Carbon monoxide connects to red blood cells, stealing oxygen from your body it requires to live. It mixes with these cells over 200 times more smoothly than oxygen, leading to a condition known as carboxyhemoglobin saturation.
Carbon monoxide, instead of oxygen, then gets carried to the important organs via the bloodstream. Simply put, carbon monoxide starves your body of oxygen. Organs require oxygen; without it, they begin to suffocate.
Your body requires a long time to get rid of carbon monoxide; however, it can be absorbed much faster.
