Operations Ventilation Modes
5.5.8.1 Pressure Support in Synchronized Intermittent Mandatory
Ventilation (SIMV)
In SIMV-VC and SIMV-PC Ventilation modes, PS Ventilation can be turned on and off by changing
the PS setting to On and Off, respectively. When PS Ventilation is Off, the ΔP and Tslope settings
are disabled in SIMV-VC mode, and the ΔP setting is disabled in SIMV-PC mode.
5.5.8.2 Synchronized Intermittent Mandatory Ventilation–Volume
Control (SIMV-VC)

SIMV-VC means to deliver synchronized intermittent mandatory volume controlled ventilation to
the patient. In the SIMV-VC mode, the ventilator waits for patient’s next inspiration based on the
specified time interval. The sensitivity depends on Trigger. If Trigger is reached within the trigger
waiting time (called synchronous trigger window), the ventilator delivers volume controlled
ventilation synchronously with the preset tidal volume and inspiratory time. If the patient does
not inspire within the trigger window, the ventilator delivers volume controlled ventilation to the
patient at the end of trigger window. Spontaneous breathing outside trigger window can acquire
pressure support.
In VCV and SIMV-VC modes, when inspiration pressure reaches Plimit, the inspiration pressure is
held.
