Tidal volume (Vt) evolution in four patients treated with a second course of steroids. 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). Arrows represent the start of the second course of steroids. Abbreviations: Vt: Tidal Volume. FD02: Fraction of Delivered Oxygen in ECMO sweep gas
