AI Technical Summary

Technical Problem

Existing methods for deploying automated external defibrillators (AEDs) fail to accurately reflect the varying emergency needs of aging communities, resulting in insufficient deployment in high-risk communities and redundant deployment in low-risk communities. Consequently, the efficiency of emergency resources is low, and there is a lack of technical solutions to translate community-specific risk thresholds into AED service response radius.

Method used

By constructing a community cardiovascular event risk prediction model, extracting key influencing features and generating community-specific risk thresholds, and combining a multi-scenario traffic impedance surface to construct an AED accessibility evaluation model, the accessibility of AEDs in each community is calculated, and multi-objective optimization is carried out to obtain an optimized layout scheme.

Benefits of technology

This improved the alignment between AED deployment and the actual conditions of the community, enhancing emergency response efficiency, fairness of deployment, and resource utilization efficiency within the target area.

Abstract

The invention discloses a community-scale automatic external defibrillator layout optimization method and related equipment, which can be applied to the technical field of public health facility configuration and urban emergency resource optimization. The community cardiovascular event risk prediction model is constructed after the research database used for AED optimization layout in the target area is obtained, the key influence features and the community specificity risk threshold are extracted, and then the community specificity AED service response radius is generated. Meanwhile, a multi-scene traffic impedance surface and an AED reachability evaluation model are constructed according to a research database, and after the AED reachability of each community is calculated, the AED reachability is coupled with a community specific risk to obtain a to-be-optimized AED layout scheme, and then multi-target optimization is performed to obtain a target AED optimized layout scheme; therefore, the AED facility service range in the target area can better fit the real risk and travel capability difference of the community, and the first-aid response efficiency, the layout fairness and the resource utilization efficiency in the target area are improved.
