Question

Quizplus · Accepted Answer

Arterial blood gases are the best diagnostic test to monitor acid-base balance in patients with COPD. This test measures the levels of oxygen and carbon dioxide in the blood, as well as pH, bicarbonate, and oxygen saturation. It provides important information about a patient's respiratory status and helps guide treatment decisions. Pulse oximetry measures oxygen saturation but does not provide information about acid-base balance, while bronchoscopy and sputum studies are used to evaluate the airways and identify infections or other respiratory problems, but do not specifically monitor acid-base balance.
