Carbon monoxide connects to red blood cells, robbing your body of the oxygen it requires to live. It combines with these cells nearly 200 times more easily than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, instead of oxygen, then gets carried to the critical organs by the bloodstream. In short, carbon monoxide robs your body of oxygen. Organs require oxygen; without it, they begin to suffocate.
Your body requires a long time to eradicate carbon monoxide; however, it can be drawn in much more rapidly.
