Intraoperative respiratory parameters in a subgroup of subjects with end-inspiratory Pes measurements. (a) Driving pressure. (b) Transpulmonary driving pressure. (c) End-inspiratory transpulmonary driving pressure. (d) End-expiratory transpulmonary driving pressure. (e) Respiratory system elastance (ERS). (f) Lung elastance (EL). (g) Correlation between driving pressure and transpulmonary driving pressure. (h) Correlation between respiratory system elastance (Ers) and lung elastance (EL). (Boxplots represent median (Q1, Q3); error bars represent minimum and maximum values; full dots identify outlier values. Results of post hoc comparisons are shown if significant differences observed between the three groups: for post hoc comparisons, P≤0.01667 (=0.05/3) statistically significant. However, we also indicate for completeness all two-group comparisons where 0.01667<P<0.05 as these would be considered significant if we had not adjusted for multiple comparisons. ∗P-value 0.01667<P<0.05 compared with control; ˆP-value 0.01667<P<0.05 PEEPPtp_eevs PEEPmaxCrs ∗∗P≤0.01667 compared with control; ˆˆP≤0.01667 PEEPPtp_eevs PEEPmaxCrs.).
