I know that it's best if your blood oxygen level is 92% or higher. Below that they tend to get worried and if your in the 80's they may put you on oxygen. But at what point is it actually dangerous? How low must it be to cause serious damage? I average about 94% but now that i'm living at high altitude (10,000+ feet) they are worried my O2 will dip dangerously low, especially while sleeping. How low is dangerous?
