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.
