自1973年有人报告间歇指令通气(IMV)用于成年患者撤离通气支持后,它就成为人们最常使用的一种主要机械通气方式.1979年报道压力支持通气(PSV)可使自主呼吸患者的潮气量(V_T)增加,呼吸功降低,因其用于呼吸暂停或慢性呼吸暂停患者时不够安全,故常与同步间歇指令通气(SIMV)合用.气道压力释放通气(Airway pressurerelease ventilation,APRV)可增加患者的肺泡通气,他们用于连续气道正压通气(CPAP)而又难以自主呼吸来维持 PaCO_2患者,APRV 显著特征是
It has become one of the most commonly used forms of mechanical ventilation since intermittent mandatory ventilation (IMV) was reported for evacuation support in adult patients in 1973. Pressure support ventilation (PSV) was reported in 1979 to allow spontaneous breathing of patients Increased tidal volume (V_T), reduced work-breathing, often unsuitable for use in patients with apnea or chronic apnea, and is often associated with systolic SIMV. Airway pressurerelease ventilation (APRV) Increase in patients with alveolar ventilation, they are used for continuous positive airway pressure (CPAP) and difficult to spontaneously breathe to maintain PaCO_2 patients, APRV significant features
