Supports short-term 35% O2 to raise SaO2 after elective surgery; confirms benefit versus room air in RCT.
Does breathing 35% O2 improve oxygen arterial saturation compared to room air in patients after elective surgery?
Breathing 35% oxygen significantly improves arterial oxygen saturation compared to room air in the early postoperative period after elective surgery.
