We make an experimental HFV apparatus in which the mass-spring system is utilized as the vibration actuator. When this apparatus is operated near the characteristic frequency of the mechanical vibration system, the efficiency is quite good and trivial motor is enough to realize the vibrating flow for the experimental ventilator. In this paper we first investigate the flow-frequency relations and found that above the characteristic frequency of the mechanical vibration system the oscillating volume of flow is nearly constant. Next we check the gas exchange between model-lung and atmosphere and obtain the relations among pressure vs. flow rate, pressure vs. rate of gas exchange.
我们制作了一种实验性高频通气（HFV）装置，其中质量 - 弹簧系统被用作振动致动器。当该装置在机械振动系统的特征频率附近运行时，效率相当高，并且小型电机就足以实现实验性呼吸机的振动气流。在本文中，我们首先研究了气流 - 频率关系，发现高于机械振动系统的特征频率时，振荡气流体积几乎恒定。接下来，我们检查模型肺与大气之间的气体交换，并获得压力与流速、压力与气体交换率之间的关系。
