Carbon monoxide connects with red blood cells, robbing oxygen from your body it requires to live. It blends with these cells nearly 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 by the bloodstream. Simply put, carbon monoxide starves your body of oxygen. Organs have to have 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.
