Patients suffering from uni- or bilateral recurrent laryngeal paresis were tested by means of spirometric and complex functional capacity tests. The results obtained from patients with unilateral paresis (spirometry, spiroergometry, acid-base equilibrium, oxygen tension) did not differ from those of the control group. A restriction of the functional capacity due to disorders of breathing was not found. In patients with bilateral paresis, physiologic parameters were always influenced by the respiratory tract stenosis. Functional tests resulted in alveolar hypoventilation up to total respiratory failure connected with decreased ergometric values. The results also gave an insight into the pathophysiologic mechanisms of the respiratory obstruction as a result of the stenosis under conditions of physical strain. Suggestions for evaluating the physical functional capacity of patients are given.
对患有单侧或双侧喉返神经麻痹的患者进行了肺活量测定和综合功能能力测试。单侧麻痹患者的测试结果（肺活量测定、运动心肺功能测试、酸碱平衡、氧分压）与对照组无差异。未发现因呼吸障碍导致的功能能力受限。双侧麻痹患者的生理参数总是受到呼吸道狭窄的影响。功能测试导致肺泡通气不足，直至出现与运动心肺功能值降低相关的完全呼吸衰竭。研究结果还深入了解了在身体负荷条件下，由于狭窄导致呼吸阻塞的病理生理机制。文中给出了评估患者身体功能能力的建议。
