Breathing test: The pulmonary function test measures how well air moves in and out of the lungs and what you lung capacity is. Basically you blow into a machine. You may be asked to use an inhaler and the test may be repeated to see if there is any change in the measurements. The pulmonary function test is an important part of an asthma or COPD evaluation and is used to follow your progress to treatment.

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.

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.

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.

Checks lung function: Pfts check numerous areas of lung capacity, flow rates, etc. And are useful in treating/diagnosing emphysema, copd, restrictive ariway diseases, asthma, and understanding lung capabilites prior to surgery. This would be common in smokers, elderly, or in patients with lung diseases like cystic fibrosis. Pfts are easy and done in a lab or pulmonary specialist's facility.

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.
