I would appreciate if you could review the results of my PFT and give me your analysis or opinion. I am 61 (well in a month anyway) and 70.5 inches tall and 170 pounds. I know almost nothing about most of what is contained here with the exception of PEF and FEV1. I am somewhat concerned by the 145% of predicted for RV and 136% of predicted for FRC. The FEF25-75% and the FEV1/FVC are also concerning. I have no idea whether the DLCO results being over 100% is a good thing or a bad thing so would appreciate your explanation of those numbers as well. Actually I guess I am asking for an interpretation of the entire report.

The first thing to do is to confirm that the PFT values are valid; performed in a reliable lab by an experienced technician and interpreted by a qualified physician.
Greater than predicted values indicate lung hyperinflation. This phenomenon is characteristic of what are called obstructive lung diseases that include Asthma, COPD, Emphysema. The degree of severity of these diseases varies from Mild to Very Severe.
A reduction in FEV1/FVC ratio ( 100% is inconsistent with the finding of hyperinflation and reduced FEV1. I suggest that you discuss this apparent discrepancy with the physician who ordered your testing.
