Pulmonary tests

The Pulmonary Diagnostic Lab assists in the diagnosis and care of patients with breathing problems. Through the use of sophisticated monitoring equipment, the tests we do will help your doctor determine if you have a breathing disorder, if your current medications are appropriate for you and make appropriate changes in your current medical treatment.

Tests are performed by respiratory care practitioners with credentials in pulmonary function testing. Test results are interpreted by a doctor specializing in pulmonary medicine.

Pulmonary tests conducted at the lab include:

  • pulmonary function studies
  • arterial blood gases
  • cardiopulmonary stress test (either treadmill or ergometric)
  • exercise challenge test (pediatric)
  • Methacholine challenge — The methacholine challenge aids in the diagnosis of asthma or reactive airways. You will be asked to breathe into a machine after inhaling varying doses of a medication. your responses to the medication will be evaluated. This procedure may take as long as two hours. 
  • oximetry (resting, exercise, titrating 02 with exercise )
  • spirometry screening (occupational or health fairs)

Your doctor will give you instructions before you come to the hospital for a pulmonary test. Be sure to follow these instructions to help ensure the accuracy of the test.
