慢性阻塞性肺疾病(COPD)与支气管哮喘均为呼吸系统慢性炎症性疾病,两者均存在不同程度的气流受阻,均出现呼吸困难、气道分泌增多、支气管缩窄等临床特征,严重影响患者及其家人的生活质量。由于COPD与支气管哮喘存在许多相似之处,因此,对于两种疾病的鉴别与诊断十分困难。近年来,许多专家学者对两种疾病的区别与联系展开了积极的探讨,成为国内外关注的热点之一。本研究通过对比观察COPD与COPD合并支气管哮喘在肺通气功能、支气管扩张试验、气道阻力方面的临床特征,为两种疾病的鉴别诊断提
Chronic obstructive pulmonary disease (COPD) and bronchial asthma are respiratory chronic inflammatory diseases, both have varying degrees of airflow obstruction, all appear dyspnea, increased airway secretion, bronchial constriction and other clinical features, seriously affecting patients And the quality of life of their families.
