Introduction: Emerging renal support devices tend towards automated physiological monitoring and treatment adaptation. In the patient-centred development of the mobile NEPHRON+ system decisive physiological aspects and their mutual affections were identified and methods of measurement were incorporated into a wearable system enabling a personalized and un-supervised auto-adaptive treatment. Methods: Nephrologists determined the physiological variables to be monitored in dialysis patients. The experts' opinions were confirmed by extensive literature survey to find formalized relationships between the physiological parameters. As a basis for the embedded device control, suitable means of monitoring were integrated into the prototype of NEPHRON+, a networked mobile dialysis system. Results: To monitor the principal function of the blood cleansing device, ion selective and enzymatic electrodes tailored towards the miniaturized device are integrated in the mobile blood treatment system. Weight measurements are transmitted via Bluetooth to gauge the hydration surplus to be removed. Both, fluidic and chemical dynamics in the body are described based on the measurements using compartment models. Hemodynamic instabilities frequently arise during blood cleansing treatment due to homeostatic imbalance. Thus an electric sphygmomanometer and heart rate acquisition are likewise connected for intermittent measurements. To interpret these context sensitive parameters an accelerometer is embodied into the wearable system enabling to estimate the influence of the treated patient's physical activity on aforementioned vital parameters. This allows differentiating between the vital parameter dynamics arising from activity and the negative influence of homeostatic imbalance. Conclusion: A prototypic architecture for a defined treatment scenario has been realized to demonstrate the technical feasibility, enabling comprehensive physiological monitoring of dialysis treatments. Mathematical models of the monitored variables were gleaned for context aware evaluation of the mutually dependent parameters.

Non-invasive assessment of arterial oxygen saturation has traditionally been entrusted to pulse oximetry. Whereas commercial probes are confined to the finger tip or the forehead, several recent works aim at enlarging the range of placement sites. In the context of the development of a continuous multi-parameter health monitoring system, CSEM is exploring the reliability of pulse oximetry measurements at the sternum. This talk will address both theoretical and practical aspects of the development of such a sensor with special emphasis on the reliability of the measurement. Experimental data obtained from a novel eight channels sensor will be presented.

“…To be successful, these systems must be convenient to the end user: as they are permanently carried, they must be light, unobtrusive and comfortable. To reduce obtrusiveness, CSEM has developed a system using only four contact points with the body for a European Space Agency program on continuous multiparameter health monitoring system [4]. Multiple physiological parameters are measured at each point of contact, and signal processing algorithms running on the sensors can estimate oxygen saturation (SpO2), blood pressure (without cuff), core body temperature, respiration, electrocardiogram and activity.…”

New technologies can help to develop preventive healthcare, thereby leading to significant life quality improvements. Medical Body Area Networks are expected to become a key element in tomorrow's medical IT infrastructure by enabling the long term collection and analysis of health parameters. For this vision to become a reality, several challenges must be addressed. This work focuses on the technological aspects of ultra low power consumption, low latency and packet error rate. We consider and evaluate state of the art technologies currently under evaluation by the IEEE Standard Association 802.15.6 task group on body area networks, using detailed network simulation models, which have been calibrated with hardware measurements whenever possible and with MATLAB communication link simulations otherwise. We observe that the expected power consumption levels are similar for all considered platforms, and that they are determined mainly by the medium access control protocol. Trade-offs between communications latency, throughput and power consumption are identified. The performance of the Ultra Wideband Impulse Radio system is clearly impacted by its lack of carrier sensing capability. We conclude that the existing technologies are mature enough and that the remaing obstacles to widespread adoption are organizational and societal.
