^aPatient ID in table 3 correlates to patient ID in table 2

^bPatients with no details were not requiring invasive mechanical ventilation at the time;

^cUnit of measurement is cmH2O

^§Patient intubated en route to hospital but extubated within a few hours of admission;

^±Patient not intubated until 72 hours of ARDS

Abbreviations: HFOV = high frequency oscillatory ventilation; ECLS = Extracorporeal Life Support; PIP = Peak inspiratory pressure; PEEP = Positive end expiratory pressure; MAP = Mean airway pressure; TV = Tidal Volume
