Spirometry in occupational health

The primary role of spirometry in occupational health is to identify workers who should have secondary testing or examinations by a pulmonary medical professional. In some regions and industries, spirometry is mandated due to regulatory compliance and the exposures to the workforce.

When any industry, corporation, or company uses spirometry as a proactive occupational health tool to monitor respiratory function, not only does it place a focus on employee's well-being, but it can also serve to discover root issues causing these respiratory conditions.

Occupational health spirometry testing is an exceptional, noninvasive, and highly effective method of monitoring the lung capacity and wellness of employees.

Frequently asked questions


What do I need to start spirometry testing in my clinic?

To get started, you'll need the following:

  • Spirometer
  • Mouthpieces
  • Nose clips
  • 3-liter calibration syringe with adapter (Required by NIOSH. View guidelines here.)
  • Filter & adapter (It is important to note that each facility has their own requirements. There are no current known guidelines on the requirements. Please check your organization's policy on filter use when performing spirometry.)

Do I need to calibrate my EasyOne device when testing in an occupational health setting?

Yes, when performing spirometry testing in an occupational health setting, NIOSH/OSHA requires the spirometer be checked using a 3-liter calibration syringe each day testing is performed. A calibration check (cal-check) is not to be confused with calibration. A cal-check simply validates that the device is within calibration limits. Unlike calibration, a cal-check does not adjust the calibration values.

You can view instructional videos on how to perform a calibration check on ndd devices below:

Do the EasyOne products meet OSHA/NIOSH/SSA standards?

Yes, ndd products meet all testing/reporting standards. For a more detailed information, visit the NIOSH website here. 


Do I need to use filters?

There are no current known guidelines on the use of filters when performing spirometry. Each facility has their own requirements. Please check your organization's policy on filter use when performing spirometry. 


How do I use the filters with the EasyOne products?

Assembling the filter and adapter components is simple and easy. Read our how to blog here, and learn how to connect a filter to the EasyOne products. You can also view our video library.
