I tend to SHOs in A&E the same thing. They invariably come from housejobs thinking that oxygen is the most potent poison known to man and never give anyone more than 24%. I tell them that hypoxia kills in minutes, CO2 retention takes longer, so give high FiO2 to anyone sick, but be prepared to do arterial gases EARLY in anyone going off and reduce O2 later if needed. ps: The pulse oximeter is a dangerous piece of kit in anyone breathing hi flow O2: it gives you a false sense of security about their sats, but tells you nothing about their CO2 levels. Don't get me started on that one! Dr G Ray Staff Grade A&E Sussex Reply to [log in to unmask] %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
