Apneic oxygenation is the delivery of high-flow oxygen by nasal cannula during endotracheal intubation. Two separate meta-analyses provide pooled results from trials of apneic oxygenation.
The first meta-analysis included 8 studies and 1953 patients in critical care settings. It found that the risk for “clinically significant hypoxemia” (reduction of oxygen saturation to <90%–93%) was 28% in the usual care group and 19% in the apneic oxygenation group — a reduction of 30% — without any heterogeneity in outcome across studies.
The second meta-analysis included 6 studies and 1822 patients in prehospital and emergency department settings. It found that the risk for “critical desaturation” (reduction of oxygen saturation to <80%) was halved (rela…
