Chronic Obstructive Pulmonary Disease (COPD) Definition: Arterial blood gases (ABGs) are diagnostic tests performed on blood taken from an artery which contains oxygen and carbon dioxide. The Purpose of the ABG. ABGs measure how well the lungs can provide adequate oxygen to the body and subsequently remove carbon dioxide. Analysis of blood gases helps evaluate a person's respiratory and metabolic status. ABGs also measure blood pH and the integrity of the body's acid-base balance.
A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a blood gas analysis or arterial blood gas (ABG) test. Your red blood cells transport oxygen and carbon dioxide throughout your body. These are known as blood gases. As blood passes through your lungs, oxygen flows into the blood while carbon dioxide flows out of the blood into the lungs.
