Stages of COPD
Dr. Keith Jamal Robinson, Pulmonologist with Baptist Health South Florida, explains the stages of Chronic Obstructive Pulmonary Disease (COPD) are mild, moderate, severe, and very severe, and they are based on how much airflow obstruction they can measure.
He also points out most patients go three years without a qualified diagnosis, and some patients have a different trajectory in their lung function loss.
