Every healthcare professional involved in the care of patients with chronic obstructive pulmonary disease understands the challenge. COPD is one of the world’s leading causes of illness and death, affecting more than 300 million people and placing an enormous burden on healthcare systems. Although treatment options have improved significantly over recent decades, clinicians continue to face a fundamental problem. They mostly rely on diagnostic measurements that do not fully capture the disease’s complexity. For many years, a simple form of spirometry has been the cornerstone of COPD diagnosis and management. The ratio of forced expiratory volume in one second and forced vital capacity is relatively easy and inexpensive to measure. It is therefore widely available and is supported by decades of clinical experience. This ratio has become so firmly established as a measure of the disease that it is virtually impossible to imagine COPD assessment without it. More
