Intraoperative mild hyperoxia may be associated with improved survival after off-pump coronary artery bypass grafting: a retrospective observational study

ConclusionsMaintaining intraoperative PaO2 at 150 –250 mmHg was associated with a lower risk of mortality after OPCAB than PaO2 at< 150 mmHg and at> 250 mmHg. Future randomised trials are required to confirm if mildly increasing arterial oxygen tension during OPCAB to 150 –250 mmHg improves postoperative outcomes.
