A respiratory gas breathing line having a tubular connection to a person's trachea also has a connection to a gas supply line. A pressure sensor is located in the tubular connection and it is connected to pressure control means which is also connected to the tubular connection and to the gas supply. In addition, pressure sensor is located in the tubular connection and connected to pressure control means connected between the respiratory breathing line and the gas supply. A pressure reducer, a dosing valve and an inspiration valve are located in series in the connection between the gas supply and the tubular connection. The pressure control means includes a frequency control device having a housing with a control chamber therein which is separated by adjustable partition means into an inspiration control chamber and an expiration control chamber which may be adjusted in size relatively. A frequency valve is provided with an inspiration line connection to the inspiration chamber and an expiration line connected to the expiration chamber. Pneumatic inspiration control elements are located in the inspiration line and the expiration line and a second inspiration line and respiration line is connected from the respective inspiration and respiration chambers to the inspiration valve in order to open and close the valve in accordance with the setting of the control system.
