1. Pressure, flow, volume, and electrical activity of the diaphragm (EAdi) waveforms from a patient on pressure support ventilation, and the presumed pressure curve (grey) if the patient was on neurally adjusted ventilatory assist (NAVA), with a preset NAVA level not shown.

Breath 3 demonstrates expiratory timing asynchrony: there is continued mechanical inflation after the start of the neural expiration, causing a delay between the neural expiration and the mechanical deflation.
