Change of Blood Oxygen Concentration, Electric Impedance of Skin and Pulse Wave Fractal Dimension by Different Kinds of Breathing

The way of respiration can be consciously changed to some extent. By changing respiration, an effect appears in other paralysis attention organs, and it is used for bed rest and meditation. In this study, three kinds of breathing: usual respiration (usual respiration done without conscious feeling); Dantian respiration (abdominal breathing which concentrates the consciousness in the hypogastrium); and abdomen muscle vibration respiration (respiration which has expiration which imitates a laugh by being divided into several short times); were examined for their effect on blood oxygen concentration, electric impedance of skin and pulse wave type. Furthermore, the change of the pulse wave was verified using fractal dimension analysis. This examination showed pulse wave type, neurometry value, and blood oxygen dissolution rate greatly changed by changing the breathing, and the possibility of influencing other organs was found.
