A spirometry breathing test shows how well you can move air in and out of your lungs. Testing may be performed on workers who perform jobs that may cause exposure to possible lung hazards, are physically demanding, or require wearing a respirator. The test shows how well you can move air in and out of your lungs. Spirometry testing is required for some workers by OSHA standards.

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 wearing a respirator or working in an environment where there are potential hazardous exposures.

The information gained from respiratory health surveillance, including medical evaluation and pulmonary function testing, 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 pulmonary function test. OccumedKe 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 any of these tests (or a combination of them) to examine results over time to diagnose a worsening condition or a need for work restriction or medical treatment.

It’s important to understand that OSHA requires pulmonary function testing only in the medical surveillance provisions of standards related to specific substances, such as asbestos, cotton dust, benzene, formaldehyde and, more recently, silica and beryllium
