Interpretation of test results - 3

In this patient there is a marked bronchodilator effect, indicating that there was significant bronchomotor tone. In the great majority of cases an increase in the FEV1 is associated with an increase in the FVC; in this case the FVC returns to the normal range, while the FEV1 still falls just below the lower limit of normal. The next page shows the more extensive interpretation.

  Baseline Post test
