Spirometry Testing: What Your Team Needs to Know
Are You Monitoring Lung Health Properly?
When your employees work around airborne hazards, protecting their respiratory health involves more than making sure they have the right personal protective equipment (PPE).
Respirators can help reduce exposure. Fit testing can help confirm that a respirator fits properly. But neither tells you how an employee's lung function is changing over time.
That's where spirometry testing comes in.
Spirometry is a pulmonary function test that measures how much air a person can move in and out of their lungs and how quickly they can exhale. In occupational health programs, it can help establish a baseline and monitor respiratory health over time. But even beyond compliance, monitoring lung health gives employers another way to protect the people behind the work.
Why Does Lung Health Matter at Work?
Some workplace hazards can affect the respiratory system, particularly when employees are repeatedly exposed to airborne particles or fibers. Consider an employee who has been working around a respiratory hazard for several years. A respirator may be part of their protection program, but employers also need a way to monitor whether their respiratory health remains stable.
That's one of the key reasons spirometry matters. Think of it as monitoring the body over time.
A baseline result gives you a point of comparison. Follow-up testing can show whether lung function has changed. If a meaningful change appears, it can prompt appropriate medical evaluation and a closer look at the employee's workplace exposures.
Spirometry vs. Respirator Fit Testing
These tests serve different purposes: Respirator fit testing determines whether a specific respirator properly fits the employee, while Spirometry testing measures aspects of the employee's lung function.
Both can have an important place in a comprehensive respiratory protection and occupational health program.
Spirometry isn't automatically required for every employee who works around dust or wears a respirator. Requirements depend on the workplace, type and level of exposure, applicable regulations, and recommendations from the appropriate healthcare professional.
Some of the workplace hazards where respiratory health monitoring may be particularly important include asbestos and respirable crystalline silica.
What Happens During a Spirometry Test?
For employees who have never had spirometry, the process may sound more complicated than it actually is. The test itself is relatively quick.
- Take a Deep Breath - The employee will be asked to inhale as deeply as reasonably possible. The goal is to fill the lungs with as much air as possible.
- Seal Around the Mouthpiece - The employee places their mouth around the spirometry mouthpiece to create a proper seal.
- Blow Out Forcefully - This is the part that can feel unusual. After taking a deep breath, the employee is instructed to forcefully exhale as completely and quickly as possible through the mouthpiece. The technician may encourage the employee to keep going and push out as much air as possible. It sounds simple—but getting a good test requires effort and proper technique.
- Repeat the Test - The maneuver may be repeated to obtain reliable and consistent measurements. A trained technician guides the employee through the process and provides instructions throughout the test.
- Review the Results - The measurements are then evaluated using appropriate reference values and the requirements of the applicable occupational health program.
Results are not simply classified as “good” or “bad.” They're interpreted in context, using appropriate reference values and considering the employee's history and circumstances. An abnormal result does not automatically mean an employee has an occupational disease or that workplace exposure caused the result.
Instead, it may indicate that additional evaluation is appropriate. That's why monitoring results over time can be so valuable.
A single test gives you a snapshot. Repeated testing can help show the bigger picture.
Testing frequency depends on the applicable OSHA standard, workplace exposure, employee circumstances, and recommendations from the appropriate healthcare professional. There is no one-size-fits-all schedule.
For example, OSHA's covered silica medical surveillance requirements call for periodic examinations at least every three years, or more frequently if recommended by the physician or other licensed healthcare professional. Covered employees under the general-industry asbestos standard are offered periodic medical examinations annually.
For employers conducting voluntary respiratory health monitoring, the appropriate schedule should be determined based on the organization's hazards and occupational health program.
Choosing a Spirometry Testing Provider
Your testing provider should be more than someone who simply shows up, performs the test, and leaves. Workplace health programs don't always go exactly according to plan. Crews get reassigned. Production schedules change. Projects move. Employees have questions.
- Your provider needs to be able to work with you—not just work for you. When evaluating a spirometry testing provider, consider:
- Flexibility - Can the provider accommodate reasonable scheduling changes when your operations shift?
- Support - Can you get answers when you have questions about the testing process, frequency, or next steps?
- Qualified Personnel - Are testing personnel appropriately trained and qualified for the testing being performed?
- Occupational Health Experience - Does the provider understand that workplace testing needs to fit into your safety program without unnecessarily disrupting your operation?
At Anadyne, we understand that protecting employees and keeping your operation moving aren't competing priorities. Our goal is to provide occupational health services that support your safety program while minimizing unnecessary disruption to your production and profitability.
Don't Wait Until There's a Problem to Start Monitoring
Respiratory protection is about more than PPE. It's about understanding the hazards your employees face, providing appropriate protection, and monitoring their health when required or appropriate.
Spirometry testing gives employers a way to monitor lung function over time and can be an important component of an occupational respiratory health program. If your team works around silica, asbestos, or other respiratory hazards, let's talk about your current program.
