Carbon monoxide connects with red blood cells, stealing oxygen from your body it needs to live. It combines with these cells more than 200 times more easily than oxygen, resulting in a condition known as carboxyhemoglobin saturation.
Carbon monoxide, in place of oxygen, then gets brought to the essential organs via the bloodstream. Simply put, carbon monoxide starves 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 absorbed much faster.
