What constitutes Gold 2 (moderate) in COPD airflow limitation?

FEV1 < 30% predicted
FEV1 50% - < 80% predicted
FEV1 30% - < 50% predicted
FEV1 >/= 80% predicted

The correct answer is: FEV1 50% - < 80% predicted

Gold 2 (moderate) in COPD airflow limitation is classified as an FEV1 (forced expiratory volume in one second) between 50% and less than 80% of the predicted value. This indicates a moderate level of airflow limitation in the lungs. Option A is incorrect because an FEV1 less than 30% predicted would fall under the category of severe airflow limitation, not moderate. Option C is also incorrect because an FEV1 between 30% and less than 50% would be classified as Gold 3 (severe) COPD. Option D is incorrect because an FEV1 equal to or greater than 80% predicted falls within the range of mild or normal lung function.
