Work of Breathing During Non-invasive Ventilation in Premature Neonates

Neurally adjusted ventilatory assist (NAVA) is a mode of ventilation that uses a functional naso/orogastric tube with embedded electrodes which detect diaphragmatic contractions (called the Edi signal). NAVA uses this Edi signal to synchronize ventilator support to the patient's own respiratory efforts and to support these efforts as needed.

"Nasal intermittent positive pressure ventilation (NIPPV) or noninvasive pressure control ventilation (NIV PC) is a mode of ventilation delivering unsynchronized puffs of air or breaths to a baby through nasal cannulae."
