A “take home” from ACEP by Dr. Susie Peterson
In the wisdom of Scott Weingart…
· Keep the nasal cannula on your patient during intubation and you just might buy yourself some extra time to get the tube in…
· Even during apnea oxygen continues to be absorbed from the alveoli across the pulmonary vasculature
o If you continue to supply continuous oxygen (via nasal cannula) oxygen will flow down the gradient from the nasopharynx to the oxygen depleted alveoli.
