Does this PFT show Asthma?
by win904, May 09, 2009 05:54PM
I have severe allergic Asthma and have been in the hospital and urgent care numerous times this year, I've been on massive steriods this year. I'm taking Q-var, Symbicort and Zyflo along with Allergra. My peak flow goes up and down at the drop of a hat. I'm on Xoliar and weekly allergy shots too! I have a continual cough that will wake me up at night and I cough during the day from time to time, again my peak flow will drop when I cough.
My Pulmonary function test results were as follows:
FVC 55% Post 7%, FEV1 L 61% Post 2%, FEV1/FVC%112%, FEF25-75 87%, post -20% FEFmax 95% post 6%
Lung Volumes:
VC 61%, IC 77%, ERV 26%, FRC 54%, RV 69%, TLC 64%, RV/TLC 108%
Diffusion Capacity
D/VASB 178%, DSB 114%, VAsb 64%
This report showed Moderate restrictive ventilatory impairment with no significant improvement post bronchodilator. Can this be the cause of my servere asthma? No sign of upper airway restriction on the report. My dad had interstitial lung disease, COPD and emphysema.
Can anyone tell me what is up? I'm heading out to the National Jewish in June, thanks!

The limited spirometry results submitted are consistent with restrictive pulmonary disease.
For reasons, not well explained, some people with asthma develop spirometry-defined restrictive lung disease. This is seen mostly in instances of severe asthma, especially those with onset at an older age. In most cases of this type the pulmonary function abnormalities are not or, at best, not very likely to be reversible.
Then again, you could, especially with your family history of interstitial lung disease, have an interstitial lung disease, superimposed on asthma.
You have made a good decision to come to National Jewish where there has been great experience with restrictive lung disease, obstructive lung disease and with people presenting with features of each.
Good luck.
