Carbon monoxide connects to red blood cells, robbing oxygen from your body it needs to survive. It combines with these cells over 200 times more easily than oxygen, resulting in a condition known as carboxyhemoglobin saturation.
Carbon monoxide, instead of oxygen, then gets taken to the vital organs through the bloodstream. Simply put, carbon monoxide deprives your body of oxygen. Organs require oxygen; without it, they begin to suffocate.
It takes your body a long time to eradicate carbon monoxide; however, it can be taken in much faster.
