Spirometry *

Pulmonary function testing, as part of a respiratory protection program, helps you manage and reduce work-related lung injuries from inhaled respirable hazardous exposures.

Protect your employees and avoid an OSHA penalty. Pulmonary function tests are an essential component of your respiratory protection program because they measure an employee’s lung function. When performed on a new hire, a pulmonary function test can identify employees who may not be suited to wear a respirator or work in an environment where there are potential hazardous exposures.

The information gained from respiratory health surveillance may lead to detection of early lung disease. Detecting lung disease early allows for earlier access to management and treatment. Pulmonary function tests truly are a safety net for employees.

Spirometry is the most common employment related pulmonary function test. Aculas uses spirometry to measure:

  • Air volume breathed out, or forced vital capacity (FVC)

  • Air volume expelled in one second, or forced expiratory volume in one second (FEV1) and

  • The relationship between the two (the FEV1/FVC ratio)

Clinicians can use these tests to examine results over time to diagnose a worsening condition, a need for work restriction or medical treatment.

To be OSHA compliant, pulmonary function tests must be performed by technicians who have been certified by completing a spirometry training course approved by the National Institute of Occupational Safety and Health (NIOSH).
