GOLD 2 COPD corresponds to which FEV1 range?

GOLD 2 COPD corresponds to which FEV1 range?

• A. FEV1 ≥80% predicted, mild airflow limitation.
• B. FEV1 <30% predicted, extreme limitation.
• C. FEV1 50-79% predicted, moderate limitation.
• D. FEV1 30-49% predicted, severe limitation.

Answer: (C)

GOLD COPD staging uses how much air a person can forcefully exhale in one second, expressed as a percentage of the predicted value for that person after bronchodilator. A FEV1 between 50% and 79% of predicted reflects moderate obstruction, which is categorized as GOLD 2. So the moderate limitation range is the correct match. The ranges ≥80% is mild, 30–49% is severe, and below 30% is very severe.
