Alteration of end-expiratory lung volume ΔEELV (a), mean lung volume ΔMLV (b) and comparison in percentage air distribution between ventral and dorsal lung areas (c). BL = volume-controlled baseline ventilation, VCV = volume-controlled ventilation and FCV = flow-controlled ventilation. On each box, the central mark indicates the second quartile, the bottom and top edges indicate quartiles (25th percentile and 75th percentile). * = p ≤ 0.001 for FCV vs. VCV [linear mixed effect model analyses were used to check for differences between the ventilation phases using R based software (jamovi project 2018, version 0.9.2.3)]. The randomization had no significant effect on the measured difference in end-expiratory lung volume between the ventilation phases
