Group mean values of measured variables during neurally adjusted ventilatory assist level titration. Leftmost panel: Mean and 95% confidence interval values (y-axis) for peak inspiratory change in esophageal pressure from onset of electrical activity of the diaphragm (ΔPes, open blue circles), applied positive end-expiratory pressure (PEEP, open green squares), peak airway pressure (Pawpk, green solid squares), peak inspiratory change in transpulmonary pressure from onset of electrical activity of the diaphragm (ΔPtp, blue solid circles) above PEEP, as the neurally adjusted ventilatory assist (NAVA) level was increased from 0 to 3.0 cmH2O/μV (x-axis). Next three panels to the right: Mean and 95% confidence interval values plotted for peak electrical activity of the diaphragm (EAdipk), inspiratory tidal volume (Vtinsp) for assisted (closed symbols) and non-assisted breaths (open symbols) and breathing frequency (Fb) during increasing NAVA levels.
