Example ventilator screen during nasal neurally adjusted ventilatory assist in a premature neonate (23 weeks gestational age, 560 g) with respiratory distress syndrome. The yellow, green, blue, and gray lines represent airway pressure, flow, volume, and electrical activity of the diaphragm (Edi) signal, respectively. The inspiratory pressure, trigger, and cycle is proportional to the Edi, and is captured with every spontaneous effort made by the patient.
