I know you do not like to give medical advice. But these are just the results of a lung Test of a grandfather when he was 75 years old. His doctor did say anything after reading the report. We wonder if the test was okay. He never smoked. But the report is hard to understand. For privacy no name is given.

FEV1 is the amount of air forcibly expelled in 1 second. FVC is total forced capacity. They gave him a bronchodilator and it did not improve the test results. " moderately severe (pulmonary) restriction. He may not have smoked but could have been exposed to dust, asbestos or other substances that could have possibly caused this issue. pO2 is oxygen saturation in the blood. Max is 100, 96 is good.
