An Integrated Simulation Platform for Cardiac Arrest Response System

In response to China's over 700,000 annual out-of-hospital cardiac arrests (OHCA), this paper presents a novel simulation framework integrating Geographic Information System, event occurrence probability models, and an agent-based model to efficiently formulate, optimize, simulate, verify, and analyze emergency response efficiency in cities. The framework supports large-scale, long-term city-level optimization and simulation, allowing for the evaluation of various dispatch algorithms, and deployment mechanisms. We offer insights into emergency first responder system design in Shenzhen, highlighting the significant impact of dispatch range, responder quantity, and skills ratio on survival rates. The experimental results indicate the maximum effective dispatch range of current dispatch strategy is 800 meters. As number of responders is less than 100, prioritizing an increase can significantly improve survival rates, with a maximum rise of 148%. However, when it exceeds 100, the focus should shift to augmenting the proportion of skilled responders, followed by the ratio of mobile responders.
