Carbon monoxide attaches to red blood cells, robbing 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. To put it simply, carbon monoxide deprives your body of oxygen. Organs need oxygen; when they don’t have it, they begin to suffocate.
It takes your body a long time to eradicate carbon monoxide; however, it can be drawn in much faster.
