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.
