Figure 6a. (a) Thin-section CT scan obtained at the baseline (time point 1) shows normal lung parenchyma. (b) Thin-section CT scan obtained when the effective pulmonary capillary pressure equaled the critical pulmonary capillary pressure (time point 3) shows diffuse ground-glass opacification. (c) Thin-section CT scan obtained 90 minutes after the effective pulmonary capillary pressure became higher than the critical pulmonary capillary pressure (time point 8) by 10 mm Hg shows diffuse ground-glass opacification and consolidations. (d) Thin-section CT scan obtained 60 minutes after the return of the left atrial pressure to the baseline value (time point 11) shows the remaining ground-glass opacification and consolidations.
