A Pulmonary Function Test (PFT) is a non-invasive diagnostic procedure that evaluates the functioning of the lungs. This test measures lung volume, capacity, flow rates, and gas exchange efficiency to assess how well your lungs are delivering oxygen to your bloodstream. By analyzing the results, pulmonologists can diagnose a variety of respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and interstitial lung diseases.
A PFT is recommended when an individual experiences persistent respiratory symptoms like shortness of breath, chronic cough, wheezing, or reduced exercise tolerance. It is also essential for those with a history of smoking, exposure to occupational pollutants, or pre-existing lung conditions. Additionally, PFTs are commonly conducted before surgeries to evaluate lung function and during treatment to monitor the progress of lung diseases.
Pulmonary Function Tests offer a range of benefits in respiratory care. They help in early diagnosis of lung disorders, enabling timely and effective treatment. PFTs provide critical insights into the severity of lung conditions and their impact on daily activities. Moreover, they aid in tailoring personalized treatment plans and monitoring the effectiveness of therapies, ensuring better health outcomes for patients.
