[quote=Anonymous]I remember seeing the term "happy hypoxics" or something like that last spring, about people with Covid whose O2 levels were very low. Just looked it up and there has been investigation into the reasons such patients don't show outward signs of distress, which can be complex. In some cases, apparently, things like intubation are actually contraindicated despite the low O2 levels. Problem with the meter itself is one possibility but only one. Some of those people they were referring to had blood saturation down to the 50s! But also oximeter readings are most accurate in the high ranges, when you fall below 90 they are far less accurate according to what I read. People also need to be aware that oximeters may OVER estimate the O2 saturation in people with dark skin (pigmentation affecting the readings). [/quote]
