This study’s results differed from previous single center study (Girardis JAMA 2016) or meta analysis (Chu DK, Lancer 2018), which showed mortality benefit in patients with conservative oxygen (Girardis & Chu) and more ventilator-free days (Girardis).
Conclusion: Conservative oxygen did not significantly affect the ventilator free days of mechanically ventilated patients.
