通气是呼吸生理最主要的组成部分。弥散以利氧之吸收和二氧化碳之排出,以及血流输送氧至身体各部,无不取决于通气功能。从肺脏解剖观点论,有数通气必须有正常的肺容积和通畅的呼吸道,前者关系到肺泡组织的容量,后者关系到支气管气流速度;肺泡组织和支气管病变的部位和范围不同,通气障碍将产生不 Ventilation is the most important component of respiratory physiology. Dispersion to facilitate the absorption of oxygen and the discharge of carbon dioxide, and blood flow to the body parts of oxygen, all depends on the ventilation function. From the perspective of lung anatomy, there are several ventilation must have a normal lung volume and patency of the respiratory tract, the former is related to the capacity of alveolar tissue, which is related to the bronchial air flow rate; alveolar tissue and bronchial lesions of different parts and scope of ventilation disorders will produce Do not
