Fig. 2
Evolution of tidal Volume (Vt) and Fraction of Delivered Oxygen (FD02) during the VV-ECMO course. Illustrates the significant decrease in Vt promptly after ECMO initiation, followed by a gradual but persistent improvement over weeks, accompanied by a decline in FDO2 requirement. Abbreviations: Vt: Tidal Volume, FD02: Fraction of Delivered Oxygen in ECMO sweep gas. The blue curves represent the mean Vt over time (left y-axis), while the red curve represents the mean FDO2 over time (right y-axis)
