In GOLD (Global Initiative for COPD),which pulmonary measurements are used to assess the severity of COPD?
A) FEV1 and FEV1/FVC
B) FEV1 and TLC
C) FVC and PEFR
D) FEV1 and FEF₂₀₀‑₁₂₀₀

GOLD uses FEV1 (forced expiratory volume in one second) and FEV1/FVC (forced vital capacity) ratio to assess the severity of COPD. These measurements provide information about the extent of airway obstruction and can help guide treatment decisions. Other pulmonary measurements, such as FVC (forced vital capacity) and PEFR (peak expiratory flow rate), may be useful in assessing lung function but are not specific to COPD severity. FEF₂₀₀‑₁₂₀₀ (forced expiratory flow between 200-1200 mL) is not used by GOLD to assess COPD severity.
