Carbon monoxide connects to red blood cells, stealing oxygen from your body it has to have to survive. It combines 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 taken to the important organs through the bloodstream. In short, carbon monoxide deprives your body of oxygen. Organs need oxygen; without it, they begin to suffocate.
It takes your body a long time to eliminate carbon monoxide; however, it can be absorbed much faster.
