Pulmonary Function and Bronchoprovocation Testing

Pulmonary Function Tests (PFTs)

Pulmonary Function Tests (PFTs) are breathing tests that can measure airflow in and out of lungs, lung volume or capacity, and lung’s ability to move oxygen into the blood. These tests are performed to make measurements of how your lungs and airways function. Results from pulmonary function tests enable your physician or health care provider to evaluate your breathing, make diagnosis, recommend treatment and follow your progress.

Your doctor may also schedule you for a Fractional Exhaled Nitric Oxide (FENO) test. This test will provide valuable information about airway wall inflammation.

Our staff will guide you with clear instructions during pulmonary function tests and encourage you to give your best effort. Please avoid smoking or eating a heavy meal before your scheduled breathing test. Our office will provide specific guidance if any inhaler medications need to be held prior to the test. Please feel free to ask questions before, during or after your test.

Bronchoprovocation Tests

A Bronchoprovocation Test is typically ordered by your physician to determine if you have reactive airways seen in conditions such as asthma. In general, you will inhale a nebulized solution to see if you develop symptoms of asthma or airflow obstruction measured by spirometry. The most commonly used bronchoprovocation test is the Methacholine Challenge Test.

The test takes about one hour to complete. Please be sure to bring a list of your current medications with you to your appointment. The following medications may interfere with your test results. Therefore, it is important that you stop taking them prior to your test for the amount of time recommended next to each medication.
