TV/VT ratio at different layers. Interrelation of global TV/VT ratio (black) and amount of negative impedances (grey) (a). Percentage decrease of TV/VT ratio (relative) deeming L1 as baseline (b). Regional TV/VT ratio (c, d) at different layers from cranial (L1) to caudal (L7). c Non-dependent/ventral. d Dependent/dorsal. Data are mean ± standard deviation. Kruskal-Wallis test with Dunn’s post hoc testing for pairwise multiple comparison. Significance compared with L1: *P < 0.05, **P < 0.01, ***P < 0.001. AU arbitrary units, L layer, TV/VT tidal impedance variation/tidal volume ratio
