What does ABG stand for in medical terminology?

In medical terminology, ABG stands for arterial blood gas. This term refers to a test that measures the levels of oxygen and carbon dioxide in the blood, as well as the pH level. It is an important diagnostic tool used to assess a patient's respiratory and metabolic status. The test helps in evaluating how well the lungs are functioning in terms of gas exchange and can provide critical information in diagnosing various conditions such as respiratory failure, metabolic disorders, and critically ill patients. Understanding ABGs is essential for healthcare professionals, especially when monitoring a patient's respiratory health or making decisions regarding treatment interventions.
