Question

Quizplus · Accepted Answer

Pulmonary function studies are designed to measure various aspects of lung function, including lung volumes and capacities (to assess how much air the lungs can hold), pulmonary diffusion capacity (to evaluate how well the lungs can exchange gases), and forced expiratory flow rates (to determine how quickly a person can exhale air). These measurements help in diagnosing and monitoring lung diseases. Carbon monoxide levels are not directly assessed in pulmonary function tests; they are more relevant to poisoning cases or to assess smoking status and not lung function per se.
