Carbon monoxide attaches to red blood cells, robbing oxygen from your body it needs to thrive. It mixes with these cells nearly 200 times more easily than oxygen, creating a condition known as carboxyhemoglobin saturation.
Carbon monoxide, in place of oxygen, then gets carried to the vital organs by the bloodstream. To put it simply, carbon monoxide robs your body of oxygen. Organs require oxygen; when they lack it, they begin to suffocate.
Your body takes a long time to eradicate carbon monoxide; however, it can be absorbed much more quickly.
