Figure 5From: Computed tomography assessment of exogenous surfactant-induced lung reaeration in patients with acute lung injuryIndividual and mean changes in volume of gas and tissue in poorly/nonaerated lung regions (upper part of the figure) and normally aerated lung regions (lower part of the figure). Volume changes were measured on computed tomography scans acquired at baseline and seven days in patients who received either usual care (control, open circles) or usual care plus intratracheal porcine-derived surfactant (HL-10, closed circles). In the surfactant group, each patient is identified by a specific symbol.Back to article page
