What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected?

When the patient with emphysema was selected lung values changed (from those of the normal patient) in the spirogram are:

ERV, IRV, RV, FVC, FEV1, FEV1 %

The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph like structure obtained by the respiratory movements) is measured by spirometer.
