carboxyhemoglobin

(noun)

The stable complex of carbon monoxide with hemoglobin. It prevents the normal complexing with oxygen and thus leads to anoxia.

Examples of carboxyhemoglobin in the following topics:

  • Carbon Monoxide Poisoning

    • Carbon monoxide mainly causes adverse effects in humans by combining with hemoglobin to form carboxyhemoglobin (HbCO) in the blood.
    • Carboxyhemoglobin (HbCO) can revert to hemoglobin, but the recovery takes time because the HbCO complex is fairly stable.
    • This results following a recurrence of increased carboxyhemoglobin levels and this effect may be due to a late release of carbon monoxide from myoglobin, which subsequently binds to hemoglobin.

  • Physical Characteristics and Volume

    • Carbon monoxide poisoning causes bright red blood due to the formation of carboxyhemoglobin.
