Volume targeted controlled ventilation synchronised
with the patient if the inspiratory trigger is active.

operating mode.
VC/VAC is a volume-targeted controlled ventilation (Vti), synchronised with the patient's
breaths if the inspiratory trigger (Tr. I) is active.
In this type of ventilation the work of breathing is fully assumed by the lung ventilator, and
therefore it is used when the patient is unable to breath on his own, or in order to assure
an efficient pre-set current volume and therefore the mechanical ventilation must fully
replace the spontaneous breathing.
The inspired volume (Vti) is pre-set and generated in a pre-set time (RR and I:E) and
determines the characteristics and the pressure range necessary to reach the pre-set
amount of gas mixture that must be provided.
The patient's breathing attempt is detected by the system (Tr. I) and it automatically sends
inside the airway a gas flow at a pre-set volume (Vti).
