Thanks for the corrections. I remembered that it was a pretty significant number.
and the worst thing is that the very high affinity CO has for hemoglobin in our blood, means that it takes days to rid our body of the poisoning effects.
So the best analogy I can think of, is you have a rope around your neck, strangling you. cutting off oxygen to your brain. too tight and the brain starts to have cells die. and if the rope gets tight enough, YOU die or suffer perminant brain damage..
But just loosening the rope, even removing it doesn't restore full oxygen to the brain,, it's like this rope leaves a severe depression in your neck, still crushing the blood vessels supplying the brain.. and only time breathing 100% Oxygen will slowly allow the blood flow to get back to normal..
The bottom line is that CO is very dangerous, and must be taken seriously.
