Figure 2From: Comparison of quantitative computed tomography analysis and single-indicator thermodilution to measure pulmonary edema in patients with acute respiratory distress syndrome Distribution of the tissue volume compartments for the whole lung in each patient. Lung compartments were classified according to CT values as hyperinflated (CT values less than -900 HU), normally aerated (between -500 and -900 HU), poorly aerated (between -100 and -500 HU), and nonaerated (between -100 and + 100 HU).Back to article page
