Author: Dr. David Rosenberg

Educational Pearls:

  • Preoxygenation provides plenty of oxygen to the patient so that he/she does not desaturate during RSI.
  • Even if the patient is at 100% on spO2 monitor, preoxygenation is necessary for continued saturation of hemoglobin and transport of oxygen to the rest of the body – respiration continues even though breathing stops.
  • Air is approximately 20% oxygen – which means only 20% of the lung volume is oxygen.
  • 5 minutes on a non-rebreather mask prior to RSI will get 90% of the lung volume to be oxygen – allowing for respiration to continue as normal during RSI even if it takes time.
