Course Summary

The arterial blood gas test (ABG) is one of the most common and useful tests performed by medical professionals. The ABG checks a patient’s arterial blood to determine acidity and levels of oxygen and carbon dioxide in their blood. It is especially useful to determine whether oxygen therapy is working for a patient or to reveal important information about a patient’s metabolic state. The goal of ABG sampling is to assess the patient’s physiologic condition. Anatomical sites, techniques, and complications of the arterial blood gas test and ABG interpretation is discussed. Interpretation of venous blood gases and detailed discussion of acid-base disturbances are discussed separately.
