Potential for lung recruitment and changes in respiratory system compliance induced by PEEP in 30 ARDS patients. Re-analysis of data from [10]. Lung recruitability (assessed as absolute recruited volume normalized to the change in PEEP—left, and the recruitment-to-inflation ratio—right) in patients who showed increased, unchanged (defined as a clinically relevant modification of < 5 ml/cmH2O) or diminished respiratory system compliance as a response to 10-cmH2O PEEP increase. Changes in respiratory system compliance are ineffective measure of the recruitment induced by PEEP. Data from individual patients, medians and interquartile ranges are displayed. The dotted horizontal lines represent the mean values of recruitment and recruitment-to-inflation ratio in the study cohort. Data were analyzed with the Kruskal Wallis test.
