Q. Blood analysis of a patient reveals an unusually high quantity of carboxyhaemoglobin content. Which of the following conclusions is most likely to be correct?
A) Carbon disulphide the patient has been inhaling polluted air containing usually high content of
B) Chloroform the patient has been inhaling polluted air containing usually high content of
C) Carbon dioxide the patient has been inhaling polluted air containing usually high content of
D) Carbon monoxide the patient has been inhaling polluted air containing usually high content of
Explanation
Carbon monoxide forms a stable compound with haemoglobin called carboxyhaemoglobin as affinity of haemoglobin for carbon monooxide is 250 times greater than its affinity for oxygen. In this form, haemoglobin does not carry oxygen resulting in death too. Hb + CO $\rightarrow$ Hb CO Haemoglobin Carboxyhaemoglobin
