慢性阻塞性肺疾病(COPD)是一种由气道和肺实质的慢性炎症引起的进行性通气受限的综合征。COPD主要生理学异常是一秒钟用力呼气容积(FEV1)加速下降,下降速度由正常时的大约30ml/年加重到60ml/年,同时呼吸问卷调查(SGRQ)生活质量评分也降低。胆碱能神经是呼吸道的主要支配神经。
Chronic obstructive pulmonary disease (COPD) is a syndrome of progressive ventilatory limitation caused by chronic inflammation of the airways and lung parenchyma. The main physiological abnormality in COPD was accelerated expiratory volume in one second forced expiratory volume (FEV1), which was increased from about 30ml / year to 60ml / year in normal time, and also decreased in SGRQ. Cholinergic nerve is the main dominant nerve of the respiratory tract.
