WebThe diagnosis of VCD was based, whenever possible, on direct laryngoscopy or reversible flattening of the inspiratory portion of the flow–volume loop during observed stridor. However, 17 of the 49, … WebFlow volume loops (FVL) showed flattening of both inspiratory and expiratory curves (suggestive of a fixed UAO) (Fig.1-A). The ratio between maximum expiratory and inspiratory flows at 50% of forced vital capacity (FEF 50/FIF 50) was 1.5 (suggestive of a variable extra-thoracic UAO). WebThe diagnosis of VCD may be difficult because physical exam and spirometry may be normal between episodes. During symptomatic episodes, spirometry typically reveals variable extrathoracic airway obstruction (truncated inspiratory flow volume loop). The gold standard for identifying VCD is flexible fiberoptic rhinolaryngoscopy. simon longnight hamilton
