Fig. 6From: Information conveyed by electrical diaphragmatic activity during unstressed, stressed and assisted spontaneous breathing: a physiological studyEffect of stressed assisted ventilation on MV (a), RR (b), VT (c) and PTPeso/min (d). MV minute ventilation, RR respiratory rate, VT tidal volume, PTPeso/min esophageal pressure–time product by minute. SBr spontaneous non-assisted breathing in the presence of the resistance, PSV pressure support ventilation. NAVA neurally adjusted ventilatory assist. The data of all the participants are displayed in the figure. Patients for whom all the conditions were available are represented as white circles. Patients for whom one or more conditions could not be recorded are represented as gray triangles. Only the patients represented as white circles were considered for median calculations and Friedman analysesBack to article page
