一、临床应用通气机时,如何选择定压型和定容型? 答:定压型是以呼吸道预定压力作为触发吸气或呼气的条件;定容型则是靠将预定一定气体容量压入呼吸道,作为触发吸气和呼气条件,两者各具特点。具体使用条件如下:(一)定压型(如HQ-Z-I,YR-Ⅱ及Bird等):①患者有自主呼吸,需同步作辅助呼吸;②肺内病变较轻,吸气力较大,易与通气机同步及保证潮气量;③停用通气机前作
First, the clinical application of ventilator, how to choose the type of constant pressure and constant volume? A: constant pressure type is based on the pressure of the respiratory tract as a trigger inhalation or exhalation conditions; constant volume is by a predetermined gas volume pressure Into the respiratory tract, as a trigger inhalation and expiration conditions, both have their own characteristics. Specific conditions of use are as follows: (a) constant pressure type (such as HQ-ZI, YR-Ⅱ and Bird, etc.): ① patients have spontaneous breathing, need to be synchronized for assisted breathing; ② lung lesions lighter, Easy to synchronize with the ventilator and ensure that the tidal volume; ③ disable the ventilator before
