Is this normal?

I am 43yr. old female. - 64in. I recently had a pulmonary test performed because a chest x-ray showed hyper-extension. My results are as follows:

Pre Albuteral

                       PRED        MEAS         %
FVC               3.48           2.97          85
FEV1              2.68            2.71          101
FEV/FCV          77              91             14
PEF                 369            435            118
FEF25-75%      3.10           3.30           106

Post Albuterol

                          PRED        MEAS         %
FVC                    3.48           2.91            84
FEV1                  2.68            2.78           104
FEV1/FVC%        77               95              18
PEF                     369            417             113
FEF25-75%          3.10            3.74            121

Can you interpret please? My doctor doesnt seem concerned . He said I definitely do not have COPD but still show some obstruction. Are these Values normal?

The x-ray report probably said hyper-inflation.  It means that the lungs appear to be overly expanded, something that can be an early sign of chronic obstructive pulmonary disease (COPD).  It is a somewhat subjective interpretation by the radiologist and not a good way to make the diagnosis.  Pulmonary function tests (PFTs) are a much better way and your results are not at all suggestive of COPD.  The results do not show obstruction.

If anything the results are more consistent with restriction, or restrictive lung disease, a term that implies that one’s lungs are smaller than predicted.  In this regard, your results are within normal limits, albeit at the lower range of normal values.  Normal lung function is a wide range of values, rather than a normal value.  The predicted value is the mean value of that range.

However, since the issue of restrictive lung disease has been raised and, especially if you have any respiratory symptoms, such as shortness of breath with exertion, you should consider discussing these findings with a lung specialist, also known as a pulmonologist.
