Lung Function Testing

[MDAVEY]

I had posted a few weeks ago about having to be seen by a lung specialist for some possible lung fibrosis. I had all of the breathing tests today and they said my lung capacity was normal but some of my other functions were lower than they should be. When I would try to blow out forcefully that was one that was kind of low on value. He said overall it looked pretty normal other than that. Can this still be healthy even with a few functions not quite at the level they should be?

Thanks, Mike

This is good news.  The so-called "normal values" are average values and, as with all averages, there is a range of truly normal values both above and below the "normal value."  With pulmonary fibrosis, the crucial values are forced vital capacity (FVC) and, if performed total lung capacity (TLC).  You should seek further clarification from the lung specialist about the significance of your values, with special attention to the diagnosis of pulmonary fibrosis.  Ask him:  "Do I have any signs of pulmonary fibrosis or any other lung disease?"

Looking at my post its kind of vague, I should have written some of the #'s down he was throwin out the other day. I do know at one point I inhaled 5.1 liters of air. I basically was wondering if someone with healthy lungs can do not so great on some of the lung function testing. Also I went for the CT Scan today so hopefully I will know soon.

Mike,
Heres a spirometry calculator and explanations of what they all are. Hope it helps explain a bit.

Thanks, I didn't get the numbers from the tech though. But when I go back for the results I will get a copy and check it out.

Thanks
