Prima 320 Advance 56 User Manual
6.4.8 Synchronised intermittent mandatory
ventilation - Pressure-regulated volume
controlled (SIMV-PRVC)
SIMV-PRVC delivers pressure controlled breathing to the
patient and the ventilator waits for patient’s next inspiration
based on the specified time interval.
Sensitivity depends on trigger level (F = 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 guaranteed ventilation - volume control 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 trigger window.
Spontaneous breathing outside of the trigger window can
acquire pressure support.
If trigger level is reached outside of the trigger window, the
ventilator delivers pressure-supported ventilation based on
the preset [Psupp].
