Pulmonary Function Test (PFT)
About the service
This non-invasive, 30 minute test is a series of tests that measure a patient’s breathing and once completed and combined will give us a baseline of total lung capacity. This test helps our providers determine the next step in diagnosing and treating our patients. This test is normally ordered first as it gives us an established baseline of our patient’s lung function and is normally done annually to observe any worsening. A few lung disorders that PFTs will help diagnosis include: COPD, emphysema, restrictive lung disease, and to rule-out asthma. There are certain instructions to follow prior to the PFT, see our FAQs for more information.
What to expect
PFTs are safe and noninvasive, and they typically take only about 30-60 minutes to complete. There’s no reason to be nervous going into a PFT– they’re not scary, and they can provide valuable information that leads your doctor toward a diagnosis and a treatment plan.
Our wonderful staff will explain what to do for each part of the testing process, and– mostly– all you’ll have to do is breathe.
First visit: The details of your visit may vary based on your specific symptoms, overall health and care preferences. In general, though, here a brief overview of what you can expect at your pulmonologist appointment.
- Detailed questions regarding your current health and medical history, including smoking habits, previous surgeries, recent vaccinations, major health conditions and family medical history
- A review of basic health characteristics, including height, weight, temperature, blood pressure and oxygen levels
- A physical exam, which may involve checking for signs of low oxygen levels, swelling and reduced blood circulation
- Diagnostic testing in accordance with your symptoms—this may include a spirometry test, chest X-ray, CT scan or exercise oximetry test
It’s also a good idea to bring these items to your pulmonology appointment or send them electronically, if applicable:
- Pulmonary function test results
- Results from X-rays and other imaging tests
- Bloodwork results
- A list of any medications and supplements you are taking, along with the dosage and prescribing physician
In addition, consider making a list of any questions you would like to ask your pulmonologist during your visit.
Second visit: During your second visit, the provider will go over all tests that were ordered during your initial visit and discuss a treatment plan with you.
Ongoing: The details of your ongoing visits will depend on your treatment plan and health condition.
