[Stereometric model of respiration with diaphragm electrostimulation].

A stereometric model of respiration has been proposed, which is based on the approximation of the surface of the chest and that of the diaphragm by the well-known mathematical functions, which generally calculates the value of respiratory volume as a function of geometric parameters such as the circumference of the chest and torso, the distance between the thoracic vertebrae. The derived formulas may be used as a background material for designing the feedback systems by the respiratory volume in order to maximally approach the electrically stimulated respiration to physiological respiration.
