What is the normal oxygen level for someone with COPD?

Medically reviewed by Carmen Pope, BPharm. Last updated on Dec 3, 2021.

Official answer


Between 88% and 92% oxygen level is considered safe for someone with moderate to severe COPD. Oxygen levels below 88% become dangerous, and you should ring your doctor if it drops below that. If oxygen levels dip to 84% or below, go to the hospital. Any level 80% and lower is dangerous for your vital organs and needs urgent treatment.
