Understanding your lung health is crucial, especially if you're experiencing breathing difficulties or chronic respiratory conditions. At JCS Lung and Sleep Centre, we provide an advanced Pulmonary Function Test in Delhi to accurately assess your respiratory system. These tests not only help diagnose lung disorders but also guide effective treatment plans.
What Is a Pulmonary Function Test (PFT)?
A Pulmonary Function Test, or PFT, is a non-invasive procedure that evaluates how well your lungs are functioning. It measures several critical aspects, including:
- Lung volume
- Capacity
- Rates of flow
- Gas exchange efficiency
These indicators help pulmonologists detect diseases like asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and more.

Benefits of Undergoing a PFT
A Pulmonary Function Test in Delhi can be beneficial in multiple ways:
- Early diagnosis of lung conditions
- Evaluation of how chronic diseases are affecting lung performance
- Monitoring of treatment effectiveness
- Pre-surgical assessment for lung capacity
As a result, early intervention becomes possible, significantly improving quality of life.
When Should You Get a Pulmonary Function Test?
There are several scenarios when a PFT is advised. For example:
- Persistent cough or shortness of breath
- Wheezing or tightness in the chest
- History of smoking or exposure to harmful pollutants
- Monitoring of lung condition or medication response
- Pre-employment screening in certain professions
Therefore, if you fall into any of these categories, getting tested can help you stay ahead of potential issues.
Types of Pulmonary Function Tests
At our Delhi facility, we offer a wide range of PFTs, including:
- Spirometry – Measures airflow and capacity
- Lung Volume Test – Assesses the total volume of air in the lungs
- Diffusion Capacity Test – Evaluates how well gases are exchanged in the lungs
- Bronchoprovocation Test – Checks airway sensitivity
Each test serves a specific purpose, allowing a comprehensive view of lung health.
How to Prepare for a PFT
Preparing for a Pulmonary Function Test is simple, but a few steps can ensure accurate results:
- Avoid smoking 24 hours before the test
- Don’t eat a heavy meal beforehand
- Wear loose, comfortable clothing
- Follow medication instructions given by your doctor
Additionally, if you have a cold or feel unwell, reschedule the test to avoid skewed results.
What to Expect During the Procedure
The test usually takes 30–60 minutes and is entirely safe. Here’s what happens:
- You’ll be asked to breathe in and out through a mouthpiece
- Nose clips may be used to prevent air from escaping

Although the test may feel tiring, it’s pain-free and offers invaluable insights into your health.
