A Pulmonary Function Test, commonly known as PFT, is a simple, non-invasive test that tells how well your lungs are working. It helps measure how much air you can inhale and exhale, and how efficiently your lungs can move oxygen into your blood.
Whether you have breathing problems or just want to check your lung health, a PFT gives valuable insights into your respiratory system.
Your doctor may recommend a PFT if you have:
Breathing difficulties, such as shortness of breath
Chronic cough, wheezing, or chest tightness
A history of smoking or exposure to pollution or dust
Known lung conditions like Asthma, COPD, or Pulmonary Fibrosis
To monitor lung function before surgery
To assess how well current medications or treatments are working
During the test:
You’ll be asked to breathe into a special mouthpiece connected to a machine called a spirometer.
You may be asked to take deep breaths in and out, or blow as hard and fast as you can.
The test usually takes 20–30 minutes and is completely safe and painless.
You may need to avoid heavy meals, smoking, or certain medications before the test—your doctor will guide you.
PFTs help diagnose and monitor conditions like:
Asthma
Chronic Obstructive Pulmonary Disease (COPD)
Bronchitis
Lung scarring (fibrosis)
Allergic lung disease
Effects of occupational or environmental exposures
