Pulmonary Function Test Q & A
Why would I need a pulmonary function test?
There are many lung disorders that can affect how well you breathe. The first order of business is identifying the problem and determining to what degree the condition is affecting the function of your lungs.
Pulmonary disorders can compromise the function of your lungs in one of two ways:
This means that something is blocking the ability of your airways to get air in and out of your lungs.
This problem occurs when the tissues in your lungs don’t expand properly, leaving you with decreased lung capacity.
There are a myriad of problems that can lead to these two issues, including:
- Asthma, allergy-induced asthma, and allergies
- Respiratory infections such as pneumonia and bronchitis
- Pulmonary embolism
- Pulmonary fibrosis
- Lung cancer
- Chest injuries
Even a minor problem with shortness of breath is cause for concern and a simple pulmonary function test is the best way to root out the problem.
What is a pulmonary function test?
The pulmonary function testing at Texas Pediatric Specialties and Family Sleep Center is designed to measure several important aspects of lung function, including:
- The volume of your lungs
- The capacity of your lungs
- Rate of flow
- Gas exchange
The primary tool for testing your lungs is spirometry. To perform this test, you breathe into a mouthpiece called a spirometer several times so that your pulmonologist can determine the rate of flow in your lungs and your lung size. This test may take place in an airtight room so that nothing interferes with your results.
Other lung tests might include a FeNO test, which measures how much nitric oxide you exhale, and an impulse oscillometry, which measures lung impedance.
Do I need to prepare for a pulmonary function test?
A pulmonary function test is completely noninvasive and doesn’t require much effort on your part. There are a few steps your pulmonologist may ask you to take to prepare in advance, such as:
- Stop use of any medications that affect your breathing
- Cease smoking or drinking for several hours before the test
- Delay any exercise until after your test
- Avoid a large meal beforehand
Rest assured, one of the team members makes sure you have complete instructions before you come in for your pulmonary function test.
