A regular and chaotic dynamics of the modified model for interaction of cardiac and respiratory systems

Acoustic bulletin, Vol. 14 ¹ 4, (2011) p. 27-36
A model for interaction of the cardiovascular and respiratory systems is investigated with the allowance of feedback influence of heart dynamics on the parameters of respiratory oscillations. A linear approximation for the unknown feedback influence functions is considered. The respiratory tract was modeled by by the self-oscillating system under the impulsive influence of heartbeat. The steady-state regimes of the modified models are investigated by methods of the modern nonlinear dynamics. The regular (periodic and quasi-periodic) and chaotic regimes typical for functioning of the cardiosystem are found.
