Smoking Poison

So here's an interesting fact. Let's assume I was unfortunate enough to suffer from carbon monoxide (CO) poisoning. This could happen because of a faulty furnance or a house fire (among other things). If I was a smoker and my CO level at the hospital was <10%, no one would likely get too excited. If I was a non-smoker and my CO level at the hospital was <3%, no one would likely get too excited. Notice a difference?

The point is smokers can walk around with a CO level that is equivalent to CO poisoning. Even if a smoker is involved in a CO poisoning incident, it may be hard to tell because they may live with a chronic CO level of up to 10%. Anything over 3% in a non-smoker would be cause for treatment with 100% oxygen and maybe even hyperbaric oxygen treatment. If you're a smoker...not so much, you may live at that level already.

Why should the hospital get excited about your acute CO poisoning when you've been doing it to yourself chronically already?
