Spirometry is a method of assessing lung function by measuring the volume of air that can be expelled from the lungs following maximal inspiration The indices derived from this forced expiratory manoeuvre have become the most accurate, repeatable and reliable way of confirming the diagnosis of COPD When these values are compared to predicted normal values, the presence (or absence) of COPD – and its severity – can be confirmed • Spirometry is the gold standard investigation in the diagnosis (and exclusion) of chronic obstructive pulmonary disease (COPD) and in assessing its severity • In the presence of consistent symptoms, clinically significant COPD can be diagnosed when forced expiratory volume in second/forced vital capacity (FEV1 /FVC)
