The Importance of Regular Pulmonary Function Test for Certain Occupations

To understand why different occupations should get their pulmonary function test done.
To understand why different occupations should get their pulmonary function test done.

A pulmonary function test (PFT) is a list of tests that help in the examination of lungs. Pulmonary function tests inspect different areas of lung health, along with the potential for air to move inside and outside of the lungs. It is an important test as it helps us to understand the health of our lungs. There are a wide variety of PFTs that are done, each with a different purpose.

Why Is a Pulmonary Function Test Important?

Pulmonary function tests give us a lot of important information about the health and performance of the lungs. They also help in the identification, monitoring, and management of different lung conditions. 

PFT’s help to find out specific lung related disorders or diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and different lung problems and diseases. This information helps in determining whether a situation is stable, improving, or getting even worse. PFTs are also of the utmost importance, especially during lung surgeries, to understand the patient’s lung function and the level of risk involved. 

Types of Pulmonary Function Test

There are several types of PFTs, each PFT focuses on a different feature of the lung function. Some of them are as follow:

  • Spirometry is the most common type of test that finds out the amount of air a person can inhale and exhale at a certain time. 

  • A lung volume test helps us evaluate the variety of lung volumes to calculate the all over lung capacity (TCL) and other lung functioning levels.

  • Diffusion capacity tests help us see how effectively the lungs exchange oxygen with the blood.

  • bronchoprovocation test determines how reactive the airways are and is commonly used to find out about asthma 

Occupations That Are More Prone to Get Lung Disorder Thus Need Regular PF Tests

In many occupations, people are at high risk of exposure to respiratory unsafe situations. This makes it of vital importance for them to frequently get their pulmonary function tests done. The major exposure happens to dust, fumes, chemicals, or other floating particles that can harmfully affect the health of the lungs. Some major occupations that should consider regularly getting PFTs done are:

Miners come in close contact with dust and other floating particles like silica, which lead to respiratory problems like pneumoconiosis (black lung disease) and silicosis.

Workers working around the site come in contact with dust, asbestos, and other dangerous materials, which increases the risk of lung problems such as asbestosis and COPD.

Workers in manufacturing and industries certainly come into contact with chemicals while wielding or metalworking, due to which they inhale harmful and chemical fumes and particles.

Farmers and other workers near the farm get in contact with dust, pesticides, and mold, which leads to respiratory problems.

Firefighters come in contact with smoke, ash, and toxic and chemical fumes from burning materials, which increases the risk of lung problems and lung diseases.

Individuals in the oil and gas industry are exposed to dangerous gases, chemicals, and matter particles during drilling, refining, and transportation.

Workers in this occupation come into close contact with dust, mold, and other floating pollutants that may affect their overall lung health.

Individuals in this industry and manufacturing come in close contact with dust as well as fibers which may develop critical conditions like byssinosis, i.e., brown lungs. 

Workers related to this occupation are exposed to metal fumes and gases, which can lead to respiratory issues.

Individuals in this industry are exposed to asbestos, paint fumes, and other harmful materials, which lead to a risk of lung-related health issues.

Major symptoms that are seen in people who need a PFT are coughing, chest pain, wheezing, etc. Hence finding out the main causes of these symptoms, doctors can identify and manage any problems related to lung diseases in order to help workers maintain good overall health and well-being.  


The pulmonary function tests help in finding out various respiratory problems, the level at which the problem is being caused, how efficiently the treatment is working for the patient, etc. 

Pulmonary function tests play a vital role in occupational health by identifying respiratory hazards, monitoring lung function, detecting early signs of lung damage, and guiding preventive interventions to protect workers from occupational lung diseases. 

Pulmonary function tests (PFTs) are a group of tests that measure how well the lungs are functioning. These tests provide valuable information about lung capacity, airflow, and gas exchange, which can help diagnose and monitor a variety of respiratory conditions.

Pulmonary function tests (PFTs) are commonly used to assess lung function and diagnose respiratory conditions. People who should get their Pulmonary function test done are individuals with symptoms of wheezing, chronic cough, chest tightness, etc. Individuals who smoke and workers who are exposed to occupational hazards known to affect respiratory health, such as dust, chemicals, fumes, particulate matter, etc., should get themselves tested.
