Somebody who oughta know told me that co exposure is accumulative; what you breathed yesterday is still in the system. Is that true? Or does it dissipate quickly?

: just to clarify the facts

: the problem with co is not that it takes an extra oxygen out of the air and
: one loses all the oxygen (normal combustion consumes two o's for each c).

: the problem is that when co is inhaled (breathed) it binds to the hemoglobin
: in ;one's blood with an affinity that is over thirty times as strong as
: the affinity of oxygen for hemoglobin. it is the hemoglogin in the red
: blood cells that caries the oxygen to the individual cells in the body.
: the oxygen is necessary to keep the cells alive. the neural tissue (read
: brain) is probably the most sensitive to oxygen depravation.

: what this means is that the co blocks the ability of the blood to carry
: oxygen to the tissues and cells (brain cells in particular) die after a
: short time without oxygen. one gets "gorked".

: just for accuracy.
