Extensive research is being conducted to study the mechanism of blood flow during cardiopulmonary resuscitation (CPR). Recently, work has been published using a simple electrical model of the circulation to simulate the hemodynamics of CPR. This analog was a hard-wired circuit consisting of the heart and great vessels modeled as a resistive-capacitive network, pressure as voltage, blood flow as current, blood inertia as inductance and vascular valves as diodes. Such a model is useful for examining the physiology of various methods and techniques of CPR administration. In this investigation, a general purpose circuit simulation program, SPICE Version 2G.6, was used to analyze previously published CPR models. With minor modifications, the program was fully able to simulate the hard-wired circuits. The program is very flexible, allowing for easy model modification and a wide range of parameter values. In addition, the program offers the advantages of increased accuracy and low cost. Suggested future applications are for rapid evaluation of new CPR concepts.
目前正在进行广泛的研究,以探讨心肺复苏术(CPR)期间的血流机制。最近,已有研究利用一个简单的循环电学模型来模拟心肺复苏术的血流动力学。该模拟模型是一个硬连线电路,其中心脏和大血管被建模为一个电阻 - 电容网络,压力为电压,血流为电流,血液惯性为电感,血管瓣膜为二极管。这样的模型有助于研究各种心肺复苏术实施方法和技术的生理学原理。在本研究中,使用了通用电路仿真程序SPICE Version 2G.6来分析先前发表的心肺复苏术模型。只需进行少量修改,该程序就能完全模拟硬连线电路。该程序非常灵活,便于修改模型并设置广泛的参数值。此外,该程序还具有提高准确性和低成本的优点。建议未来将其应用于快速评估新的心肺复苏术概念。
