Data reported as Number (Percentage) or Median [Interquartile Range]; Differences between groups were assessed with a Mann-Whitney U test or Fisher’s Exact test depending on variable type. ECMO: Extra-Corporeal Membrane Oxygenation; ICU: Intensive Care Unit

^§Barotrauma defined as spontaneous pneumothorax and/or pneumomediastinum during mechanical ventilation

^¶Extubation and immediate re-intubation due to life-threatening airway occlusion.
