Pulmonary Function Tests at Center (PFT)

The Pulmonary Function Tests (PFT) play a key role in identifying, treating, and monitoring diseases and disorders like asthma, chronic obstructive pulmonary disease (COPD), and other lung diseases. These tests are most often done when there are symptoms that point towards lung issues like chronic cough, breathlessness, etc., or in the case of abnormal findings on chest X-rays. These are also done as routine check-ups in people with known lung diseases or those who are at increased risk for lung illness because of reasons such as smoking or exposures at work. Also, PFTs are occasionally done prior to major surgeries to determine a patient's lung function and suitability for anesthesia.

For PFT, an individual breathes into a spirometer, which detects the volume and rate of air inhaled and exhaled. PFT tests generally measure airflow (also called spirometry), measurement of lung volumes (to calculate total lung capacity), and diffusion capacity (to test the efficiency of gas exchange). Individuals may have to inhale medication or follow special breathing patterns to provide accurate test results.

Avoid consuming a large meal, alcohol, or smoking before taking these tests since these may impact the lung function. It is also advisable to steer clear of using inhalers or other breathing medications prior to the test unless directed otherwise by the physician. Dress in loose-fitting clothing that allows you to breathe freely during the test procedure. Also, refrain from exercising for 30 minutes prior to the tests.

Interpretation of PFT results requires professional expertise. Therefore, it is essential to consult the doctor to understand the implications of the PFT findings.
