A Pulmonary Function Test, commonly known as spirometry, is the gold standard for objective respiratory assessment. It gives measurable data that guides clinical decisions.

How It Works

The patient breathes into a device with coaching. The procedure is non-invasive, safe, and usually takes 15 to 30 minutes.

Why Doctors Use It

PFT helps diagnose disease, grade severity, and track treatment response. It is useful in asthma, COPD, fibrosis, and unexplained breathlessness.

Children and Spirometry

Many children from about 5 to 6 years can perform acceptable spirometry with proper encouragement and technique.
