Pulmonary Function Test (PFT) includes a group of non-invasive tests that measure how well the lungs are working. These tests involve various measurements, including lung gas exchange, lung capacity, lung volume and Max.Airflow. They play a crucial role in pulmonary function diagnosing for pulmonary & lung diseases like Asthma, Chronic Obstructive Pulmonary Disease(COPD), Lung Interstitial Fibrosis , Lung Sarcoidosis, Reduced Lung Volume, Pulmonary Embolism, Pulmonary Hypertension, Pulmonary Hemorrhage, Chronic Shortness of Breath and etc.

In addition to diagnosis, Pulmonary function test are also used to monitor the progression of lung diseases and assess the effectiveness of treatment. By regularly performing these tests, healthcare providers can track changes in lung function over time and make adjustments to treatment plans as needed.

Furthermore, Pulmonary function test provide valuable information about how lung diseases impact overall health. For example, it can help determine if a patient's respiratory issues are affecting their ability to engage in physical activity, like help assess the respiratory system function of athletes or individuals involved in competitive sports, thereby optimizing their training programs. or Some occupations (such as miners and factory workers in chemical plants) may be exposed to harmful substances, and regular pulmonary function tests can monitor the lung health of these workers and detect problems in early stage.

Overall, pulmonary function tests are an essential tool for managing and treating various lung conditions. They provide objective data that guides medical decision-making and helps to improve patient’s life quality and better deal with respiratory issues.
