Chronic obstructive pulmonary disease (COPD) is a chronic disorder with substantial comorbidity and major effects attributable to the high morbidity and mortality rates. Despite an increasing evidence base, some important controversies in COPD management still exist.

The classic way to define COPD has been based on spirometric criteria, but more relevant diagnostic methods are needed that can be used to describe COPD severity and comorbidity.
