Fig. 3From: Respiratory drive heterogeneity associated with systemic inflammation and vascular permeability in acute respiratory distress syndromeRespiratory drive and survival. Kaplan–Meier plots. Patients were classified as having low drive if PES0.1 was less than 0.5 cm H2O, moderate drive if between 0.5–2.9 cm H2O, and high drive if 3.0 cm H2O or higher. PES0.1 refers to the change in esophageal pressure, a surrogate of pleural pressure, during the first 0.1 s (100 ms) of patient inspiratory effortBack to article page
