UPSC NDA-1 – 2018
Carbon monoxide has a much higher affinity for haemoglobin (about 200-250 times greater) than oxygen. When inhaled, CO binds to haemoglobin forming carboxyhaemoglobin (COHb), effectively reducing the capacity of the blood to transport oxygen. This leads to oxygen deprivation in the body’s tissues and organs.
