Carbon monoxide connects with red blood cells, robbing oxygen from your body it needs to live. It blends with these cells over 200 times more smoothly than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, in place of oxygen, then gets brought to the important organs through the bloodstream. To put it simply, carbon monoxide deprives your body of oxygen. Organs need oxygen; when they lack it, they begin to suffocate.
Your body takes a long time to eradicate carbon monoxide; however, it can be drawn in much faster.
