Diagnosing chronic obstructive pulmonary disease (COPD) can be complex and requires
considerable clinical skill. It is rather like putting together the pieces of a jigsaw
puzzle. But don’t despair. In this article, we take you through the key steps. A careful
history, particularly in smokers or ex-smokers who complain of breathlessness,
followed by clinical examination may indicate possible COPD. Further steps must then be taken
to exclude other causes of respiratory symptoms and spirometry is essential in diagnosing
airflow obstruction, which may help to confirm the diagnosis of COPD.
