摘要
测定了30例上气道梗阻(UAO)的肺功能改变,结果显示胸内型UAO以呼气相早中期流速受限明显,而胸外型UAO以吸气相流速受限尤著,固定型则双相流速均明显受限,肺功能对UAO的评价应按不同类型分别判断,本文并提出了诊断标准,UAO患者的支气管扩张试验阴性,若上气道梗阻得到解除后,反映阻塞性障碍的肺功能指标应得到相应的改善。
Lung function change was studied in 30 patients with upper airway obstruction (UAO). Results shovved that obvious expiratory flow limit was found in intrathoraxic UAO, inspiratory flow limit was found in extrathoraxic UAO, while both inspiratory and expiratory flow limits were found in fixed UAO. Evaluation of UAO by pulmonary function testing should be assessed by their obstructive types. Diagnosis criteria was studied. Bronchodilation test was negative in UAO patients. Lung function parameters indicating UAO should be improved once obstruction being released.
