Pulmonary Function Tests (PFT) in Tamil Nadu

Is the pulmonary function test uncomfortable?

It is non-invasive and generally well tolerated, requiring you to breathe forcefully into a mouthpiece, though some people feel briefly lightheaded or fatigued from the deep breathing effort.

How should I prepare for a PFT?

Avoid smoking, heavy meals, and strenuous exercise for a few hours before the test, and check with your doctor about whether to hold certain inhalers beforehand as instructed.

How long does the test take?

The full assessment usually takes 30-60 minutes, including instructions, several practice breaths, and repeat measurements for accuracy.

When will I get my results?

Results are often available immediately or within 24 hours, and your pulmonologist will explain what the values mean for your specific condition.

Can I do a PFT if I have a cold or chest infection?

It's best to postpone the test until you recover, as an active respiratory infection can temporarily lower your results and affect accuracy; consult your doctor on timing.
