Question 1

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

Accepted Answer

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.

Question 2

what does it mean that my chg fef2575=22% on my pulmonary function test?

Accepted Answer

Possible obstruction: This particular test can detect a very early obstruction to the airflow (seen in diseases such as asthma/emphysema etc...)

However there are people with abnormal FEF 25-75 with minimal respiratory symptoms.

Question 3

what does the letter "f" from quality report on my pulmonary function test mean?

Accepted Answer

Can only guess: That the quality was fair likely meaning that your efforts were not sufficient in performing the test.

Question 4

what is involved in typical pulmonary function test?

Accepted Answer

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.

Question 5

what can trigger an inaccurate pulmonary function test?

Accepted Answer

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

Question 6

what could have caused me to fail my pulmonary function test?

Accepted Answer

Several causes: Abnormal values on lung function test can be due to several reasons:
if shows obstruction: asthma or copd
if suggests restriction: overweight, abnormal chest wall, alveolar disease
poor technique (it's not easy to perform)
a conversation with your doctor will help clear it up.

Question 7

i have to get a pulmonary function test. what does this entail?

Accepted Answer

Blowing: You have to blow into a tube. You will be given specific instructions by the therapist performing the test. No injections, no anesthesia. You might be given a medication to inhaler. You might have to sit in a closed glass box.

Question 8

what is the definition or description of: pulmonary function test?

Accepted Answer

Lung function tests: 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.

Question 9

my daughter's pulmonary function test showed moderate obstruction, what does this mean?

Accepted Answer

Restricted airway: Her airway is narrow or partially blocked by something. The next step is to find out why. Does she have asthma? Is it a congenital defect? These are questions to ask your doctor or pulmonologist.

Question 10

could the breathing exercises, performed during pulmonary function test, be done routinely?

Accepted Answer

Yes, no benifit : There is no benefit to do them to increase lung function. The best way is to build endurance is  through a structured physical therapy program.  Nothing can really increase lung capacity either. This is a matter of conditioning. You can do the exercise but no real gain. If you want to measure during exercise then a cardiopulmonary stress test is better. This is a dynamic test on a bike.
