Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs work. This includes how well you’re able to breathe and how effective your lungs are able to bring oxygen to the rest of your body.
Why are these tests done?
- lung fibrosis
- bronchiectasis, which is a condition in which the airways in the lungs stretch and widen
- chronic bronchitis
- respiratory infections
- chronic obstructive pulmonary disease (COPD), which used to be called “emphysema”
What are the risks of taking pulmonary function tests?
A PFT can cause problems if:
- you’ve recently had a heart attack
- you’ve had recent eye surgery
- you’ve had recent chest surgery
- you’ve had recent abdominal surgery
- you have a severe respiratory infection
- you have heart disease
