Pulmonary Function

Your family doctor may order breathing tests or they may refer you to a Respirologist who may order testing.  Your doctor will submit requisitions for testing to occur.

Pulmonary Function tests are non-invasive tests that show how well the lungs are working. The tests measure lung volume, rates of flow, capacity and gas exchange.  The information from these tests can help diagnose and guide treatment for lung disorders.

Types of Pulmonary Function Tests:

  • Complete Pulmonary Function Test
  • Drop-in Spirometry
  • Bronchial Challenge test (Methacholine)
  • Arterial Blood Gas
  • Walking Oximetry
  • Overnight Oximetry
  • Cardiopulmonary Exercise Testing (VO2max)

At Providence Health Care Pulmonary Function testing is performed in labs at both St. Paul’s Hospital (SPH) and Mount Saint Josephs Hospital (MSJ). 

Respiratory Therapists use highly technical computerized equipment and physiological monitoring to perform breathing tests. Respiratory Therapists performing pulmonary function testing will guide you through the individual steps required for testing.  Our Pulmonary Function team is dedicated to ensuring patients achieve the most accurate test results in a respectful and caring manner.
