I doubt it. If it doesn't seem to help the person's condition after 3
or 4 minutes, I'd stop, at least for a while.


If there is a difference between welding oxygen and medical Oxygen,

I think much more effort is put into purity, but the impurities in
welding oxygen wouldn't be so bad in an emergency.

can anyone prove to me the difference, if it's just a tag, that is not proof, Talk is not proof, Just answer the question if you know for sure....
