6.6.7.1 Synchronized Intermittent Mandatory Ventilation–Volume Control
(SIMV-VC)
Figure 6-6 Synchronized Intermittent Mandatory Ventilation–Volume Control (SIMV-VC) Tab
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.
6.6.7.2 Synchronized Intermittent Mandatory Ventilation–Pressure Control
(SIMV-PC)
Figure 6-7 Synchronized Intermittent Mandatory Ventilation–Pressure Control (SIMV-PC) Tab
SIMV-PC means to deliver synchronized intermittent mandatory pressure controlled ventilation to the
patient. In the SIMV-PC 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 pressure controlled ventilation
synchronously with the preset tidal volume and inspiratory time. If the patient does not inspire within
the trigger window, the ventilator delivers pressure controlled ventilation to the patient at the end of
trigger window. Spontaneous breathing outside trigger window can acquire pressure support.
