Pulmonary Function Testing
Measuring how well your lungs work
Why lung function tests matter
Symptoms such as breathlessness and cough can have many causes. Pulmonary function tests (PFTs) measure how much air your lungs hold, how quickly you can move air in and out, and how well oxygen passes into your blood.
The results help distinguish asthma from COPD, detect restrictive lung disease such as ILD, assess fitness before surgery, and show whether treatment is working.
Tests may be advised for
- Persistent cough or breathlessness
- Asthma and COPD diagnosis
- Monitoring interstitial lung disease
- Pre-operative assessment
- Smokers with symptoms
- Occupational lung exposure
Tests & services
Spirometry
The most common breathing test — measures how much air you can blow out and how fast.
Bronchodilator Reversibility Testing
Spirometry repeated after an inhaled bronchodilator to see whether airway narrowing improves.
Six-Minute Walk Test
Measures how far you can walk in six minutes and how your oxygen level responds.
Advanced Pulmonary Function Testing
A complete assessment of lung volumes, airflow and gas transfer for complex breathing problems.
Frequently asked questions
Avoid smoking, heavy meals and vigorous exercise before the test, and wear loose clothing. You may be asked to stop certain inhalers for a few hours beforehand — follow the specific instructions you are given.
Spirometry takes about 15–20 minutes. A complete set of advanced tests may take 45–60 minutes.
Yes. They are non-invasive. Some people feel briefly light-headed from the breathing efforts. Tests may be deferred after recent heart attack, eye or chest surgery, or during an acute illness.
Spirometry, bronchodilator reversibility testing, complete pulmonary function testing and the six-minute walk test are available at Anandam Hospitals. Your doctor will advise which tests you need.
