Prima 320 Advance 55 User Manual
6.4.7 Synchronized intermittent mandatory
ventilation - Pressure control (SIMV-P)
SIMV-P delivers pressure controlled breathing to the patient
by phase at the preset intermission.
In SIMV-P mode, the ventilator waits for the patient’s next
inspiration, based on the specified time interval.
Sensitivity depends on the 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 (called synchronous Trigger
Window), the ventilator delivers pressure controlled breathing
synchronously with the preset tidal volume and inspiratory
time.
If the patient does not inspire within the Trigger Window, the
ventilator delivers pressure controlled breathing to the patient
at the end of the Trigger Window.
Spontaneous breathing outside of the Trigger Window can
acquire pressure support.
If the Trigger Level is reached outside of the Trigger Window,
the ventilator delivers pressure-supported ventilation based
on the preset [Psupp].
