Question
Carbon monoxide poisoning.

Answer

$1.$ Carbon monoxide poisoning is caused when carbon monoxide is combined with haemoglobin.
$2.$ Haemoglobin is said to have $250$ times more affinity for carbon monoxide than that for the oxygen.
$3.$ Therefore, haemoglobin with carbon monoxide forms a stable compound, the carboxyhemoglobin.
$4.$ Due to the formation of carboxyhaemoglobin, the haemoglobin no longer carries oxygen to the cells and tissues. Tissues then suffer from oxygen starvation. This leads to asphyxiation and in extreme cases it leads to death.
$5.$ Carbon monoxide poisoning occurs in closed rooms with incompletely burning substances such as stove burners or furnaces and garages having running automobile engines.
$6.$ Person suffering from carbon monoxide poisoning has to be administered with oxygen$-$carbon dioxide mixture, so that high levels of $CO_2$ makes carbon monoxide dissociated from haemoglobin.
