Introduction
Asthma is a chronic respiratory condition affecting millions worldwide. In India, an estimated 34.3 million people suffer from asthma, with urban centers like Bangalore witnessing a higher prevalence due to increasing pollution levels (Global Burden of Disease Report, 2023). A Pulmonary Function Test (PFT) is a vital diagnostic tool for assessing lung function and aiding in effective asthma management.
If you’re looking for a Pulmonary Function Test for asthma in Bangalore, this guide provides everything you need to know, including its importance, types, procedure, costs, and where to get tested.
What is a Pulmonary Function Test (PFT)?
A Pulmonary Function Test (PFT) is a non-invasive assessment of how well your lungs function. It measures aspects such as:
- Lung volume: The amount of air your lungs can hold
- Airflow rates: The speed at which you can exhale
- Gas exchange: How efficiently oxygen enters the blood
For asthma patients, PFTs help diagnose, monitor severity, and guide treatment adjustments.
Why is a Pulmonary Function Test Important for Asthma?
- Accurate Diagnosis: Differentiates asthma from other lung diseases like COPD.
- Severity Assessment: Determines how well your lungs are functioning.
- Treatment Evaluation: Helps doctors decide if your medication needs adjustment.
- Early Detection: Identifies lung function decline before severe symptoms develop.
Types of Pulmonary Function Tests for Asthma
1. Spirometry
- Measures how much and how quickly you can exhale air.
- Used to assess airflow obstruction, a hallmark of asthma.
- FEV1/FVC ratio is a key indicator in asthma diagnosis.
2. Peak Expiratory Flow (PEF) Test
- Measures how fast you can exhale.
- Helps track asthma control over time.
3. Bronchoprovocation Test
- Involves inhaling substances like methacholine to check airway sensitivity.
- Used when spirometry results are inconclusive.
4. Plethysmography
- Measures lung volume for a detailed analysis.
- Useful in severe or uncontrolled asthma cases.
5. Gas Diffusion Test
- Evaluates how well oxygen transfers from the lungs to the blood.
How is a PFT Done?
- Preparation: Avoid heavy meals, smoking, and caffeine before the test.
- Procedure:
- You will breathe into a spirometer through a mouthpiece.
- Some tests require inhaling medication to assess response.
- Duration: Typically 30-60 minutes.
- Results: Compared to normal values to determine lung function.

Interpreting PFT Results for Asthma
- FEV1 (Forced Expiratory Volume in 1 Second):
- Normal: ≥80% of predicted value
- Mild Asthma: 60-80%
- Moderate Asthma: 40-60%
- Severe Asthma: <40%
- FEV1/FVC Ratio:
- Normal: ≥75%
- Asthma: <75% (reversible with bronchodilator use)
When Should You Get a PFT Done?
- If you experience symptoms like wheezing, shortness of breath, or chronic cough.
- For regular monitoring if you have an existing asthma diagnosis.
- Before adjusting medication to ensure effective treatment.
- If you have a family history of respiratory diseases.
Tips for Managing Asthma Based on PFT Results
- Follow a Personalized Treatment Plan: Work with your doctor to adjust medications based on PFT results.
- Avoid Triggers: Minimize exposure to dust, pollen, smoke, and air pollution.
- Regular Exercise: Opt for activities like swimming and yoga that improve lung capacity.
- Monitor Symptoms: Use a peak flow meter at home to track daily lung function.
- Annual PFTs: Recommended for asthma patients to monitor lung health.
