Fig. 1

Regional distribution of ventilation (\(\dot{V}\), blue bars) and perfusion (\(\dot{Q}\), red bars) across areas with different ranges of \({{\dot{V}} \mathord{\left/ {\vphantom {{\dot{V}} {\dot{Q}}}} \right. \kern-\nulldelimiterspace} {\dot{Q}}}\) ratio at Positive End Expiratory Pressure (PEEP) 5 and 15 cmH2O. Histograms represent mean values (± SEM). ND: non-dependent part of the lungs, M: middle part of the lungs, D: dependent part of the lungs. *p < 0.05, †p < 0.01, ‡p < 0.001 by paired t-test
