Figure 5

Comparison of global values for respiratory system compliance. (A) Correlation between the global respiratory system compliance (Crs), determined with electrical impedance tomography during assisted spontaneous breathing with the (PEEP) wave maneuver (Crs(PEEP wave)), and quasi-static Crs, determined in the passive patient with a low-flow pressure-volume loop (Crs(low-flow). (B) Bland-Altman method comparison between Crs(PEEP wave) and Crs(low-flow). The dashed line indicates the bias (+6.8 ml/cmH2O), and the dotted lines indicate the 95% limits of agreement (−20.8 to +34.5 ml/cmH2O). (C) Correlation between Crs(PEEP wave) and Crs, determined during volume-controlled ventilation (Crs(CMV)). (D) Bland-Altman method comparison between Crs(PEEP wave) and Crs(CMV). The dashed line indicates the bias (+17.1 ml/cmH2O), and the dotted lines indicate the 95% limits of agreement (−13 to +47 ml/cmH2O).
