Pulmonary Testing Q & A

What is pulmonary function testing?

Pulmonary function testing (PFT) is designed to evaluate how well the lungs are working. Several types of PFTs are available depending on what type of issue is being tested or measured. Some tests measure how well the lungs work under different conditions like physical exercise or when at rest while others can measure the capacity of the lungs (how much air they can hold) or how much air the lungs can exhale. PFTs are commonly used in the diagnosis and management of some pulmonary and heart-related issues, including asthma, chronic obstructive pulmonary disease, asbestosis, congestive heart failure (CHF) and other issues that cause shortness of breath (also called dyspnea).

What happens during a pulmonary function test?

That depends on what type of test is being performed. Some PFTs use a special device called a spirometer that measures the amount of air that’s exhaled. During this test, a soft clip is placed over the nose to avoid air “leakage” during forced exhalation from the mouth. The device measures the amount of air expelled over a certain period of time, including during forced exhalations (when the patient expels as much air as possible).

Some patients may be asked to complete the test more than once to obtain the most accurate readings. Other types of lung function tests are performed while the patient is using a treadmill or exercise bike to evaluate lungs performance during physical exertion. These tests are sometimes referred to as cardiopulmonary exercise tests or CPETs.

When are lung function tests performed?

Testing can be used to assess an array of breathing issues, including lung capacity, the rate at which that air can be expelled, and how much air the lungs expel in a single breath, in addition to measuring lung performance during exercise. The tests are frequently performed during treatment for heart disease or to evaluate a patient prior to or after heart surgery. And of course, they’re also used to diagnose, assess and manage diseases affecting the lungs.

What is a home sleep study?

In a home sleep study, you wear a tiny device called an oximeter, which is clipped on your finger, and an oxygen sensor, which is placed under your nose for the entire night. This device measures and records your blood oxygen and pulse while you’re asleep. Dr. Facemyer then studies the recorded information for signs of a problem. Often, a home sleep study can help diagnose sleep apnea. Sometimes additional sleep studies may need to be held in a sleep lab to further treat or assess the problem.
