Timely access to compatible blood remains one of the most critical challenges in emergency healthcare management. In life-threatening situations such as accidents, surgeries, childbirth complications, and critical illnesses, delays in locating suitable blood donors can significantly increase mortality risk. Existing blood procurement mechanisms primarily rely on hospital blood banks, manual coordination, social media appeals, or informal intermediary networks. These approaches are often fragmented, time-consuming, geographically inefficient, and in some cases, financially exploitative. The absence of a structured, real-time communication framework between voluntary donors and recipients further exacerbates emergency response delays. This research presents the design and implementation of a Real-Time Blood Demand Tracking and Emergency Aid Management System, a web-based platform developed to establish a direct, transparent, and technology-driven connection between voluntary blood donors and patients in urgent need. The proposed system enables donors to register securely and maintain updated profiles containing essential attributes such as blood group, geographical location, availability status, and communication preferences. When a verified emergency blood request is generated, the system automatically identifies compatible donors within a defined geographic radius using location-based matching algorithms. Upon identification, automated SMS alerts are dispatched to eligible donors, providing essential details including the patient’s contact information and hospital location. This immediate notification mechanism significantly reduces response time and eliminates dependency on intermediaries. The system architecture integrates modern web technologies, including Angular for the front-end interface and Firebase for backend database management, authentication, and real-time data synchronization. The platform ensures scalability, data integrity, and secure information handling. By leveraging real-time communication and location intelligence, the proposed system enhances emergency responsiveness, promotes voluntary blood donation, and contributes to improved healthcare service delivery. The implementation demonstrates how digital transformation in healthcare can create a costeffective, reliable, and socially impactful solution to address urgent blood supply challenges.
