Question 1

what does it mean when on a pulmonary function test you have normal spirometry but also hyperinflation with trapped air and decreased diffusion capacity. could this be copd  or is this normal ?

Accepted Answer

: How does  any test apply to me? To answer that it should be understood that tests results are taken into account with the things the patients, says, the examination, lab tests, and all other diagnostic tests. This may be a less common lung issue, COPD is possible but seems less likely. Speak to your doctor

Question 2

is there a relationship to always having lots of energy and a high normal diffusion capacity shown on a pulmonary function test?

Accepted Answer

: No, I do not think so.

Question 3

had pulmonary function test done with impression "mild restrictive defect" and "reduced diffusion".what could these mean?hyperreact. by methacholine

Accepted Answer

Different things:: it would be best to discuss in details with your doctor.. Restrictive means reduced ability of lungs to expand, as opposed to obstructive, which refers to the ease of passage of air through airways (and picked up by methacholine provocation). Diffusion is process of transfer of oxygen across the lungs membranes.. I would think they all needed to be considered in the clinical context..Good luck!

Question 4

i did a pulmonary function test what does it mean when my gas exchange levels are only 50%?

Accepted Answer

DLCO?: If you are referring to the DLCO value, then you may have some scarring in your lungs.  Need to consult a pulmonologist.

Question 5

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 6

my dr says i have acute interstitial lung disease and wants to do a pulmonary function test and high resolution ct scan. what does all of this mean?

Accepted Answer

Not simple pneumonia: For a simple pneumonia, the initial x-rays can provide classical features and the doc can send you on your way with simple treatment. Interstitial lung disease requires a more involved evaluation because the potential causes are quite diverse. Differentiating a simple transient from a long term issue is important to identify a cause and course of treatment.

Question 7

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 8

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 9

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 10

i am having discomfort in my lungs following a pulmonary function test.  could this be a problem?

Accepted Answer

No: Pulmonary function tests do not cause any damage.
