This figure represents the variation of aeration in the dependent dorsal lung (% dependent dorsal lung region) in supine between 2 prone position (PP) sessions (around 8 h of supine position [SP] each day). PP was followed by a significant de-recruitment within 2 h in SP. One-way analysis of variance used for repeated paired measurements with multiple comparison. VT = tidal volume.

Fig. 1.
This figure represents the lost of aeration of dependent dorsal lung in supine between 2 prone position (PP) sessions (% dependent dorsal lung region T1-T2) the day of the first PP, the day of the highest de-recruitment, and the day of the last PP session. The red lines represent the median. At the bottom of the figure are the numbers of days between PP sessions, median [interquartile range]. VT = tidal volume; PPfirst = first prone position session; PPmax = day of the highest de-recruitment; PPlast = last PP session.
