What does ABGs stand for?

What does ABGs stand for?

• A. Arterial bio-gas signals, an obsolete test.
• B. Alveolar blood gases, a measure of lung function.
• C. Arterial blood gases, a measurement of oxygenation and acid/base balance in the blood.
• D. Arterial blood glucose signals, a measurement of glucose.

Answer: (C)

Arterial blood gases are a test that directly measures the gases and acid-base status of arterial blood to tell us how well oxygen is getting into the blood and how the body is handling acids and bases. It provides values like PaO2 (oxygenation), PaCO2 (carbon dioxide in the blood), pH, and bicarbonate, which together show whether a person is hypoxemic, hypercapnic, or has a metabolic or respiratory disturbance. This information is crucial for evaluating lung function, guiding ventilation and oxygen therapy, and monitoring critically ill patients. The other options don’t fit because ABG is not about glucose levels, nor is it a term for alveolar gases or an obsolete test, and the test is specifically about arterial blood, not arterial blood glucose signals.
