Podcast #260: Preoxygenation
Show: Emergency Medical Minute
Author: David Rosenberg, M.D.
Educational Pearls
- Preoxygenation is done before rapid sequence intubation, and should be done even if SaO2 is at 100%.
- Preoxygenation is done to fill the lungs with oxygen rather than ambient air, which is only 20% O2. While the patient is paralyzed, the O2-filled lungs will continue to oxygenate venous blood, buying you more time for intubation.
- BiPAP is an effective tool for pre-oxygenation.
