Airway pressure-time curve profile (stress index) detects tidal recruitment/hyperinflation in experimental acute lung injury. Shape of the Paw-t curve detects tidal recruitment and tidal hyperinflation. Pulmonary computed tomography was obtained during end-expiratory and end-inspiratory occlusions. Tidal recruitment was quantified as nonaerated (between −100 and +100 Hounsfield units) lung area at end-expiration minus end-inspiration.
