Under what circumstances can people be poisoned by carbon monoxide?

Indoor gas leakage and poor ventilation will lead to carbon monoxide poisoning.

Carbon monoxide poisoning is caused by inhaling products of incomplete combustion of carbonaceous materials through respiratory tract. The poisoning mechanism is that the affinity between carbon monoxide and hemoglobin is 200 ~ 300 times higher than that between oxygen and hemoglobin.

Therefore, carbon monoxide is easy to combine with hemoglobin to form carboxyhemoglobin, which makes hemoglobin lose its oxygen-carrying ability and function and causes tissue suffocation. It is toxic to tissues and cells all over the body, especially to the cerebral cortex.
