A Association between ΔR/I (difference of R/Isupine − R/Iprone) and the difference of the percentage of PEEP-induced recruitment between supine and prone position, as measured by CT scan. Patients were mainly distributed in two quadrants. In the left lower quadrant, pink dots represent the group of patients in which recruitability is higher in prone compared to supine position (negative ΔR/I). In these patients, PEEP-induced recruitment, as measured by CT scan, was also higher in prone than supine position. In the right upper quadrant, black dots represent the group of patients with a positive ΔR/I, indicating that PEEP-induced recruitability is lower in prone compared to supine position. B: Association between ΔR/I and PEEP-induced recruitment in prone position. The group of patients color-coded in panel A show in panel B lower recruitment induced by PEEP in prone position, suggesting that lung recruitment has already occurred due to the turn in prone position
