RECRUITMENT
Aerated lung volume (FRC + recruitment) at each PEEP level was calculated as the sum of FRC (After the study end, ventilation was resumed as clinically indicated by the attending physician.Of note, although physiologic measurements were derived from derecruitment PEEP trials, we refer to the terms “recruitment” and “recruitability” when describing our results. This approach is consistent with what previously done in similar investigations,
