5.2.1. A/C V (Assist Control Ventilation)
In this mode the ventilator can deliver either volume ventilation
(VCV) if Tidal Volume (Vt) is selected (Figure 10.a) or pressure
ventilation (Figure 10.b) if Pressure Controlled Ventilation (PCV) is
selected. Choosing either mode will disable the other one which
will be displayed with (-) on the screen.
Volume control ventilation (VCV) with Tidal Volume and ventilation
Rate setting according to patient size is the default start up for this
mode (see Table-2 below).
During A/C V mode, the ventilator will deliver Controlled Mandatory
Ventilation (CMV) regardless of any patient’s eff ort if the trigger
(Trig.) is disabled (displayed with (-)).
The default trigger for A/C V is 3 L/min but can be adjusted up to
15 L/min.
If no inspiratory eff ort is detected during the trigger window, the
ventilator will initiate mandatory ventilation at the end of trigger
window. Should the patient demand more fl ow than set by user, he/
she can withdraw the excess from ambient.
