What does ABG stand for in medical assessments?

ABG stands for Arterial Blood Gas, which is a critical test in medical assessments, particularly in emergency and critical care settings. This test measures the levels of oxygen and carbon dioxide in the blood, as well as the blood's pH level. It provides essential information regarding a patient's respiratory and metabolic status, helping clinicians assess respiratory conditions, manage ventilator settings, and guide treatment decisions for various disorders such as asthma, chronic obstructive pulmonary disease (COPD), and acute respiratory distress syndrome (ARDS).

The ABG test is performed by drawing blood from an artery, typically the radial or femoral artery, which is rich in oxygen. The results reflect how well the lungs are functioning in gas exchange and how well the kidneys are managing acid-base balance. Recognizing the significance of arterial blood gas analysis is crucial for healthcare professionals as it significantly influences patient management in life-threatening situations.
