 About Pulmonary Function Test / PFT Test


What is a Pulmonary Function Test?

A pulmonary function test measures the power and efficiency of the lungs. The equipment may look complicated, but the test is totally needle-free, pain-free, and non-invasive.

The nose has to be plugged in order to get an accurate reading.

Then the patient blows into a mouthpiece which is attached to a tube and a computer. The computer will measure the amount of air that the lungs expel, as well as how much oxygen is present in the air.

Why do I need a Pulmonary Function Test?

A pulmonary function test is given for several reasons. They can be recommended by a pulmonologist, or lung specialist, but you may also be directed to get one by your primary care provider, cardiologist, or even another specialist. The lungs and the heart are very closely related. Heart problems, peripheral circulatory problems, and lung problems often cause similar symptoms. 

The most common reasons our cardiovascular specialists perform this lung test are:

  • to find the cause of shortness of breath. The lungs fill blood with oxygen, and the heart pumps the oxygen-rich blood to every cell in the body through tubes called arteries and veins. When something in this system goes wrong, it often causes a physical sensation called "shortness of breath." If your breathing has ever been so labored that you had trouble speaking, you've experienced shortness of breath. (Even high-intensity exercise shouldn't take away your ability to speak.) In order to treat the underlying condition, your cardiologist or vascular specialist needs to identify where the problem lies: the heart, the lungs, or the arteries and veins. Testing your lung power will help him or her figure it out.

  • to check the effectiveness of lung or heart disease treatment. Perhaps the cause of your shortness of breath has already been identified, and now you're being treated for a specific condition. Or, maybe you're being treated for a completely different condition with a medication that's known to cause side effects in the lungs. In such cases, your doctor will likely want to test your lungs regularly to check the progress of your treatment. 

  • to ensure you're strong enough to have surgery. Your vascular surgeon or other doctor will need to make sure your lungs are strong enough to withstand the stress of general anesthesia. If you're having surgery on the lungs or heart, your lungs must be strong enough to withstand the stress and trauma of major surgery. 

  • to clear you for work in certain professions. If you need to wear a respirator for work, you may have to prove that your lungs are up to the challenge. We usually provide such testing under union insurance plans. 

What are the Risks of Pulmonary Function Tests?

This test does not pose any health risks. No needles, harmful rays, or drugs are used. You will not be asked to exercise. In fact, at-home versions of this test are available at many drugstores and medical supply stores.
