Optimization proposal of a standard-based patient monitoring platform for ubiquitous environments

This article describes the optimization of a patient telemonitoring platform based on the ISO/IEEE11073 (X73) standard to enable medical device interoperability. In order to achieve this, principal advantages and remaining improvements are evaluated to include in further upgrades towards the new profile evolution, oriented to ubiquitous environments and wearable devices (Personal Health Devices, X73-PHD), and opened to additional plug-and-play features and remote management. After evaluating the possibilities, we describe the platform porting process, a required step to adapt it to the new functionalities and allowing the development of end-to-end standard based systems. The paper details the implementation of the agent-manager architecture, particularized on the X73-PHD communication protocol between a Medical Device (MD) and a central gateway (Compute Engine, CE). Lastly, the obtained results are evaluated, oriented to constitute an X73-PHD tester to prove the challenges currently under discussion in the European Standardization Committee (CEN).
