Pronunciation: /kärˌbäksēˌhēməˈɡlōbən/

A compound formed in the blood by the binding of carbon monoxide to hemoglobin. It is stable and therefore cannot absorb or transport oxygen.
Example sentences

  • When haemoglobin mixes with carbon monoxide it produces a compound called carboxyhaemoglobin.
  • Pulse oximetry cannot differentiate between oxyhaemoglobin and carboxyhaemoglobin, and may therefore give normal results.
