单词	carboxyhaemoglobin
释义	carboxyhaemoglobin /kɑːˌbɒksɪˌhiːməˈɡləʊbɪn / noun [mass noun] Biochemistry A compound formed in the blood by the binding of carbon monoxide to haemoglobin. It is stable and therefore cannot absorb or transport oxygen.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.
