呼吸衰竭的概念、诊断、分型和分级呼吸衰竭是由于呼吸功能的严重损害,不能进行有效的气体交换,以致缺氧,伴有或不伴有二氧化碳潴留,引起一系列病理生理改变和临床表现,称为呼吸衰竭。呼吸衰竭的分类方法有多种,如按病程分为急性和慢性;按病理生理改变分为通气性和换气性;按病变部位分为中枢性和周围性;按血气分析的改变分为Ⅰ型和Ⅱ型。为了诊断、分型和分级的概念明确,指征确切,且能反映病理生理变化,并有利于指导临床实际,目前认为,按血气分析的改变为
The concept of respiratory failure, diagnosis, classification and classification of respiratory failure is due to severe respiratory damage, can not be effective gas exchange, resulting in hypoxia, with or without carbon dioxide retention, causing a series of pathophysiological changes and clinical manifestations , Known as respiratory failure. There are many kinds of classification of respiratory failure, such as acute and chronic according to the course of the disease; according to the pathophysiological changes are divided into ventilation and ventilation; According to the lesion is divided into central and peripheral; according to changes in blood gas analysis is divided into Ⅰ Type and type II. For the diagnosis, classification and classification of the concept of a clear, accurate indications, and can reflect the pathophysiological changes, and is conducive to guiding clinical practice, the current view, according to the change of blood gas analysis
