A high frequency artificial breathing device is designed to transmit high frequency pressure vibrations generated by frequent reciprocation of a piston in a vibration producing device to a patient pass, and to vibrate gases in a patient pass. In the present invention, some pressure vibrations generated by the vibration producing device are cut off or absorbed by a cross-sectional area regulating member equipped to a vibration transmitting pass which transmits the pressure vibrations to the patient pass, a changeable volume soft bag, or a bag connected to the vibration producing device through a flow rate regulating member. Cutting off or absorption of some pressure vibrations generated by the vibration producing device varies pressure vibration amplitude transmitted to the patient pass. Therefore, when an exchange amount is adjusted by the artificial breathing device depending on the patient's condition etc., changing a piston stroke is not required during the devise's operation, and a normal rotary motor can be used as a motor for driving the piston.
