7.4.6 VC/VAC BABY

The VC/VAC BABY is a volume controlled ventilation (Vte), synchronized with the
patient breathing acts if the inspiratory trigger is activated (Trig. I).
Being totally carried out by the equipment, this type of ventilation is used when the
patient is unable to breathe autonomously, or to ensure an effective pre-set tidal
volume, it is necessary to ventilate the patient in a completely mechanic mode.
The inspired tidal volume (Vte) is pre-set and is supplied in a pre-fixed time (RR and
I/E) and it determines the characteristics and the width of the necessary pressure to
reach the preset quantity of mixture to be delivered. A tended inspiratory act of the
patient is detected by the system (Trig I) which automatically provides to send to the
airways a gas flow at a preset volume (Vte).
To combine the assisted modality to the controlled one, it is necessary to adjust the
trigger sensitivity (Trig. I) at the appropriate value to the patient. If the patient, during
expiratory phase, makes a spontaneous breathing able to activate the trigger, the
ventilator synchronizes the breathing activity with such spontaneous act,
recalculating the times of the I:E ratio such event of synchronism, showing them on
ventilator display.
MORPHEUS
In this operative mode specifically for neonatal patient, respect to
the previous VAC, it has been introduced a parameter identifying
the max pressure limit which can be reached during ventilation.
