Fig. 1From: Use of airway pressure-based indices to detect high and low inspiratory effort during pressure support ventilation: a diagnostic accuracy studyOffline analyses of inspiratory effort using the total respiratory muscle pressure–time product (A), the negative airway pressure generated during the first 100 ms (P0.1) and the maximal negative swing of airway pressure (∆Pocc) against an end-expiratory airway occlusion (B), and pressure muscle index (PMI) induced by an end-inspiratory airway occlusion (C).
