What researchers measure

Primary outcomes

  1. PaO2/FiO2

    Arterial partial pressure of oxygen / Fraction of inspired oxygen

    Time frame: Within 2 hours before pronation and 2 hours before supination

Secondary outcomes

  1. Alveolo-arterial oxygen gradient change

    Time frame: Within 2 hours before pronation and 2 hours before supination

  2. Ventilatory Ratio

    Time frame: Within 2 hours before pronation and 2 hours before supination

  3. Mortality or Extracorporeal membrane oxygenation (ECMO) support

    Time frame: Once between ICU admission and extubation
