Pulmonary Function Test (PFT)

What is a Pulmonary Function Test?

A Pulmonary Function Test (PFT) is a medical examination used to evaluate how well the lungs are working. This test measures a person’s breathing capacity and identifies potential airway obstructions. Playing a crucial role in the diagnosis and management of respiratory diseases, it is especially mandatory for employees working in hazardous environments as part of their pre-employment health report. At İZKA OSGB, which provides professional occupational health and safety services in İzmir, we perform this test quickly and accurately.

Why is the Pulmonary Function Test Done?

This test is performed to assess lung health and is essential in the following cases:

• Diagnosis and monitoring of respiratory diseases such as asthma and COPD (Chronic Obstructive Pulmonary Disease)
• Evaluation of lung function in smokers
• Monitoring of other respiratory conditions that cause airway constriction
• As part of the pre-employment health report to evaluate lung health
• Routine checks for workers exposed to chemicals or dusty environments

The test is vital both for early diagnosis of respiratory illnesses and for maintaining control over existing conditions.

What Does the Pulmonary Function Test Measure?

Using specific devices, the test measures the following lung functions:

• FVC (Forced Vital Capacity): The amount of air a person can inhale into the lungs
• FEV1 (Forced Expiratory Volume in 1 second): The volume of air exhaled in the first second after a deep breath
• FEV1/FVC ratio: Indicates the flow of air through the lungs and detects airway obstructions

These values are especially important for hazardous and highly hazardous jobs, where such measurements are required in the health reports. Any airway issues can be detected early through this test.

How is the Pulmonary Function Test Performed?

A trained medical professional performs the test using a spirometry device. The patient is asked to take a deep breath and exhale forcefully into the device’s mouthpiece. The process is repeated a few times for accuracy, and results are obtained instantly. At İZKA OSGB, we carry out this test with precision for both pre-employment and periodic workplace health check-ups.

When Should the Pulmonary Function Test Be Done?

This test should be performed in the following situations:

• Complaints of shortness of breath or wheezing
• Chronic cough or smoking history
• Follow-up of existing lung diseases
• Workers in dusty or chemically hazardous environments
• As a mandatory check for those employed in hazardous and highly hazardous jobs

Routine testing helps protect employees’ lung health and ensures a safer workplace.

How to Interpret the Pulmonary Function Test Results?

Results are evaluated based on lung capacity and airway condition. For instance:

• A low FEV1/FVC ratio may indicate airway obstruction
• A low FVC may suggest reduced lung capacity

These results help the workplace physician create appropriate treatment or monitoring plans. The test is crucial for employees with respiratory conditions during the pre-employment health report process.

Where is the Pulmonary Function Test Performed?

The test is administered by Occupational Health and Safety Units (OSGB) as part of workplace health screenings and pre-employment health evaluations.
