Abstract

The pendelluft effect on gas transport and exchange in high-frequency ventilation was investigated by using a simple computational model, in which each pendelluft zone extending over lower generations of airways consists of two branches performing asynchronous motion. The calculated results show that the gas exchange is markedly improved by the pendelluft when the sloshing of flow is generated between neighboring airways.

摘要

利用一个简单的计算模型研究了pendelluft效应在高频通气中对气体传输和交换的影响，其中每个延伸至较低级气道的pendelluft区域由两个进行异步运动的分支组成。计算结果表明，当相邻气道之间产生气流晃动时，pendelluft可显著改善气体交换。
