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.
Because of the pumping pressure generated in the heart, arterial blood travels with a very high pressure. Therefore, during an arterial bleeding, blood spouts unevenly due to the high pressure. Arterial blood irrigates the tissues with oxygen and nutrients, as it is rich with those constituents. However, it lacks carbon dioxide, urea, and other waste products of the body. Venous Blood.
