Oxygen physiology and pulse oximetry lag podcast

corpuls

This podcast, from the Scott Weingart’s superb emcrit.org site, 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.
