TLDR: The KIRETT project introduces a wrist-worn wearable device for rescue operators that integrates real-time vital signs data with a knowledge graph and artificial intelligence. This system provides intelligent decision support and treatment recommendations, helping health professionals make faster, more accurate decisions in critical, time-sensitive rescue scenarios. It streamlines data access, offers proactive alerts, and can even suggest or automate treatment steps, significantly improving situational awareness, resource allocation, and overall patient care.
In high-stakes environments like rescue operations, every second counts. Health professionals face immense pressure to make critical decisions quickly and accurately, often while dealing with rapidly changing patient conditions and a wealth of information from various sources. The KIRETT project emerges as a groundbreaking initiative designed to alleviate this pressure by integrating vital signs data with intelligent decision support, all delivered through a convenient wrist-worn wearable device.
Enhancing Decision-Making in Rescue Scenarios
The core challenge in emergency medicine is the need for optimal treatment under severe time constraints. Rescuers must synthesize patient history, vital signs, and external diagnoses to provide precise, patient-oriented care. The KIRETT project addresses this by providing context-based treatment recommendations and real-time vital signs integration, allowing rescue operators to maintain focus on the patient while receiving crucial information and suggestions.
Vital signs such as electrocardiogram (ECG), heart rate, blood pressure, and oxygen saturation are fundamental to medical assessment. KIRETT leverages these parameters to help narrow down possible remedies and monitor a patient’s health continuously. This real-time data empowers rescue personnel to adjust their decision-making on the fly, minimizing potential long-term damage from incorrect treatments.
The KIRETT Project: A Smart Wearable Solution
The KIRETT project aims to optimize time-critical treatments using modern technologies, specifically knowledge graph technologies and artificial intelligence, all housed within a mobile, wearable rescue platform powered by embedded systems. This wrist-worn device integrates medical data aggregation and processing with AI solutions for situation detection and procedural treatment recommendations. By utilizing a knowledge graph, KIRETT offers data-driven assistance that goes beyond basic patient monitoring, enabling health professionals to concentrate more effectively on immediate patient needs.
The system integrates modules for treatment recommendations, situation detection, data middleware, and embedded device utilization. The foundation for treatment recommendations is a knowledge graph, conceptualized for rescue scenarios and populated from official manuals and treatment requirements. These manuals explicitly incorporate vital signs for decision-making, including data thresholds and symptoms.
How Vital Signs Are Integrated
Currently, vital signs are recorded by rescue operators using integrated medical devices. While continuous monitoring devices provide real-time value variations, rescuers still need to analyze these values to identify abnormalities and observe changes. KIRETT streamlines this process by integrating vital signs directly into the knowledge graph, providing additional, tailored information for each step of treatment, improving overview and accessibility. This eliminates the need for rescuers to constantly check multiple external medical devices.
The integration workflow involves several key modules: the Graphical User Interface (GUI), the Graph component, and the Middleware. When a rescuer proceeds to a treatment step that requires vital signs, the GUI sends a request to the Graph component. The Graph queries its knowledge graph, built from rescue operation manuals, and identifies that patient vital signs are needed. It then sends a message to the Middleware component, which hosts the database and retrieves values from medically certified devices (like the ZOLL X-Series) via Bluetooth connection.
Once the Middleware acquires the vital signs, it returns them to the Graph component. Here, the data is organized and combined with other necessary information before being sent back to the GUI for display. This allows the KIRETT wearable to present the current treatment step alongside the relevant vital signs, complete with a timestamp for transparency. If a value is unavailable, the system indicates “unknown,” prompting rescuers to seek that information.

Intelligent Decision Support and Future Directions
Beyond simply displaying vital signs, KIRETT can provide intelligent indicators. The Graph component can assess whether a vital sign value falls within prescribed parameters or indicates a critical state, using color-coded text or warning pop-ups. This information can even lead to automated decisions, where the system suggests or implements a clear direction for a pending decision, with full transparency and the option for the rescuer to override it. This capability significantly speeds up decision processes and allows for faster patient treatment and quicker reactions to sudden changes.
The benefits of integrating vital signs data into knowledge graphs for rescue operations are substantial. They include a more complete picture of the patient’s condition, improved situational awareness, optimized resource allocation (especially in mass casualty incidents), enhanced communication and collaboration among medical staff, and data-driven decision-making. The adaptable structure of knowledge graphs also ensures the system can evolve and incorporate new data sources as technologies advance.
Looking ahead, the KIRETT project envisions further advancements, such as using machine learning algorithms and Bayesian networks to analyze treatment patterns and predict outcomes. An alarm notification system could alert rescuers to threshold violations, suggesting treatment path modifications based on historical data and expert feedback. Future work also includes investigating interoperability with other systems like Electronic Health Records (EHR) and conducting usability studies to refine the system in real-world scenarios. This continuous evolution promises to make rescue operations even more efficient and effective, ultimately saving more lives.
