Carbon monoxide attaches to red blood cells, stealing oxygen from your body it needs to survive. It mixes with these cells over 200 times more easily than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, on lieu of oxygen, then gets brought to the essential organs through the bloodstream. In short, carbon monoxide robs your body of oxygen. Organs need oxygen; when they lack it, they begin to suffocate.
Your body requires a long time to eradicate carbon monoxide; however, it can be taken in much faster.
