Breathing simulator is designed for the development and maintenance of an economical breathing. Exerciser breathing characterized in that it comprises a container main and capacitance further, the container generally comprises a face mask, the hole inlet to the valve inlet, a source of high air vibrations, made of an electric sound transmitter, the source of low-frequency air vibrations, made of a tube resonator with valves, mounted on the ends of the tube to position the free air outlet from the tube, liquid manovakuumetr twin-tube, control devices and notification containing ii dangerous concentrations of oxygen and carbon dioxide, additional capacity comprises a hole shutoff. The simulator main respiratory capacity may be made volume of 0.1-1.0 l, and additional capacity may be made volume 0.2-2.0 l by the use of containers of various sizes. The simulator respiratory resonator tube low-frequency source of air vibrations may be made of an elastic material. The simulator source of low-frequency breathing air vibrations, made of a tube resonator with valves can generate air vibrations in a specific frequency range, e.g. in the range 2-5 Hz, fixed due to valve opening due to a technologically and supported in the vessel core overpressure air and underpressure within + -10-25 mm water. Art. The technical result provided by the reduced set of features, is to increase the efficiency and safety of the development and maintenance of an economical breathing. Breathing simulator can be used in medicine, sports, professional activities and daily lives of people for the recovery.
