The Effects of Oxygen on Pneumonia

I'd like to ask about the oxygen where if you have someone that has a range of 80 to 90 or 85 to 95 that's coming in with a pneumonia. Maybe be tolerant of a little bit lower given the pneumonia, but can you talk about what the oxygen goal is. And one thing that I think is really helpful to conceptualize at least for me is what happens if I don't do thatWhat happens if I see 80. I freak out we put them on or we'll blame the intern or the nurse, you know they put them on oxygen and get a high sat what happens and and what do we need to do when that happens.
