A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs) after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs in inspiration is observed to reoccur following a deep breath or swallowing. The procedure may thus help diagnosing the site of exercise-induced obstruction when laryngoscopy is not available and identify re-inducers of laryngeal dysfunction.
一名疑似运动诱发喉梗阻和哮喘的儿童在运动激发试验后接受喉镜检查和呼吸阻力（Rrs）检测。运动停止后即刻，吸气时可见的喉部内收表现为Rrs的阵发性增加。虽然在运动恢复后期呼吸看似已恢复正常，但在深呼吸或吞咽后，吸气时Rrs的模式会再次出现。因此，当无法进行喉镜检查时，该检查方法可能有助于诊断运动诱发梗阻的部位，并识别喉功能障碍的再次诱发因素。
