What Is an Arterial Blood Gas Test? An arterial blood gas test, commonly known as an ABG, is performed on blood from an artery. It is used to see how well the lungs are functioning and to determine the effectiveness of respiratory therapies, such as the use of a ventilator, CPAP, BiPAP or oxygen.
The test shows the size and shape of your heart and how well your heart chambers and valves work. Echo also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and heart muscle damage caused by lack of blood flow. Echo might be done before and after a stress test (see below). A stress echo can show how well blood is flowing through your heart.
