Carbon monoxide attaches to red blood cells, robbing your body of the oxygen it needs to thrive. It blends with these cells over 200 times more easily than oxygen, resulting in a condition known as carboxyhemoglobin saturation.
Carbon monoxide, on lieu of oxygen, then gets carried to the important organs by the bloodstream. In short, carbon monoxide robs your body of oxygen. Organs require oxygen; when they lack it, they begin to suffocate.
Your body needs a long time to eradicate carbon monoxide; however, it can be drawn in much more quickly.
