Endobronchial Ultrasound (EBUS): A Guide for Patients

Written By growzacompany .

Introduction

Have you been feeling breathless even during mild exertion? Do you suffer from a chronic cough or unexplained fatigue? These symptoms may indicate an underlying lung condition that needs medical evaluation.

Lung function testing plays a vital role in detecting respiratory disorders early—before they become more serious. Two of the most essential tests used by pulmonologists are Pulmonary Function Testing (PFT) and the Diffusing Capacity of the Lung for Carbon Monoxide (DLCO).

In this guide, we break down what these tests involve, why they matter, and how getting a PFT or DLCO test in Kolkata from a trained expert like Dr. Ayush Goel can provide clarity and help you breathe easier.

What is Pulmonary Function Testing (PFT)?

PFT is a group of non-invasive tests that measure how well your lungs are functioning. The data helps assess:

  • Lung volume: How much air your lungs can hold

  • Airflow: How quickly you can exhale

  • Gas exchange: How efficiently oxygen and carbon dioxide are transferred between lungs and blood

These tests are crucial for diagnosing and managing conditions like:

  • Asthma

  • Chronic Obstructive Pulmonary Disease (COPD)

  • Interstitial Lung Disease (ILD)

  • Restrictive or obstructive airway disorders

What is DLCO Testing?

The DLCO test (Diffusing Capacity of the Lung for Carbon Monoxide) measures how effectively your lungs can transfer oxygen from the air sacs into your bloodstream.

This test is especially useful in detecting early signs of damage to the alveoli, the tiny air sacs in your lungs.

Conditions where DLCO plays a key role:

  • Pulmonary fibrosis

  • ILD (Interstitial Lung Disease)

  • Pulmonary hypertension

  • Emphysema

  • Anemia-related breathing issues

In a city like Kolkata, where environmental pollution and allergens are common, timely testing can be life-saving.

When Are PFT and DLCO Tests Recommended?

Your lung function testing doctor in Kolkata may recommend these tests under the following circumstances:

  • You experience persistent shortness of breath

  • Chronic cough that doesn't respond to medication

  • Abnormal chest X-ray or CT scan with unclear cause

  • Wheezing or exercise intolerance

  • Monitoring disease progression in asthma, COPD, or ILD

  • Pre-operative lung assessment for surgeries involving the chest or major organs

These tests help identify the exact nature and extent of the lung issue, allowing for personalized treatment.

How These Tests Are Performed

Pulmonary Function Test (PFT) Procedure:

  • You’ll be seated and asked to breathe into a device called a spirometer

  • You may perform deep breaths and forced exhalations multiple times

  • Total test duration: 20–30 minutes

DLCO Test Procedure:

  • You will inhale a small, harmless amount of carbon monoxide gas

  • Hold your breath for about 10 seconds

  • The exhaled air is analyzed to calculate how much gas your lungs absorbed

Both tests are safe, painless, and require only basic cooperation.

Why PFT and DLCO Matter

These tests provide critical insights into your lung function that simple X-rays or symptom evaluation cannot offer.

1. Early Detection

They can reveal problems before symptoms become severe, allowing for early intervention.

2. Accurate Diagnosis

They help differentiate between diseases like asthma, COPD, or ILD, which may have overlapping symptoms.

3. Treatment Planning

Lung test results help pulmonologists prescribe the right medications, therapies, or lifestyle changes.

4. Progress Monitoring

These tests are used over time to track if your lung disease is improving, worsening, or remaining stable.

5. Surgical Risk Assessment

Before undergoing surgeries, especially for cancer or heart problems, your lung function must be evaluated.
