Why the study?
Postoperative supplemental oxygen is routinely given, but hyperoxemia carries potential respiratory and cardiovascular harms, and recommendations for routine high-dose oxygen have been challenged.
Does a conservative approach to oxygen therapy improve outcomes compared to routine high-dose supplemental oxygen in postoperative surgical patients?
Does a conservative approach to oxygen therapy improve outcomes compared to routine high-dose supplemental oxygen in postoperative surgical patients?
Routine high-dose postoperative oxygen administration may cause hyperoxemia-related harm, suggesting a conservative, titrated approach is preferable.
