Evolution of global shunt-EIT (%), dead space-EIT (%), and V/Q matching (%) at T0, T1, T2 and T3 (A). Evolution of V/Q matching (%) in ventral and dorsal region at T0, T1, T2 and T3 (B). Subgroup analysis of V/Q matching (%), shunt-EIT (%), and dead space-EIT (%) evolution at T0, T1, T2, and T3 (C, D). Patients were divided into two subgroups based on the severity of ARDS: moderate ARDS with seven patients (C) and severe ARDS with five patients (D). Better dorsal ventilation (%) was significantly correlated with higher PaO2/FiO2 (E) and lower PaCO2 (F). V/Q, ventilation/perfusion; EIT, Electrical impedance tomography; ARDS, acute respiratory syndrome. T0: shortly after APRV; T1, T2, and T3: 6 h, 12 h, and 24 h after APRV application. *p < 0.05
