Current quantitative descriptions of the cardiovascular system in hemorrhagic shock focus on pressure based metrics. This approach is often incomplete; overlooking the important role of tissue perfusion. Electrical analogs to the cardiovascular system may offer a more complete description of hemorrhage. Application of fundamental concepts in electrical circuit theory (i.e.; Kirchhoff's Voltage Law and Ohm's Law) to analogs of the cardiovascular system offers a more refined description of this complex process. This manuscript hopes to serve as a starting point for a more mathematically robust, and clinically relevant description of hemorrhagic shock.
目前，失血性休克中心血管系统的定量描述侧重于基于压力的指标。这种方法往往不完整，忽略了组织灌注的重要作用。心血管系统的电气模拟可能提供对出血的更完整描述。将电路理论中的基本概念（即基尔霍夫电压定律和欧姆定律）应用于心血管系统的模拟，为这一复杂过程提供了更精细的描述。本文希望为更具数学稳健性和更具临床相关性的失血性休克描述提供一个起点。
