SAPS 3 Simplified acute physiology score 3, Resp. Failure respiratory failure, MV Mechanical ventilation, PSV Pressure Support Ventilation level on the day of the study, PEEP positive end-expiratory pressure on the day of the study, FIO ₂ inspired fraction of oxygen, COPD Chronic Obstructive Pulmonary Disease. Duration of mechanical ventilation is shown in days before inclusion in the trial
