I had a Pulmonary Function Test in 2005 and just had another one a few weeks ago (Oct.2009). I am wondering if anyone can help me understand the results.
Conclusions of 2005 Test: "The FVC,FEV1/FVC ratio and FEF25-75% are within normal limits, but there is curvature to the flow volume loop suggesting minimal small airway disease. The FVC is reduced relative to the SVC indicating air trapping. Lung volumes are within normal limits. Diffusing capacity is normal. However, the diffusing capacity was not corrected for the patient's hemoglobin. Minimal airway obstruction is present suggesting small airway disease. Pulmonary Function Diagnosis: Minimal Obstructive Airways Disease."
Conclusions of 2009 Test: " Although the FEV1 and FVC are reduced, the FEV1/FVC ratio is increased. Following the administration of bronchodilators, there is no significant response. The reduction in FVC would suggest a restrictive process. However, the presence of restriction should be confirmed by measurement of lung volumes."
FVC (L): 69%Pred.
FEV1 (L): 77% Pred.
FEV1/FVC %: 111%Pred.
FEF25% (L/sec): 98%Pred.
FEF75%(L/sec): 76%Pred.
FEF25-27%(L/sec): 92%Pred.
FEF Max (L/sec): 86%Pred.
Can anyone help interpret these results for me? And what does "administration of a bronchodilator" mean? To my knowledge, they never administered anything to me during the test at all!
Note: Other symptoms I have at this time: muscle twitches, tingling, bilateral clonus, burning in lungs, lack of energy/endurance, headaches.
Thanks for any help that you can give me!
