I'm an ICU RN and my hospital policy just changed
. When monitoring oxygen sats we can't put finger sensors on the forehead anymore. The reading is inaccurate. I get that it is wrong, test it if you don't believe me. It shows 100% when it should say 80%. I just want to know the reason why it doesn't work. If you have any idea please let me know. No one can tell me
. They can only tell me that it doesn't work. I've tried researching it, but can't find it anywhere :trout: .
