About PFT

Pulmonary Function Test (PFT) Services at Nano Hospitals are specialized diagnostic tests used to evaluate how well the lungs are working. These tests measure lung capacity, airflow, and gas exchange to help diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, and other breathing disorders.

Overview

Pulmonary Function Tests are a group of non-invasive breathing tests that assess how efficiently the lungs inhale, exhale, and transfer oxygen into the blood. The most common component is spirometry, which measures airflow and lung volume.

At Nano Hospitals, PFT services are conducted using advanced computerized systems that provide accurate and detailed reports for respiratory evaluation.

Workflow

Step 1: Medical Evaluation
A doctor recommends PFT if a patient has chronic cough, breathlessness, wheezing, or requires monitoring of a known lung condition.

Step 2: Test Preparation
The patient is guided on proper breathing techniques. Tight clothing and heavy meals are usually avoided before testing.

Step 3: Spirometry Testing
The patient breathes into a mouthpiece connected to a spirometer, following instructions to inhale and exhale forcefully.

Step 4: Additional Lung Measurements
Depending on the requirement, lung volumes and diffusion capacity tests may also be performed.

Step 5: Analysis and Reporting
Results are analysed by specialists to identify airflow limitation, lung restriction, or gas exchange problems.

Benefits & Value

For Patients

Early detection of lung diseases
Better management of asthma and COPD
Monitoring of treatment response and disease progression

For Doctors

Objective assessment of lung function
Helps differentiate between obstructive and restrictive lung disease
Guides medication adjustments and therapy plans

For the Community

Improved awareness and screening of respiratory diseases
Better long-term management of chronic lung conditions
Reduced hospitalizations due to early intervention

Risks & Challenges

  • Temporary dizziness or shortness of breath during forceful breathing
  • May be difficult for very elderly or severely breathless patients
  • Requires patient cooperation for accurate results
  • Not suitable during acute severe respiratory distress

Frequently Asked Questions

Usually 20–40 minutes.

Do I need to fast before a PFT?
Fasting is not required, but heavy meals should be avoided.

Can children undergo PFT?
Yes, if they are old enough to follow breathing instructions.

Is PFT safe?
Yes, it is a safe and routine diagnostic test.
