The minimum acceptable FEV1/FVC ratio for older adults is generally considered to be 65%. This is because as people age, their lung function naturally declines, and the FEV1/FVC ratio, which measures the proportion of a person's lung capacity that can be expelled in the first second of a forced breath, decreases. A ratio below 65% in older adults may indicate obstructive lung disease.
