A Cardiovascular Simulator for Research

We introduce here the Research CardioVascular SIMulator (RCVSIM) software in order to complement research with the experimental data sets provided by PhysioBank. The human cardiovascular model upon which RCVSIM is based includes three major components. The first component is a lumped parameter model of the pulsatile heart and circulation. The second component is a short-term regulatory system model which includes an arterial baroreflex system, a cardiopulmonary baroreflex system, and a direct neural coupling mechanism between respiration and heart rate.

本节旨在引入研究心血管模拟器（Research CardioVascular SIMulator，简称RCVSIM）软件，旨在借助PhysioBank提供的实验数据集，丰富研究内容。RCVSIM所依托的人类心血管模型由三大主要部分构成。首部分为脉动心脏及循环的集中参数模型。次部分为短期调节系统模型，该模型涵盖了动脉压力感受器反射系统、心肺压力感受器反射系统以及呼吸与心率之间的直接神经耦合机制。
