6.4.6 Synchronized intermittent mandatory ventilation -
Volume control (SIMV-V)
SIMV-V
SIMV-V delivers volume controlled breathing to the patient by
phase at the preset intermission.
In SIMV-V mode, the ventilator waits for the patient’s next
inspiration based on the specified time interval.
Sensitivity is dependent on Trigger level (Fsens = Flow trigger
sensitivity; Psens = Pressure trigger sensitivity; Esens =
Expiratory trigger sensitivity).
If the Trigger Level is reached within the trigger waiting time
(synchronous Trigger Window), the ventilator delivers volume
controlled breathing synchronously with the preset tidal
volume and inspiratory time.
If the patient does not inspire within the Trigger Window, the
ventilator delivers volume controlled breathing to the patient
at the end of Trigger Window.
Spontaneous breathing outside of the Trigger Window can
acquire pressure support.
