Regional tidal variation within 32 horizontal rows of the right and left halves of EIT image in each measurement phase a before neuromuscular blockade (baseline), b after neuromuscular blockade (NMB), c after tracheotomy (PDT) and d after a subsequent recruitment maneuver (RM). No significant changes in regional tidal variation were detected among the four time points of our standard PDT procedure (n = 29; RM ANOVA; p > 0.05)
