  1. Data are presented as percentages of N (%), medians (IQR) or means ± SD. Hypoxemia was defined as a drop of SpO2 ≤90% within five minutes after cessation of oxygen supply.
  2. Abbreviations: SpO2, peripheral oxygen saturation; PaO2, partial pressure of arterial oxygen; FiO2, fraction of inspired oxygen.
