While international bodies, such as the Global Initiative for Chronic Obstructive Lung Disease (GOLD), have varied in their classification system for COPD severity over the years, there has long been recognition that pathologically [2] and clinically [3] relevant disease may be present before spirometry becomes abnormal. Indeed, GOLD included “at risk” as a disease stage in early iterations of their documents on COPD.Radiological measures of gas trapping, in particular due to small airways disease, may aid identification of smokers at risk of progression to COPD. Further research is needed on how to bring gas trapping measurement into routine clinical practice. http://bit.ly/33QxC9F ER -
