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
  • 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.
  • 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.
