Figure 1
Demonstration of pressure, flow, and electrical activity curves of the diaphragm. (A) Maximum electrical activity of the diaphragm, showing phasic activity of the diaphragm, and minimal electrical activity of the diaphragm, or tonic activity. (B) Proportional increase in airway pressure in response to the corresponding increase in electrical activity of the diaphragm. EAdi - electrical activity of the diaphragm; flow - flow; paw - airway pressure.

Increase in the positive inspiratory pressure and the electrical activity of the diaphragm according to the level of neurally adjusted ventilatory assist increases until the breaking point (1.5cmH2O/mcV) in premature infants. NAVA - neurally adjusted ventilatory assist.

(A) Lines marked in blue on the electrocardiographic tracing demonstrate adequate positioning of the catheter for measuring diaphragm electrical activity. (B) Simultaneous recording of electrical activity. (1) Schematic of the positioning of the catheter and its outputs for feeding and coupling with the neurally adjusted ventilation assist cable. (2) Probe in the esophagogastric position. (C) Neurally adjusted ventilation assist cable that attaches to the mechanical ventilator.
