Definition of carboxyhaemoglobin in English:

carboxyhaemoglobin

noun kɑːˌbɒksɪˌhiːməˈɡləʊbɪn
mass nounBiochemistry
  • A compound formed in the blood by the binding of carbon monoxide to haemoglobin. It is stable and therefore cannot absorb or transport oxygen.

    Example sentencesExamples
    • What happens is the CO combines with the haemoglobin in the blood to form the relatively stable carboxyhaemoglobin and renders the blood ineffectual as an oxygen carrier.
    • If someone has the symptoms of CO poisoning, a blood sample will be taken to check the amount of carboxyhaemoglobin in the blood.
    • Pulse oximetry cannot differentiate between oxyhaemoglobin and carboxyhaemoglobin, and may therefore give normal results.
    • The presence of carboxyhaemoglobin also diminishes the oxygen held by the normal haemoglobin, which further compounds the hypoxic effect.
    • When haemoglobin mixes with carbon monoxide it produces a compound called carboxyhaemoglobin.
