Respiratory Care

Pulmonary function testing at the Washington University Asthma and Allergy Center at Barnes-Jewish West County Hospital is equipped to treat patients with issues that affect the lungs and breathing.

The center is staffed by registered pulmonary technicians using American Thoracic Standards (ATS) testing guidelines. Tests are interpreted by board certified pulmonologists.  

Early detection and treatment can decrease the severity of disease progression. Many patients are referred by their physician for the following:

  • Asthma
  • Bronchitis
  • Lung cancer
  • Acute and chronic respiratory failure
  • Pulmonary hypertension
  • Chronic obstructive pulmonary disease (COPD)
  • Lung infections

Other referrals for testing could include:

  • Lung function evaluation prior to surgery.
  • To identify oxygen therapy needs.
  • Muscle strength.
  • Evaluate the effects of environmental/occupational exposure.
  • Check for asthma with a chemical or exercise challenge.
  • Check effectiveness of patient's therapy or to obtain a baseline prior to treatment.

WHAT IS A PULMONARY FUNCTION TEST

Pulmonary function tests are a group of tests that evaluate how well your lungs work. These 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 severity of lung problems, and check to see how well treatment for a lung disease is working.

WHAT TO EXPECT DURING A PULMONARY FUNCTION TEST

After your arrival, you will will meet with a registered respiratory therapist and a typical evaluation will include:

  • Answering breathing related questions.
  • Analysis of your breathing patterns, which may include normal breathing, panting, brief breath hold, deep breaths, and soft or forceful blowing.

Your pulmonary function test results will be sent to your referring physician.

HOW TO PREPARE FOR A PULMONARY FUNCTION TEST

  • Wear loose-fitting clothing as you may need to walk during a portion of the test.
  • Consult with your physician about specific instruction for bronchodilators or inhaler medications.
  • Do not eat a heavy meal before the test. 
  • If you are a smoker, you should not smoke for four to six hours prior to your appointment. If you smoke, quitting may be the single most important thing you can do to improve your health. The following resources may help you reach this goal:
