ABSTRACT
Abstract Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality worldwide. While the cut-off point to define airflow obstruction has been controversial, it is widely accepted that the spirometry test is vital, as well as performing it after using a bronchodilator. The 6-second spirometry and the forced expiratory volume in 1 second/forced expiratory volume in 6 seconds (FEV1/FEV6) have demonstrated validity for defining obstruction, and it would be advisable to incorporate them in the definitions of obstruction. Another relevant issue is that spirometry with borderline obstruction can vary over time, changing to above or below the cut-off point. Thus, surveillance should be considered over time, repeating the spirometry to have a greater certainty in the diagnosis. The objective of this article was to conduct an in-depth review of the controversies in the diagnosis of COPD. During the past years, COPD definition has been updated in different times; however, it is now considered more as a complex syndrome with systemic participation, requiring a multidimensional assessment, and not only a spirometry.
