Respiratory system mechanics associated with the percentage of collapse and hyperdistention at different levels of PEEP. In panels A, D, and G, data were obtained by electrical impedance tomography, where ● is the respiratory system compliance; Δ is the percentage of collapse and □ is the percentage of overdistension. Panels B, C, E, F, H, and I show the percentage change in driving pressure obtained by a mechanical ventilator for a representative patient (B, E, H) and all patients (C, F, I). Panels A–C correspond to the category of patients with J-shaped curves; panels D–F correspond to the category of patients with U-shaped curves, and panels G–I correspond to the category of patients with inverted J-shaped curves
