The feasibility of NAVA use has been described in neonatal and pediatric patients. Several studies cite a decrease in peak inspiratory pressures, improved synchrony in triggering, and more appropriate termination of positive pressure support. Some studies have reported lower work of breathing, PaO2/FiO2 ratios (partial pressure of oxygen/ fractional inspired oxygen)and MAP. In addition, NAVA has been used for patients who "fight the ventilator," and the synchrony improves the ability to wean.
