| 摘 要： | 应用二维激光多普勒测试仪，对高频振荡通气的气体运输机理作了实验研究。按正交试验设计，得到了在不同状态下，树状人工肺各级气管的速度、湍流度及雷诺数。结果表明，ＨＦＯ是一种更为复杂的气体运输，为临床实践中应用ＨＦＯ输氧提供了理论依据。

| Abstract: | Describes an experimental study on the gas transport mechanism of ventilation based on high frequency oscillation (HFO) by using the Laser Doppler Velocimeter (LDV). According to the orthogonal experiment design, we obtained the velocity, turbulent and Reynolds numbers of the artificial tree lung trachea under the different parameters. The results indicate that the transverse velocity for the HFO cannot be neglected, and HFO is a more complicated gas transport. The experimental results provide the theoreical basis with HFO in clinical practice. |
