GOLD system : Classify COPD patients based on airflow limitation. Pulmonary function test use the capacity of a pat to exhale all inspired air in one second. Fev1 and fvc/fev1 measurements decrease with increasing severity of lung obstruction. Stage 3 severe COPD fev1 30-45% of normal and stage 4 very severe COPD with fevi less than 30% if normal.

No: They are different, serious processes. COPD causes chronic over inflation of the lungs due to loss of elasticity in the airways (the air can't get out). Emphysema is a chronic destruction of the lung tissue that leads to poor oxygen exchange (the air can't get in the blood).
