A Pulmonary Function test is a breathing test that measures how well your lungs are working. There are many reasons why your physician may need to have you perform a Pulmonary Function test. The most common of these are:
- shortness of breath
You may need to have Pulmonary Function tests performed regularly if you have been diagnosed with a lung disease like:
- pulmonary fibrosis
You may also need to have Pulmonary Function tests performed in order to obtain a baseline for:
- radiation therapy
Some tests can be performed in your physician’s office but many will need to be performed in a Pulmonary Function Lab by trained technicians. Your physician will order the tests that he believes will be most helpful in diagnosing or monitoring your condition.
In order to perform any Pulmonary Function Test you will need to breathe in very specific ways and at very specific times. The technician performing your tests should be able to explain how and when you are supposed to breathe. The ways in which you will need to breathe may often seem peculiar but there are good reasons for every breathing maneuver you will be asked to perform.
Most people are able to perform these breathing maneuvers either right away or with some practice. Occasionally however, some individuals have difficulty performing these tests. There are several relatively common reasons that this can happen.
