The concept of Breathing Coordination (TM) was the result of ten years of medical research started in 1958 by Carl Stough and elaborated by Reece Stough in 1964 for advanced researchers in the international respiratory field. Every physical and emotional problem, to some degree, is the result of an insufficiency of oxygen. The diaphragm works to achieve a maximum exhale. This is necessary in order to maintain a low residual volume of carbon dioxide in the lungs. The diaphragm, which is a primarily involuntary muscle-organ, is the foundation for the entire respiratory system. It affects the two other main systems of the body, the circulatory and nervous systems. The term Breathing Coordination is the name given to the exact way the respiratory system is designed to function at maximum efficiency with minimum effort.
