    Tracheomalacia is a term used to describe weakness of the trachea. Strictly speaking, tracheomalacia means weakness of cartilaginous structures of the trachea, while excessive dynamic airway collapse (EDAC) describes invagination of the posterior membrane of the trachea leading to a ≥50% reduction in airway lumen.1 Tracheomalacia and EDAC are thought to exist in a significant portion of patients suffering from chronic obstructive pulmonary disease (COPD).2
