Carbon Monoxide Headquarters

Chronic CO Poisoning:

A Paradox of CO Physiology:


  • It limits oxygen delivery, binds to intracellular energy generating system, kills cells, causes damage to tissues and organs, and kills people.

    Natural / Helpful:

  • It is generated by the human body as a by-product of hemoglobin metabolism

  • Along with NO (nitric oxide), it is an integral part of the vascular control mechanism.

  • Most blood vessels dilate as COHb increases, allowing more blood to flow through.
