The Pulmonary Function Test (PFT) is a diagnostic procedure that evaluates lung function and capacity. It includes several tests such as spirometry, lung volume tests, and diffusion capacity tests. These tests measure airflow, lung volumes, and gas exchange, providing crucial information for diagnosing lung conditions.
Common indications for PFTs include shortness of breath, persistent coughing, and wheezing. These tests are essential for evaluating respiratory symptoms and monitoring chronic lung conditions.
To prepare for a PFT, patients may need to avoid certain medications and follow specific instructions provided by their healthcare provider. During the test, patients breathe into a mouthpiece connected to a machine that measures lung function parameters.
PFTs help identify various lung conditions, such as asthma, chronic obstructive pulmonary disease (COPD), and interstitial lung disease. Based on the results, individualized treatment plans may involve medications, lifestyle changes, or further diagnostic evaluations.
Pulmonary function testing is a safe and effective way to assess respiratory health, guide treatment decisions, and monitor disease progression or improvement.
