Inducible Laryngeal Obstruction: Excessive Dynamic Airway Collapse vs. Inducible Laryngeal Obstruction
Abstract
Excessive dynamic airway collapse (EDAC) describes focalized collapse of the trachea or main bronchi Commonly the posterior trachea invaginates while the cartilaginous tracheal ring structure is maintained Combination of posterior membrane laxity, airway and pleural pressures Typically observed in COPD, bronchiectasis and asthma Inducible laryngeal obstruction (ILO), previously called 'vocal cord dysfunction,' describes vocal cord closure with inspiratory wheezing Can be exercise induced and believed to occur in up to 10% of incorrectly diagnosed cases of asthma
