本文收集了有关机械通气和非传统辅助机械通气治疗小儿呼吸衰竭研究的进展情况 ,现综述如下。1　肺保护性机械通气及其策略呼吸衰竭时因肺泡萎陷引起功能残气量 (ＦＲＣ)减少 ,可导致肺通气容量减少、肺顺应性下降 ,而传统的机械通气则是应用高通气压来保证潮气量和每分钟通气 This article collected the progress of mechanical ventilation and non-traditional auxiliary mechanical ventilation treatment of respiratory failure in children, are summarized below. 1 Lung protective mechanical ventilation and its strategies Respiratory failure due to alveolar collapse caused by functional residual capacity (FRC) decreased, can lead to decreased lung capacity, pulmonary compliance decreased, while the traditional mechanical ventilation is the use of high-pressure to ensure moisture Ventilation and ventilation every minute
