Pulmonary Function Test (Overview)

Pulmonary function tests is a term used to describe a group of tests done to determine lung function. Spirometry measures the amount of air that can be taken in as well as the flow rate of forcefully exhaled air . A graph is generated and can be used to determine lung function. Likewise lung volumes and diffusing capacity determine the capacity as well as the oxygen exchange function.

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. ...Read more

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. ...Read more

What happens during a pulmonary function test?

What happens during a pulmonary function test?

Breathing test: Pulmonary function test (pfts) are non-invasive breathing studies done with a computer. You breathe into it according to the direction of the technician and it measures the volume of air and forces during breathing. Often then you breath in a medicine that relieves airway spasm (bronchodilator) to measure any changes resulting. Another part of the test measures gas exchange at the alveolar level. ...Read more

What is invovled in a pulmonary function test?

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. ...Read more

What can trigger an inaccurate pulmonary function test?

PFT: This test can be highly variable. The quality of the test can depend on several things. The patient performing the test has to really give it a good effort. Many times this is also dependent on the person administering the test, who must be a good instructor. Also the equipment must be calibrated, and functioning well, no air leaks and also the type of equipment may allow for some variability ...Read more

Can i tell me how i can pass a pulmonary function test?

Can't be done: You can study to pass an exam, try to cheat to pass a drug test (it probably will not work), but you can't do anything to pass a pulmonary function test. It's a measure of your body, and it's as impossible to prepare for it as it is to prepare to have your height measured. ...Read more

What is a good dclo number on a pulmonary function test?

100% of predicted: A good one would be one as close to normal as possible. Too low a dlco/va means that there is likely an air-transfer blockage. Too high may point to asthma. ...Read more
