Figure 2

A typical curve of (right) GI index of one patient (left) during a standardized PEEP trial. The x axis displays the number of breathing cycles, counted once the maneuver started. A minimum value of the global inhomogeneity (GI) index indicated the optimal positive end-expiratory pressure (PEEP) with respect to ventilation homogeneity. Paw = pressure at airway opening.
