Randomized Controlled TrialThe Oxygen Reserve Index as a determinant of the necessary amount of postoperative supplemental oxygen.
Although blood gas analysis (BGA) is important for supplemental oxygen titration, it is invasive, intermittent, costly, and burdensome for staff. We assessed whether the Oxygen Reserve Index (ORi™), a novel pulse oximeter-based index that reflects the partial pressure of oxygen (PaO
2 ), could determine the amount of postoperative supplemental oxygen. We also evaluated the extent of hyperoxia and hypoxia. ⋯ Based on our results, ORi might be useful to titrate postoperative oxygen supplementation.
