Dynamic respiratory system compliance, alveolar overdistension, and alveolar collapse for the whole population from admission to beyond a week after in ICU survivors and ICU non-survivors. EIT population curves that show mean (solid lines), dynamic compliance (green), overdistension (blue), and collapse (yellow) with 95% confidence intervals (dashed lines) from PEEP steps 28 to 8 cmH₂O for ICU non-survivors over time for the first 3 days (A), for day 4, 5 and 6 (B) and for day 7 and above (C); and for ICU survivors over time for the first 3 days (D), for day 4, 5 and 6 (E) and for day 7 and above (F).
