Pulmonary Function Tests (PFTs) are essential diagnostic tools used to evaluate lung function and diagnose respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases. Among the critical parameters assessed in PFTs are Forced Vital Capacity (FVC), Forced Expiratory Volume in One Second (FEV1), and Total Lung Capacity (TLC). These metrics offer valuable insights into lung health and help guide treatment decisions. If you’re looking for a trusted PFT Test Centre in Delhi, Srivastava MRI and Imaging Centre provides accurate testing and expert analysis.
What Are Pulmonary Function Tests?
Pulmonary Function Tests are non-invasive procedures that measure how well your lungs work by assessing lung volume, airflow, and gas exchange efficiency. These tests are vital for diagnosing, monitoring, and managing various lung conditions.
Key PFT Parameters
1. Forced Vital Capacity (FVC)
FVC represents the maximum amount of air you can exhale forcefully after taking the deepest breath possible.
- Significance:
FVC helps identify restrictive lung diseases that limit lung expansion, such as pulmonary fibrosis or interstitial lung disease. - Normal Range:
Values vary based on age, gender, and physical characteristics, but a reduced FVC typically indicates restricted lung function.
2. Forced Expiratory Volume in One Second (FEV1)
FEV1 measures the volume of air exhaled in the first second of the FVC test.
- Significance:
FEV1 is a critical indicator of obstructive lung diseases like asthma and COPD. - FEV1/FVC Ratio:
This ratio differentiates between obstructive and restrictive lung conditions. A lower ratio usually indicates airway obstruction.
3. Total Lung Capacity (TLC)
TLC measures the total volume of air in the lungs after taking the deepest possible breath.
- Significance:
Abnormal TLC values can indicate restrictive lung diseases (low TLC) or conditions like emphysema, which result in lung hyperinflation (high TLC). - Assessment Method:
TLC is commonly measured using body plethysmography or gas dilution methods, both of which are available at leading diagnostic centres like Srivastava MRI and Imaging Centre.

Importance of PFT Results
Doctors use PFT results to:
- Diagnose conditions like asthma, COPD, or interstitial lung disease.
- Monitor disease progression over time.
- Evaluate the effectiveness of treatments, including inhalers and medications.
- Assess lung function before surgery or other medical interventions.

When Should You Get a PFT?
Your doctor may recommend a PFT if you:
- Experience persistent coughing, wheezing, or shortness of breath.
- Have a history of smoking or long-term exposure to pollutants.
- Need to assess lung function before undergoing surgery.
- Show symptoms of chronic respiratory conditions.
How to Prepare for a PFT
To get accurate results, follow these guidelines:
- Avoid heavy meals for at least 4 hours before the test.
- Refrain from smoking or using inhalers for 24 hours prior (as advised by your doctor).
- Inform your doctor about medications you’re currently taking.
- Wear loose, comfortable clothing to facilitate easy breathing.
