WebIn people over 70 years old, the FEV 1/FVC ratio may need to be lowered to 0.65 as a lower limit of normal. Conversely, in people under 45, using a ratio of 0.7 may result in under-diagnosis of airway obstruction. To avoid both of these problems, many experts recommend use of the lower limit of normal for each population.
