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.

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.

PFT...: Pulmonary function tests are tests that measure your respiratory functioning. They will show if you have obstructive or restrictive lung disease as well as give information about the size of your lungs and how gases (oxygen, carbon dioxide) are exchanged. It will also show if the disease present is reversible with medicines, like bronchodilators. They are administered by a respiratory therapist.

Test for asthma: It involves blowing into a tube which is connected to a computer. It measures a number of variables of airflow. Often, after getting a baseline, we give the patient an asthma medication called "albuterol, " and repeat the test. The results are used to diagnose asthma and emphysema, among other diseases.

What's the question?: As much as we'd like to, nobody here can advise you without our knowing what's troubling you, what your symptoms and signs are, and what you've been told. Pulmonary function tests are of limited value even in arriving at a clinical diagnosis, let alone as a guide to treatment.
