Capacity	Inclusion criteria
Overall inclusion	Age: 18–65 paO₂/FiO₂ < 100 (pH < 7.25 for > 6 hours; paCO₂ > 60 mmHg or paO₂ < 50 mmHg) pH < 7.2 with plateau pressures > 30 cmH₂O Ventilator: < 10 days ventilator support Failed proning
< 50% capacity	Age: 18–65 paO₂/FiO₂ < 100 (pH < 7.25 for > 6 hours; paCO₂ > 60 mmHg or paO₂ < 50 mmHg) pH < 7.2 with plateau pressures > 30 cmH₂O Ventilator: < 10 days ventilator support Failed proning
50–80% capacity	Age: < 60 Ventilator: < 7 days ventilator support Peak pressures on ventilator < 40 cmH₂O Failed proning
