  1. None of the five parameters is normal
  2. Because both the FEV1 and the FEV1/FVC are low, this is an obstructive pattern. Because the FVC is only 69% of predicted, there could also be a restrictive issue as well. However, this can only be confirmed by a decrease in the total lung capacity.

  4. No bronchodilator was administered.
