Pulmonary Function Tests (PFTs) are a group of non-invasive diagnostic tests designed to evaluate how well your lungs are functioning.These tests assess different aspects of your lung capacity and effectiveness, aiding healthcare experts in diagnosing respiratory conditions like asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis and more. PFTs also helps in assessing the severity of lung diseases, monitoring their progression over time and response to the treatment.
Test NamePulmonary Function Test (PFT)
Preparations RequiredNo specific preparation is required for PFT Test
Report Time6 Hours
Pulmonary Function Test Procedure
During a PFT, you'll be asked to perform a series of breathing maneuvers while connected to specialized equipment. The most common tests include spirometry which measures how much air you can inhale and exhale and plethysmography, which assesses the amount of air in your lungs and how well your lungs expand and contract.
Before the test, you may be instructed to avoid certain medications or activities that could interfere with the results. During the procedure, you'll typically sit in a comfortable chair or booth and wear a nose clip to ensure that air only passes through your mouth. You'll then be asked to breathe in and out forcefully or steadily, following the technician's instructions.
The process is typically fast and painless, taking between 30 to 60 minutes based on the tests being done.

When is Pulmonary Function Test Performed?
Pulmonary Function Tests may be recommended for various reasons:
Diagnosis: If you're experiencing symptoms such as shortness of breath, chronic cough, wheezing, or chest tightness, your doctor may order a Lung function test(PFT) to help diagnose the underlying cause.
Monitoring: If you've already been diagnosed with a lung condition, regular Pulmonary Function Tests can help monitor your lung function and track the progression of the disease and response to the treatment. This is particularly important for conditions like asthma and COPD, which can worsen over time.
Pre-Surgery Evaluation: Before undergoing certain surgeries, especially those involving the chest or lungs, your doctor may perform PFTs to assess your lung function and determine if you're at increased risk of complications during anesthesia and recovery.

Pulmonary Function Test Results & Normal Levels
Normal Pulmonary function test (PFT) results may differ slightly based on age, gender, height, and ethnicity. Here are the normal ranges for some common parameters:
Forced Vital Capacity (FVC): This measures the total amount of air you can forcefully exhale after taking a deep breath. Normal FVC values typically range from 80% to 120% of the predicted value based on factors such as age, sex, height and ethnicity.
Forced Expiratory Volume in One Second (FEV1): FEV1 measures how much air you can exhale forcefully in one second. Typically, normal values range from 80% to 120% of the predicted value.
FEV1/FVC Ratio: This ratio compares the amount of air you can exhale in one second to the total amount of air you can exhale. A normal FEV1/FVC ratio is typically greater than 70% to 75%.
Peak Expiratory Flow Rate (PEFR): PEFR measures how fast you can breathe out air. The normal values depend on factors like age, gender, and height, usually falling between 80% and 120% of the expected value.
Total Lung Capacity (TLC): This measures the total volume of air in your lungs at the end of a maximal inhalation. Normal TLC values typically range from 80% to 120% of the predicted value.

A Pulmonary Fuction Test can diagnose various lung conditions such as asthma, COPD, pulmonary fibrosis and lung function abnormalities.
Individuals experiencing respiratory symptoms, smokers, those with known lung conditions, and candidates for certain surgeries may need a PFT.
A PFT is generally not painful, involving only breathing maneuvers into a mouthpiece connected to equipment.
Yes, PFT can detect lung damage by assessing lung function parameters like FVC, FEV1 and DLCO.
Normal lung capacity varies with age, but on average it ranges from about 4 to 6 liters for adults.
Normal PFT results include an FEV1/FVC ratio greater than 70-75% and values within 80-120% of predicted for other parameters.
