pulmonary function tests

Pulmonary function tests (PFTs) assess how well your lungs are working. They measure various aspects, including lung capacity, airflow, and gas exchange. During these tests, you might breathe into a device called a spirometer, which records how much air you inhale and exhale. PFTs help identify conditions like asthma, chronic obstructive pulmonary disease (COPD), and other respiratory issues. The results guide doctors in diagnosing and treating lung diseases, ensuring that you receive the right care based on your lung function.
