Abstract

The article deals with nonlinear dynamic model on the basis of method algorithm Non-Linear Auto-Regressive Moving Average with Exogenous Inputs [1], which connects interaction measurements results of the human respiratory and cardiac systems. Application of this model is shown for description of these processes and their interconnection demonstrating how human inhalation and exhalation correlate with cardiac cycle. The model is used for both separate description of breathing and tachycardia processes and their interconnection. This model is suggested for the compressed general description of human organism functioning features and for description of concrete person features. Filtering application of the joint model for breathing and tachycardia according to the given method makes it possible to decompose obtained model to independent initial models.
