Haemoglobin carrying carbondioxide is carbaminohaemoglobin while haemoglobin bound to carbonmonoxide is carboxyhaemoglobin.

Explanation:

Around 23% of carbondioxide produced in tissues are carried by haemoglobin of red blood cells as carbaminohaemoglobin.

Carbondioxide is unloaded at pulmonary capillaries around lungs as oxygen starts entering the blood.

Compared to this carboxyhaemoglobin is far more stable compound. Once formed carbonmonoxide do not leave haemoglobin, hence oxygen carrying capability of blood decreases.
