肺阳虚是指肺阳不足导致的以温煦不足及宣发推动、功能衰退为表现的一类病证。肺阳虚是慢性阻塞性肺疾病(慢阻肺)稳定期证型之一,寒邪侵袭、痰饮内停、久病伤气、他脏久病是其主要病因,肺阳亏虚、痰饮内停、肺气壅塞导致肺失宣降,影响肺脏正常生理功能为其根本病机。治疗应以补肺虚、散表邪、祛痰饮、防变证为基本治疗原则,可在补肺阳方基础上针对不同合并症状辨证施治。

The deficiency of lung yang is a kind of syndrome manifested as tailure of warming and laypofunction caused by lung yang insufficiency. Lung yang deficiency is one of the stable phases of chronic obstructive pulmonary disease（COPD）. We think that the cold pathogen invasion,phlegm and fluid retention, prolonged diseases damaging qi,prolonged diseases of other organs are the major etiology of COPD. Lung yang deficiency,phlegm and fluid retention,lung qi obstruction leading to failure of dispersing and descending of the lung are the essential pathogeneses of COPD. Syndrome differentiation and treatment of invigorat- ing the deficiency ,dispelling the exogenous pathogens ,resolving the phlegm,preventing the complications are the basic principles of treating lung yang deficiency based on prescriptions of tonifying the lung yang.
