Hospital Patient Monitoring SDC Aggregator Approaches

This document is a technical report that discusses various approaches to the SDC (Service-oriented Device Connectivity) aggregator in the context of hospital patient monitoring. It outlines the challenges associated with integrating multiple medical devices, such as ventilators and infusion pumps, which often use legacy communication protocols. The report compares different strategies for managing device data through SDC gateways and aggregators, detailing the pros and cons of each approach. These include having one End-Point-Reference (EPR) per device, one EPR for all devices, and one EPR per system context. Each approach is evaluated based on factors like network connection management, data privacy, and the size of the Medical Device Information Base (MDIB). The report concludes with recommendations for selecting the appropriate approach based on the characteristics of the devices involved and their usage scenarios.
