A Pulmonary Function Test (PFT) is a series of tests that measure how well your lungs work. It evaluates lung capacity, airflow, and the ability to transfer oxygen into the blood.
Indications for Pulmonary Function Test:
● Chronic respiratory conditions: PFT is used to diagnose asthma, COPD, and other lung diseases.
● Pre-surgical evaluations: It helps evaluate lung health before surgeries like lung resection or general anesthesia.
● Occupational exposure: For people exposed to dust, chemicals, or asbestos at work, PFT is used to monitor lung function.
How Pulmonary Function Test Works:
● PFT is performed using a spirometer to measure parameters like forced vital capacity (FVC), forced expiratory volume (FEV1), and peak expiratory flow rate (PEFR).
Normal Range:
● Normal values depend on age, gender, and height, but typically show normal airflow, lung capacity, and oxygen transfer.
Abnormal Test Significance:
● Obstructive patterns: Reduced airflow and FEV1 values, common in conditions like asthma or COPD.
● Restrictive patterns: Reduced lung volume, indicating conditions like pulmonary fibrosis.
Management Based on Results:
● For obstructive diseases: Medications like bronchodilators and steroids are used.
● For restrictive diseases: Treatment may involve oxygen therapy or rehabilitation.
Price in India:
● Approx. ₹1,500 – ₹5,000 for a Pulmonary Function Test.
Frequently Asked Questions
How is a pulmonary function test performed?
The patient breathes into a machine called a spirometer to measure airflow and lung capacity.
How do I prepare for a PFT?
Avoid bronchodilators and heavy meals before the test.
Disclaimer: PFTs are essential for diagnosing lung diseases, but abnormal results should be discussed with a pulmonologist for appropriate management.
