Episode 6: Oxygenate Differently

The venerable non-rebreather mask has long been considered the gold standard for high flow oxygen delivery. But is that reputation deserved? We’ll discuss the science and benefits of the lowly nasal cannula and how it can help us oxygenate even apneic patients. Next time you see someone putting on a nasal cannula to a patient in respiratory arrest, they might not be crazy — they may just be practicing NODESAT and apneic oxygenation. We’ll also cover other tips and tricks, such as positioning, use of airway adjuncts, and the “Two Thumbs Down” mask seal technique.

Why should we do 15-liters by nasal cannula?

Evidence shows that it maintains or improves oxygen saturation, even in patients who are entirely apneic.

How quickly do patients desaturate without supplemental oxygen during intubation? Too fast.
