Fig. 5From: Prone positioning monitored by electrical impedance tomography in patients with severe acute respiratory distress syndrome on veno-venous ECMOElectrical impedance tomography (EIT)-estimated optimal positive end-expiratory pressure (PEEP) before and at the end of a prone positioning (PP) session, for patients with an increase of the static compliance by ≥ 3 mL/cmH2O (PCG−) (red) and patients with static compliance < 3 mL/cmH2O, respectively (PCG−) (green). Whiskers plots report the median = central horizontal line; interquartile range = bottom and top box limits and 90% percentile = T bars, • = outliers. *P < 0.05 vs. baselineBack to article page
