Which GOLD stage corresponds to FEV1 50-79% predicted?

Which GOLD stage corresponds to FEV1 50-79% predicted?

• A. GOLD 4
• B. GOLD 1
• C. GOLD 3
• D. GOLD 2

Answer: (D)

FEV1 percent predicted is used to gauge COPD severity. FEV1 measures how much air you can forcibly exhale in one second, and comparing it to the predicted value for your demographics gives a percent. The GOLD system defines stages as: ≥80% (mild), 50–79% (moderate), 30–49% (severe), and <30% (very severe). Therefore, an FEV1 in the 50–79% range corresponds to the moderate stage.
