In the European guidelines, the presence of mild airflow limitation is recognised by a reduction in the ratio of FEV1 to VC or FVC (<1.64 residual standard deviation below predicted FEV1/VC). In both sets of guidelines, severity is based on the measured FEV1 as a percent of predicted FEV1. The European guidelines define 3 stages of severity:
1. FEV1>=70% predicted : Mild
2. FEV1=50-69% predicted : Moderate
3. FEV1<50% predicted : Severe
