脉冲振荡肺功能在儿童小气道功能障碍疾病中的临床应用

Clinical application of impulse oscillometry in children with small airway dysfunction

小气道功能障碍已被证实广泛存在于哮喘、慢性阻塞性肺病等疾病中,其临床表现不典型,不易被早期发现。及时明确小气道功能障碍,有利于疾病的早期治疗、准确判断及改善预后。脉冲振荡肺功能是一种新型的肺功能检测方式,目前被广泛认为是评估小气道功能最敏感的技术之一,其可以测量被检查者在平静呼吸时呼吸系统的阻抗(R)和电抗(X),了解中央和外周气道阻塞情况,同时具有无创、操作简单、重复性好等优点。

Small airway dysfunction has been proved to be widespread in asthma,chronic obstructive pulmonary disease and other diseases,and its clinical manifestations are atypical and difficult to be detected early.Identifying SAD in time is conducive to early treatment,accurate judgment and improved prognosis of the disease.Impulse oscillometry is a new lung function test that is widely recognized as one of the most sensitive techniques for assessing small airway function.It can measure the resistance(R)and reactance(X)of the respiratory system of the inspected person during normal respiration,so as to understand the central and peripheral airway obstruction,and has the advantages of non-invasive,simple operation and good repeatability.
