Regional alveolar hyperdistension and collapse distribution in all study phases. Alveolar hyperdistension and collapse was significantly reduced in dependent lung layers and significantly increased in non-dependent lung layers compared with PEEPARDSnet in both PEEPEIT and PEEPEIT+2 phases. Furthermore, in middle-ventral lung layers alveolar hyperdistension and collapse was significantly higher in PEEPEIT+2 phase compared with PEEPARDSnet, but did not change in PEEPEIT step. *p < 0.05 compared with PEEPARDSnet phase
