We describe 4 patients with reversible obstruction of the upper airways, a condition that usually presents with crises of dyspnea and respiratory sounds. No organic cause could be identified and the symptoms were initially confused with those of bronchial asthma. During episodes, the flow-volume curve suggested obstruction of the upper airways with poor reproducibility and repeatedly normal resistance values. Fiberoptic bronchoscopy allowed us to confirm the functional nature of the obstruction in these cases.
我们描述了4例上气道可逆性梗阻患者，这种情况通常表现为呼吸困难发作和呼吸音异常。未发现器质性病因，症状最初与支气管哮喘的症状混淆。发作期间，流量-容积曲线提示上气道梗阻，重复性差且阻力值反复正常。纤维支气管镜检查使我们能够证实这些病例中梗阻的功能性本质。
