Operations Set Ventilation
SIMV-VG means to deliver synchronized intermittent mandatory pressure control volume guarantee
ventilation to the patient. In the SIMV-VG mode, the ventilator waits for patient’s next inspiration
based on the specified time interval. The sensitivity depends on F-Trig (or P-Trig). If F-Trig (or P-Trig) is
reached within the trigger waiting time (called synchronous trigger window), the ventilator delivers
pressure controlled volume guarantee 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 volume guarantee ventilation to the patient at the end of trigger window.
Spontaneous breathing outside trigger window can acquire pressure support.
