In brief: PFT's

are tests that look at your lung function.
They are used to tell if you have obstructive disease by looking at how much air you can blow out; they can tell if you have a restrictive disease by looking at your lung volumes; and they can tell how well you are able to exchange oxygen between your alveoli (air sacs) and capillaries by doing a diffusion test.

In brief: Pulmonary function

Pulmonary function testing generally requires a person to sit in a booth and breathe through a mouthpiece.
A machine analyzes the flow and volume of air moving trough the lungs. The procedure is benign and not painful.
