2.8.4 PSV mode
PSV (Pressure Support Ventilation), in the PSV mode, when the patient is activated
spontaneously, the ventilator will support the patient’s inspiration with the pre-set stable
pressure, the flow curve is in downward trend. The end of the patient’s inspiration can be
changed by adjusting the sensitivity.
The PSV mode is combined with the SIMV mode.
In the PSV mode, the following parameters need to be set:

2.8.5 SIMV mode
SIMV (Synchronized Intermittent Mandatory Ventilation). In the SIMV mode, the
independent breathing frequency and the tidal volume (or inspiratory pressure) is
controlled by the patient, and a synchronous control is active at a certain interval of time. If
the trigger level is met in the waiting trigger window, the ventilator will provide a
synchronized volume (pressure or pressure regulated volume control) control ventilation
for the patient. If the trigger level is not achieved in the trigger window, at the end of the
trigger window, the ventilator will give a volume (pressure or pressure regulated volume
control) control ventilation.
The SIMV mode includes three modes: SIMV+VCV, SIMV+PCV and SIMV+PRVC mode,
