Figure 4

Scatterplots of relative ZV and ZQ within ROI 1 to 4 for the left lung at baseline and following balloon inflation in relation to the relative ZV/ZQ ratio. ZV = ventilation-induced change in thoracic impedance; open circle. ZQ = perfusion-induced change in thoracic impedance; solid stars. Values presented as a proportion of global ZV and ZQ. Region of interest (ROI) 1 = ventral; ROI 2 = mid-ventral; ROI 3 = mid-dorsal; ROI 4 = dorsal. Binfl = balloon inflation; BL = baseline.
