高频通气(high frequency Ventilation,HFV)是一种新型的机械通气技术,引起人们广泛的兴趣。现已成为国内外医学界中的一项研究课题。本文将当前国内外有关HFV研究和应用的近况综述如下。一、概述HFV系瑞典Sj(?)strand于1967年首创的一种新型机械通气,采用60～110次/分的高频通气,其潮气量低(略高于死腔通气),不仅氧合和通气良好,而且气道峰值压(PIP)和平均气道压(PAW)低,对循环以微小影响,而命名为高频正压通气(HFPPV)。嗣后他们的实验和临床观察证明,HFV能提高充足的肺泡通 High frequency ventilation (HFV) is a new type of mechanical ventilation technology that has aroused widespread interest. Has now become a research topic in the medical profession at home and abroad. This article summarizes current research and application of HFV at home and abroad as follows. First, an overview HFV Sweden Sj? Strand in 1967, a new type of mechanical ventilation, the use of 60 to 110 beats / min of high frequency ventilation, the tidal volume is low (slightly higher than the dead space ventilation), not only oxygenated And ventilated well, with low PIP and PAW, and a small effect on circulation, and was named HFPPV. Subsequently, their experimental and clinical observations have shown that HFV can improve adequate alveolar pass
