Pulmonary Function Tests
Pulmonary function tests (PFTs) are a group of breathing tests. They can show how well your lungs are working. PFTs may measure:
- How much air you can blow out
- How much air your lungs can hold at different times during the breathing cycle
- How fast you are blowing air out
- How well gas is being transferred from your lungs into your blood
