Pulmonary Function Testing

Lung function tests (also called pulmonary function tests, or PFTs) check how well your lungs work. The tests determine how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs put oxygen into and remove carbon dioxide from your blood. The tests can diagnose lung diseases, measure the severity of lung problems, and check to see how well treatment for a lung disease is working.


Spirometry is the most commonly done lung function test. It measures how much and how quickly you can move air out of your lungs. For this test, you breathe into a mouthpiece attached to a recording device (spirometer). The information collected by the spirometer may be printed out on a chart called a spirogram.

Occupational Testing

When exposed to contaminants in the workplace, the employee’s lungs are directly affected impacting the health of their lungs. When left unchecked, this exposure can cause irreversible damage to the health of lungs. Spirometry can be utilized when implementing the Health Surveillance of the employees who wear respiratory protective equipment which is mandatory as per the Government of Alberta and consistent with the Alberta Occupational Health and Safety Code.
