Carbon monoxide connects to red blood cells, robbing your body of the oxygen it requires to live. It combines with these cells over 200 times more easily than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, in place of oxygen, then gets brought to the critical organs through the bloodstream. Simply put, carbon monoxide robs your body of oxygen. Organs require oxygen; when they lack it, they begin to suffocate.
It takes your body a long time to get rid of carbon monoxide; however, it can be absorbed much faster.
