PULMONARY FUNCTION TEST

A Pulmonary Function Test (PFT) is a non-invasive diagnostic examination used to assess how well the lungs are functioning. The test measures lung volume, airflow, breathing capacity, and gas exchange efficiency, helping doctors evaluate respiratory health and diagnose various lung conditions.

PFT is commonly performed to detect, diagnose, and monitor respiratory disorders such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, bronchitis, and other breathing-related conditions. The test provides valuable information about lung performance and helps determine the effectiveness of ongoing treatment.

By measuring how much air a person can inhale and exhale and how efficiently oxygen moves into the bloodstream, Pulmonary Function Testing plays a vital role in maintaining respiratory health.

Benefits of the Test

• Evaluates overall lung function accurately.
• Helps diagnose asthma and COPD.
• Measures lung capacity and airflow.
• Assesses breathing difficulties and shortness of breath.
• Monitors progression of lung diseases.
• Evaluates treatment effectiveness.
• Supports pre-operative respiratory assessment.
• Non-invasive and safe procedure.

Why Doctors Recommend This Test

Doctors may recommend a Pulmonary Function Test for patients experiencing chronic cough, wheezing, shortness of breath, chest tightness, suspected asthma, COPD, smoking-related lung disease, occupational lung exposure, or unexplained breathing difficulties.

The examination helps determine the cause and severity of respiratory symptoms and guides appropriate treatment planning.

Preparation Before Test

• Avoid smoking before the test.
• Avoid heavy meals immediately before the examination.
• Wear loose and comfortable clothing.
• Inform your doctor about respiratory medications.
• Follow instructions regarding inhaler use before testing.
• Avoid strenuous exercise prior to the examination.

Normal Reporting Time

Most Pulmonary Function Test reports at Focus Diagnostics are available within 2–3 hours after completion of the test.

Who Should Take This Test?

This test may be recommended for:

• Individuals with chronic cough.
• Patients with asthma symptoms.
• People with COPD or emphysema.
• Individuals experiencing shortness of breath.
• Smokers and former smokers.
• Patients with occupational exposure to lung irritants.
• Individuals undergoing pre-operative evaluation.
• Patients requiring respiratory health assessment.

Detailed Information

Pulmonary Function Testing includes a series of breathing assessments that evaluate lung volumes, airflow rates, and gas exchange capabilities. The most commonly performed component is spirometry, which measures how much air can be inhaled and exhaled and how quickly air moves through the lungs.

The test helps diagnose obstructive lung diseases such as asthma and COPD, as well as restrictive lung disorders that limit lung expansion. It is also used to monitor disease progression and evaluate treatment response.

PFT is frequently recommended before major surgery to assess respiratory fitness and identify potential risks. The examination is safe, painless, and suitable for both adults and children capable of following breathing instructions.

At Focus Diagnostics, Pulmonary Function Testing is performed using advanced respiratory diagnostic equipment to provide accurate results and timely reporting for optimal patient care.
