A member asked:

If someone has a bruised lung from car wreck and sent home from hosp, how bad is it if their o2 sat is 80percent while on 30 percent oxygen?

A doctor has provided 1 answer

Any O2: Saturation below 92% is abnormal and below 89% is dangerous. If spo2 of 80% on 30% oxygen is true figure, it is very dangerously low. This person should be in the ICU at the hospital.
