Carboxy haemoglobin is ––– times more stable than oxyhaemoglobin

Carbon monoxide is poisionous gas. Since it combines with haemoglobin of blood and forming the stable carboxy haemoglobin complex irresveresibly hence the oxgyen transportation by haemoglobin decreases . Hence man dies in an atmoshere of high concentration of carbon monoxide. The anti dote used for the poisinous effect of carbon monooxide is carbogen. carbogen is a mixture of  Hb+O2⇌HbO24 Oxyhaemoglobin CO+Hb→(Hb←  CO) Carboxy haemoglobin CO2(10%)+O2(80%)Carboxyhaemoglobin is 300 times more stable than oxyhaemoglobin
