve the target tidal
volume. The pressure values will not vary more than 3 cmH2O per breath. Only difference of
this mode with PRVC-CMV is that the ventilator could deliver spontaneous breaths which
are pressure supported.
Excessive increase of pressure or deliverd volume could cause terminating the inhalation. In
this situation, applied Ti may shorter than set Ti (see the alarms chapter).
Note:
When changing the Rate and Ti parameters, the values of Te and I: E are displayed on the
parameter setting menue.
Note:
During inhalation, if the airway pressure for any reason (such as the patient's cough) exceeds
the value specified for it, the exhalation valve opens and prevents further increase in pressure.
The below parameters could be set in this mode:
