What term refers to tests that measure the function of the lungs?

The term that refers to tests measuring the function of the lungs is pulmonary testing. This type of testing encompasses various assessments designed to evaluate how well the lungs work, including their capacity to take in and utilize air, as well as their efficiency in gas exchange. Common pulmonary tests include spirometry, which measures airflow, and arterial blood gas tests, which assess the levels of oxygen and carbon dioxide in the blood.

In contrast, cardiovascular testing focuses on the heart and blood vessels, examining their performance and health rather than lung function. Muscular testing assesses the strength and endurance of muscles in various parts of the body, which is unrelated to lung function. Diagnostic imaging involves techniques such as X-rays or MRIs that visualize the internal structures of the body, but these methods do not directly measure lung function. Thus, pulmonary testing is the accurate term for tests specifically related to lung function evaluation.
