Blood analysis of a patient reveals an unusually high quantity of carboxyhaemoglobin conten which of the following conclusions is most likely to be corectgt

A

The patient has been inhaling plluted air containing unsually high content of carbon disulphide

B

The patient has been inhaling polluted air containing unusually high content of chloroform

C

The patient has been inhaling polluted air containing unsually high content of carbon dioxide

D

The patient has been inhaling polluted air containing unsually high content of carbon monoxide

Text Solution

Verified by Experts

The correct Answer is:
D
Inhalaltion of polluted air causes increases in CO in the blood of a person carbon monoxiode forms a stable compound with haemoglobin called carboxy haemogloinb as affinity of Hb for CO is 210 times greater than its affinity for `O_(2)`. In this form haemoglobin does not carry oxygen resulting in death due to hypoxia
`Hb + CO hArr HbCO`
