Spirometry, including graphic record, total pulmonary function test with or without flow volume loop, with or without maximal voluntary ventilation

AI EXPLANATION: A pulmonary function test is a noninvasive breathing assessment that measures how well your lungs are working. During the test, you breathe into a mouthpiece attached to a specialized recording device that tracks your lung volume, total capacity, and airflow rate. It evaluates both how much air your lungs can hold and how rapidly you can exhale air, helping healthcare providers check respiratory function and lung health.
