II. Tidal volume
III. Inspiratory time
IV. Inspiratory flow

Question

Quizplus · Accepted Answer

Volume guarantee (VG) is another form of adaptive-control ventilation that is used in one type of neonatal ventilator. The operator sets a tidal volume, inspiratory time, and flow rate. This mode can also be applied to pressure support ventilation. The ventilator incorporates a proximal flow sensor at the patient airway. The microprocessor assesses an eight-breath historical average of expired tidal volume and will increase pressure on the basis of these measurements up to the pressure limit to deliver the target volume.
