Fig. 2

Example of regional opening/closing pressures (a) and atelectrauma index curves (b) in two representative patients. Distribution of opening/closing pressure in two representative patients (a) and the corresponding representation of atelectrauma index (b). Red pixels: pixels with inspiratory regional LIP along the inspiratory limb of the PV curve and expiratory regional LIP along the expiratory limb of the PV curve, DZ = relative change of pixel impedance. Images of tidal change during the PV maneuver, pixels ventilated > 10% of the max pixel are displayed. AtI = atelectrauma index (percentage of opening/closing pixels on total ventilated pixels)
