With the failure of both VCV and PCV to offer benefits, while reducing patient risk, a new mode, PCV-VG was introduced, using a decelerating flow pattern and constant pressure. With PCV-VG, ventilator parameters are automatically adjusted with each breath, calculating lung compl...
[Key words]mechanical ventilation;PCV-VG 呼吸支持是维持患者呼吸、改善氧供的重要方式，机械通气是呼吸支持的主要手段，尤其应用在临床麻醉中，但是不恰当的通气策略会导致呼吸机相关肺损伤(ventilator associated lung injury,VALI),延长机械通气时间和住院时间，增加患者死亡率⑴。容量控制通气模式(volume-controlled ven...
