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 to reflect the patient’s physiologic state is discussed.
