Pulse: A Context-Aware Blood Donation and Emergency Response System
Blood donation plays a crucial role in saving lives during medical emergencies, yet traditional blood bank systems suffer from inefficiencies such as manual donor discovery, lack of real-time communication, and absence of donor safety enforcement. In emergency scenarios, delays in locating compatible donors during the critical “Golden Hour” significantly impact patient survival. This paper presents Pulse, a modern web-based Blood Donation and Emergency Finder System designed to address these limitations. The system integrates a context-aware smart matching algorithm, secure authentication mechanisms, and automated donor safety protocols. Pulse uses a decoupled architecture with React.js frontend and FastAPI backend, ensuring scalability and high performance. A key innovation of the system is the implementation of a 56- day automated cooldown protocol, which prevents unsafe repeated donations. Additionally, the platform provides real-time inventory tracking and centralized administrative control. The proposed system improves emergency response time, ensures donor safety, and enhances healthcare logistics efficiency.
