Figure 1.
Daily measurements of the recruitment-to-inflation (R/I) ratio for each patient during the observation days. Each patient is indicated by a distinct color. (A) Five patients who did not receive prone positioning. Each triangle denotes a measurement in the supine position. (B) Seven patients who received at least one session of prone positioning. Each upside-down triangle denotes a measurement in the prone position. Notice that each session of prone positioning was maintained for 24 hours. The dashed line represents the cutoff of the R/I ratio for defining lung recruitability (R/I ratio ≥ 0.5 suggests highly recruitable).
