This paper, focusing on the growing need for rescue operations worldwide, proposes a knowledge graph-based AI system for rapid and optimized medical services in emergency situations. To address the challenges faced by emergency responders and medical professionals who must accurately assess a patient's condition and provide appropriate treatment within a limited timeframe, we present a knowledge management system centered on a knowledge graph that provides on-site, on-site knowledge that is immediately calculated, evaluated, and processed. This system utilizes AI-based situational awareness to provide intelligent treatment recommendations.
