Pulmonary Function Test in Bangalore – Everything You Need to Know
Breathing is something most of us take for granted—until we start experiencing difficulties. Whether it’s due to asthma, chronic obstructive pulmonary disease (COPD), or unexplained shortness of breath, identifying the root cause is crucial for proper treatment. One of the most effective diagnostic tools for lung health is a Pulmonary Function Test in Bangalore, a non-invasive method used to evaluate how well your lungs are working.
This guide covers what the test is, why it’s done, what to expect, and how it can help in managing respiratory health.
What is a Pulmonary Function Test?
A pulmonary function test (PFT) is a group of tests designed to measure lung capacity, airflow, and gas exchange. It helps doctors determine how well your lungs are functioning by evaluating:
- How much air you can inhale and exhale
- How quickly you can exhale
- How efficiently oxygen passes from your lungs into your blood
These tests are painless, safe, and usually completed within an hour.
Why Do Doctors Recommend Pulmonary Function Tests?
Pulmonary function tests are often ordered when patients experience breathing difficulties, unexplained coughing, or chronic respiratory issues. Doctors use them to:
- Diagnose lung conditions such as asthma, COPD, and interstitial lung disease
- Monitor the progression of chronic respiratory illnesses
- Evaluate lung function before surgery
- Assess how well treatments are working
By identifying abnormalities early, patients can receive timely interventions that significantly improve their quality of life.
Different Types of Pulmonary Function Tests
Pulmonary function tests are not a single test but a combination of different evaluations. The most common ones include:
1. Spirometry
Measures how much air you can exhale and how fast. It is commonly used for asthma and COPD diagnosis.
2. Lung Volume Measurement
Determines the total amount of air your lungs can hold. Helpful in detecting restrictive lung diseases.
3. Diffusion Capacity Test
Evaluates how well oxygen passes from your lungs into your bloodstream.
4. Body Plethysmography
Provides detailed measurements of lung volumes using a sealed chamber for precise results.
Who Should Consider Getting a Pulmonary Function Test?
You may be advised to undergo the test if you have:
- Persistent coughing or wheezing
- Chronic shortness of breath
- Chest tightness
- A history of smoking
- Occupational exposure to dust, fumes, or chemicals
- Family history of lung diseases
Athletes and individuals preparing for surgery may also undergo PFTs to ensure their lung capacity is within a healthy range.
Preparing for the Test
To get accurate results, preparation is important:
- Avoid heavy meals before the test
- Do not smoke for at least 4–6 hours prior
- Refrain from using inhalers unless instructed by your doctor
- Wear loose, comfortable clothing to ease breathing movements
What Happens During the Test?
The test is simple and painless. Here’s what typically happens:
- You’ll be seated and asked to breathe into a mouthpiece connected to a machine.
- A nose clip may be used to prevent air leakage.
- You’ll perform different breathing patterns—deep inhalations, forceful exhalations, or steady breathing.
- The technician records the results, which are then analyzed by a pulmonologist.
The entire process usually takes 30–60 minutes.
Understanding the Results
Your test results will be compared against predicted values based on your age, height, gender, and ethnicity. The doctor will then:
- Identify whether you have normal lung function
- Detect restrictive or obstructive lung patterns
- Recommend medications, inhalers, or lifestyle changes
- Suggest further imaging or blood tests if needed
Benefits of Pulmonary Function Tests
- Early Detection: Identifies lung issues before symptoms worsen
- Treatment Monitoring: Helps track how effective your medications are
- Pre-Surgical Safety: Ensures your lungs can handle anesthesia
- Personalized Care: Results guide doctors in creating the right treatment plan
Risks and Limitations
Pulmonary function tests are generally safe. However, some people may feel lightheaded, short of breath, or dizzy during the test. These effects are temporary and subside quickly.
Patients with severe respiratory distress or recent heart problems may need additional evaluation before undergoing the test.
