5.8.8 P-SIMV

Pressure-targeted synchronised intermittent mandatory
ventilation.
•
The system displays all PRP related to the operative
mode set.
P-SIMV
is a synchronised intermittent mandatory ventilation, during which the Unit generates a
certain number of breaths per minute (RRsimv) at a pre-set inspiratory pressure (Pinsp) providing
pressure support (PS) during the spontaneous phase.
SIMV allows the patient to breath spontaneously, between the forced breaths, with a pre-set positive
pressure support (PS) if the patient's breath is strong enough to enable the flow trigger (Tr. I - this
parameter can't be set to OFF).
The spontaneous phase is characterised by the set inspiration time (Ti) that once the pressure
support value (PS) set by the User is reached, leaves its place to the expiration phase (Tr. E).
Therefore, in SIMV mode, the Unit can provide a combination of spontaneous and controlled
breathing. SIMV mode is frequently used as a weaning ventilation mode from a fully controlled
ventilation (completely depending on the unit) to an assisted ventilation mode.
