1 哮喘和气道高反应性 哮喘急性发作时,气道狭窄的出现和严重程度与气道敏感性增加有关,也与对吸入支气管致痉剂刺激的最大反应增加有关。这两者正是气道高反应性的主要异常改变.即气道高反应性是指在遇到一种适当刺激物时产生气道阻塞的趋势。它是一种反映哮喘患者气道功能异常状态的指标.并可预计疾病的长期预后。2 气道高反应性的病因学 气道高反应性可由遗传
1 In the acute episodes of asthma and airway hyperresponsiveness asthma, the presence and severity of airway stenosis are associated with increased airway sensitivity and with an increased maximum response to inhaled bronchospasm stimulation. Both of these are the major abnormal changes in airway hyperresponsiveness, ie, airway hyperresponsiveness refers to the tendency to develop airway obstruction upon encountering a suitable stimulus. It is an indicator of abnormal airway function in patients with asthma and predicts the long-term prognosis of the disease. 2 airway hyperresponsiveness etiology Airway hyperresponsiveness can be inherited
