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.
An arterial blood gas (ABG) measures three components: pH, pCO2, pO2. All the other numbers on a blood gas are calculated. The bicarbonate (HCO3) value is calculated based on the measured pH and the measured pCO2, using the Henderson-Hasselbalch equation. The base excess (BE) is calculated using a similar equation.BG-A is a normal blood gas in room air. ABG-B (pH 7.20, pCO2 60, pO2 70, bicarb 24, BE -3) shows a patient with acute respiratory failure. The pH is less than 7.40 which means that the patient has an acidosis.
