The article proposes a multiple-feedback loop model to study the short-term autonomic control of the cardiovascular system using measured signals.
Variables involved in cardiovascular regulation, such as blood flow and pressure, oxygen concentration, are under the control of several feedback mechanisms with different dynamics. We are interested in the short-term control of blood flow and pressure by the autonomic nervous system through baroreceptor control loops. The aim of this article is to relate usually measured cardiovascular signals to models of the controlled cardiovascular system. A multiple-feedback loop organisation is obtained that can help to study the control function. Control assessment could use signal-based estimates of associated feedback sensitivities.
