Pulmonary Function Test (PFT / Spirometry / Spirogram)

Pulmonary Function Tests (PFTs) are a group of tests that measure how effectively the lungs take in air, hold air, and expel air. During the test, the patient exhales forcefully into a mouthpiece connected to a digital spirometer that records lung performance.

The test evaluates:

• Lung capacity

• Airflow obstruction

• Air trapping

• Gas exchange efficiency

It is widely used to diagnose obstructive and restrictive lung diseases and to monitor disease progression and response to treatment. The test is completely safe, painless, and non-invasive.

This test plays a critical role in:

• Diagnosing asthma, bronchitis, and emphysema

• Detecting early lung function decline

• Evaluating shortness of breath

• Monitoring chronic respiratory diseases

• Assessing lung damage due to smoking

• Pre-operative lung fitness evaluation

• Monitoring treatment response for respiratory conditions

At PrognoHealth, PFT tests are conducted using advanced computerized spirometry systems under expert supervision, ensuring accurate, reproducible, and reliable lung assessment.

Patient Preparation Instructions:

1. No fasting required, but avoid heavy meals before the test.

2. Avoid smoking 4–6 hours before testing.

3. Wear comfortable loose clothing.

4. Avoid intense physical activity before the test.

5. Inform your doctor about existing respiratory conditions and inhaler medications.

6. Pregnant women should inform the doctor before testing.
