Developing a Pulse Wave Model Using the Lumped-Element Method

Cardiovascular diseases have a huge tendency to develop and there is a need to develop new diagnostic methods and accurate measurement of blood pressure. Research in the field of pulse wave showed reproducibility of results for assessing the state of the vascular bed by assessing the speed of propagation of the pulse wave, and the correlation of the pulse wave with changes in blood pressure parameters was proved. Modeling a pulse wave, in particular, of the brachial artery allows you to immerse yourself in the process of physiological transmission of parameters from the artery to external structures (for example, a cuff). Modeling using the RLC parameters of the electronic circuit has proven itself due to the possibility of a multi-segment description of the state of the vascular bed, the realistic calculations of the parameters of the electronic circuit, and the established correspondence between the parameters of the electronic circuit and the physiological parameters of hemodynamics.
