What is pft?

Pulmonary Function Test (PFT) is a medical test used to evaluate the functioning of the lungs. This test is used to detect respiratory disorders like asthma, emphysema, chronic bronchitis, lung cancer, and pulmonary fibrosis. The PFT tests the capacity of the lungs, how well air flows in and out of the lungs, and how effectively gas is exchanged in the lungs.

The test is carried out in a pulmonary function laboratory, where the patient may be asked to take deep breaths, blow air into a tube or inhale certain gases. The test is usually non-invasive and painless, and it usually takes about 30 minutes to complete. The results of the PFT can help the doctor diagnose conditions affecting the lungs and decide the best treatment options for the patient.

Overall, a PFT is an important diagnostic measure that helps evaluate the respiratory system, detect any abnormalities and also assesses how treatment is improving the lung function.
