Pulmonary Function Test

A Pulmonary Function test is a breathing test that shows the presence and extent of lung abnormalities. It is also used to evaluate the need for inhalers and the effects of medication on the lungs.

This test is ordered for patients who have symptoms or conditions such as:

• Asthma
• Chronic bronchitis
• Emphysema
• Pulmonary fibrosis
• Shortness of breath
• Persistent cough
• Wheezing

What you should know

Do not take Serevent or Advair for 12 hours before your test.

Do not take Ventolin, Atrovent or Bricanyl for four hours before your test.

Please allow 40 minutes for this test.

The Respiratory Therapist performing your exam will instruct you in a series of breathing tests. You will be seated in front of the machine that measures your lung function. You will be asked to hold a sterile mouthpiece between your teeth while performing the tests. In some cases we will give you an inhaler with Ventolin during the test.
