Arterial blood gas

Arterial blood gas (ABG) is a test that measures the levels of oxygen and carbon dioxide in your blood, along with its acidity (pH). It helps doctors assess how well your lungs are exchanging gases and how effectively your body's organs are functioning. By analyzing these components, healthcare providers can diagnose respiratory or metabolic problems, guide treatment, and monitor your condition, especially in situations like breathing difficulties or critical illness. The test involves drawing a small blood sample from an artery, usually in the wrist, providing crucial information about your respiratory and metabolic health.
