慢性阻塞性肺疾病(简称慢阻肺)是常见的呼吸系统疾病,是一种具有气流受限为特征的对人类健康危害较大的疾病,其气流受限不完全可逆,呈进行性发展,与肺脏对吸入烟草烟雾等有害气体或颗粒的异常炎症反应有关,是可以预防和治疗的。慢阻肺主要累及肺脏,但也可引起全身(或称肺外)的不良效应。肺功能检查对其诊断有重要意义。诊断根据吸烟等发病危险因素、临床症状、体征及肺功能检查等综合分析确定,但不完全可逆的气流受限是慢阻肺诊断的必备条件。吸入支气管舒张药后1秒钟用
Chronic obstructive pulmonary disease (COPD) is a common respiratory disease, which is a disease characterized by limited air flow and endangering human health. The air flow limitation is not completely reversible and progresses progressively. And lungs on the inhalation of tobacco smoke and other harmful gases or particles of the abnormal inflammatory response, can be prevented and treated. Chronic obstructive pulmonary disease mainly affects the lungs, but can also cause systemic (or extrapulmonary) adverse effects. Pulmonary function tests for its diagnosis of great significance. Diagnosis based on risk factors such as smoking and other clinical symptoms, signs and pulmonary function tests to determine a comprehensive analysis, but not fully reversible airflow limitation is a prerequisite for COPD diagnosis. 1 second after bronchodilator inhalation
