Carbon monoxide connects with red blood cells, stealing oxygen from your body it requires to survive. It mixes with these cells over 200 times more smoothly than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, instead of oxygen, then gets brought to the essential organs by the bloodstream. In short, carbon monoxide robs your body of oxygen. Organs have to have oxygen; without it, they begin to suffocate.
Your body requires a long time to eradicate carbon monoxide; however, it can be absorbed much more quickly.
