Key result
An observer-based state and fault estimation method using a four-element windkessel model successfully estimated systemic pressure and aortic blood flow in numerical simulations.
A four-element windkessel model in singular state-space form can be used to design an observer for monitoring systemic pressure and aortic blood flow in numerical simulations.
May aid CV monitoring in simulations; leaves open prospective clinical validation.
An observer-based state and fault estimation method for the cardiovascular system is presented in this brief. The approach is based on the use of a four-element windkessel model which is written in a singular state-space form. This particular representation allows to design an observer to estimate the systemic pressure, the aortic blood flow, and possible problems in the flow through the aorta for monitoring purposes. Numerical simulations are performed in order to demonstrate the pertinence of this representation to conceive an adequate observer to monitor the cardiovascular activity.
