Apneic Oxygenation (ApOx)

R.E.B.E.L.EM - Jul 17, 2017
Apneic oxygenation (ApOx) is the passive flow of oxygen into the alveoli during apnea. This passive movement occurs due to the differential rate between alveolar oxygen absorption and carbon dioxide excretion producing a mass flow of gas from the upper respiratory tract into the lungs. Another important component of this maneuver is maintaining a patent airway so that supplemental oxygen administered through the nares is able to be delivered to the alveoli. This practice has been a game changer in emergency airway management for many providers. However, there are still some naysayers that believe in the sickest patients ApOx may not be so beneficial. This post is a review of two recent systematic reviews/meta-analyses published in the critical care and ED/retrieval settings on the use of ApOx..."
