Change in pulmonary electrical bioimpedance at distinct time points during the bronchoalveolar lavage procedure. The sums of all image pixel values of relative impedance changes (rel. ΔZ) in arbitrary units (AU) are given after the disconnection of the endotracheal tube from the ventilator before the lavage fluid instillation (t1), after the fluid instillation (t2) and after the fluid suction before the resumption of ventilation (t3), in each case compared to baseline before the disconnection to ambient pressure. The data originate from lavages performed first in supine (left), then prone (middle) and final supine (right) positions (supine I, prone and supine II, respectively). The numbers of analysed bronchoalveolar lavages in each posture are given at the top of each diagram. p values given in the diagrams highlight the highly significant effect of the time point. The significance of differences between the individual time points was obtained from post analyses at **p < 0.01 and ***p < 0.001. Significantly different values from the supine I position at corresponding time points are given as ††p < 0.01 and †††p < 0.001 and from supine II position as ‡‡p < 0.01
