Carbon monoxide attaches to red blood cells, robbing your body of the oxygen it has to have to live. It mixes with these cells more than 200 times more smoothly than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, in place of oxygen, then gets carried to the important organs by the bloodstream. Simply put, carbon monoxide deprives your body of oxygen. Organs need oxygen; when they lack it, they begin to suffocate.
It takes your body a long time to eradicate carbon monoxide; however, it can be drawn in much more rapidly.
