PFT stands for Pulmonary Function Test.

What does PFT mean?

breathing tests that measure how well the lungs work

PFT stands for pulmonary function test, a group of breathing tests that measure how well the lungs take in air, move it, and transfer oxygen to the blood. The tests record how much air the lungs can hold, how fast air can be breathed out, and how well gas passes into the blood. Spirometry is the most common part. PFTs help diagnose and monitor conditions such as asthma and chronic obstructive pulmonary disease, and they separate obstructive patterns from restrictive ones.

When is PFT used?

PFTs are ordered in respiratory clinics, primary care, and before some surgeries to assess lung health.
