Oxygen physiology and pulse oximetry lag podcast


This podcast, from the Scott Weingart’s superb emcrit.org┬ásite, discusses the lag between oxygen delivery commencing following RSI and the rise in saturations on the patient monitor. It is directly relevant to the prehospital setting, given that a colder environment and a shocked/underresuscitated patient results in a longer pulse oximetry lag. The discussion also makes note of several cases where a (probably) successfully placed ETT was removed in the prehospital setting due to pulse oximetry lag.
