    Blood analysis of a patient reveals an unusually high quantity of carboxyhaemoglobin content. Which of the following conclusions is most likely to be correct? The patient has been inhaling polluted air containing unusually high content of

    A)  Chloroform

    B)  Carbon dioxide

    C)  Carbon monoxide

    D)  Carbon disulphide

    Correct Answer: C

    Solution :

     Carboxyhaemoglobin, a stable compound, is formed when haemoglobin readily combines with carbon monoxide. Carbon monoxide converts (II) to iron (III) in its reaction with haemoglobin. In this form haemoglobin does not carry oxygen resulting in its (oxygen) starvation and leads to asphyxiation and in extreme cases to death. The affinity of haemo- globin for CO is 250 times its affinity for\[{{O}_{2}}\]and COHb liberates CO very slowly and also due to that compound the dissociation curve of the remaining\[Hb{{O}_{2}}\] shifts to the left, decreasing the amount of \[{{O}_{2}}\]released.
