随老年医学的研究深入,对老年肺功能特点研究日见增多。老年肺气肿形哎的机制很复杂,如生理性肺弹性减低,吸烟,长期理化因素的影响,以及无症状轻度支气管炎症等。本文旨在探讨老年人不同程度肺气肿与肺通气功能之间的关系,从而对通气功能可否反映肺气肿程度加以讨论。 With the deepening of the research in geriatrics, the research on the features of senile pulmonary function is increasing day by day. Elderly emphysema-like hey mechanism is very complex, such as reduced physiological elasticity of the lungs, smoking, long-term physical and chemical factors, and asymptomatic mild bronchial inflammation. The purpose of this article is to explore the relationship between pulmonary emphysema and different degrees of emphysema in the elderly and to discuss whether the ventilatory function can reflect the degree of emphysema.
