Podcast #260: Preoxygenation

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.
