Advances in information and communication technologies, ICT, are bringing new opportunities in the field of middleware systems oriented to ubiquitous environments and wearable devices used for patient telemonitoring. At a time of such challenges, this paper arises from the need to identify robust technical telemonitoring solutions that are both open and(More)
In this work, a novel ambulatory ECG monitoring device developed in-house called HOLTIN is analyzed when operating in complex indoor scenarios. The HOLTIN system is described, from the technological platform level to its functional model. In addition, by using in-house 3D ray launching simulation code, the wireless channel behavior, which enables ubiquitous(More)
A proof-of-concept design of a patient monitoring solution for intensive care unit environments has been presented. It is end-to-end standard-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an electronic health-care record (EHR) server. At the bedside end, the system is a plug-and-play sensor(More)
This paper explains the challenges encountered during the ISO/IEEE 11073 standard implementation process. The complexity of the standard and the consequent heavy requirements, which have not encouraged software engineers to adopt the standard. The developing complexity evaluation drives us to propose two possible implementation strategies that cover almost(More)
The ISO/IEEE 11073 (x73) family of standards is a reference frame for medical device interoperability. A draft for an ECG device specialization (ISO/IEEE 11073-10406-d02) has already been presented to the Personal Health Device (PHD) Working Group, and the Standard Communications Protocol for Computer-Assisted ElectroCardioGraphy (SCP-ECG) Standard for(More)
Traditionally, e-Health solutions were located at the point of care (PoC), while the new ubiquitous user-centered paradigm draws on standard-based personal health devices (PHDs). Such devices place strict constraints on computation and battery efficiency that encouraged the International Organization for Standardization/IEEE11073 (X73) standard for medical(More)
This paper presents a novel implementation methodology of ISO/IEEE11073 standards for use in real monitoring platforms based on patterns paradigm. These monitoring platforms include several medical devices based on low voltage-low power microprocessors. As a proof of the concept, INTENSA project which aims to develop and evaluate a heart failure follow-up(More)
There is a need to develop open sensors and middleware components that allow transparent integration and plug-and-play interoperability of Medical Devices (MDs) and Computer Engines (CEs). The use of standards seems to be the internationally adopted way to solve these problems and allow implementing ubiquitous solutions, including wearable devices, focused(More)
Standardized exchange of clinical information is a key factor in the provision of high quality health care systems. In this context, the openEHR specification facilitates the management of health data in electronic health records (EHRs), while the ISO/IEEE11073 (also referred to as X73PHD) family of standards provides a reference framework for medical(More)
Most healthcare services use information and communication technologies to reduce and redistribute the workload associated with follow-up of chronic conditions. However, the lack of normalization of the information handled in and exchanged between such services hinders the scalability and extendibility. The use of medical standards for modelling and(More)
