An Arterial Blood Gas (ABG) test measures the amounts of arterial gases, such as oxygen and carbon dioxide. Small amount of blood is drawn from arteries, which can be, Radial artery, Femoral artery, Brachial artery or another suitable one. An ABG test measures the blood-gas tension values of the arterial partial pressure of oxygen, and the arterial partial pressure of carbon dioxide, and the blood’s pH. In addition, the arterial oxygen saturation can be determined.
