Fig. 1From: The global inhomogeneity index assessed by electrical impedance tomography overestimates PEEP requirement in patients with ARDS: an observational studyChanges in Cdyn (a), GI (b) and percentages of ODCL (c) in patients with ARDS (square, black) and control patients (circle, red) during an incremental and decremental PEEP trial. (p < 0.0001, p = 0.541, p = 0.913 respectively) ODCL, balance between alveolar overdistension and collapse; GI, global inhomogeneity index; Cdyn, dynamic respiratory system complianceBack to article page
