The European Space Agency (ESA) commissioned CSEM to design, build, validate and deliver one fully operational ground prototype of a system (LTMS2) measuring physiological parameters. The system was shipped and will be used during 2008 at Concordia station (www.concordiastation.com) in Antarctica to study the physiological adaptation of crews to remote, isolated and extreme environments. The underlying...
When pulse oximetry is required at other body locations than the finger tip new strategies for optical setups and signal handling are required. In this paper we present a combination of short and long light paths that succeeded in resolving the problems associated to the development of a finger ring SpO2 sensor.
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...
Long-term monitoring of human vital signs is becoming one of the most important fields of applied research in biomedical engineering. In order to achieve weeks to months of monitoring, new strategies for sensing, conditioning, processing and communicating have to be developed. While it is relatively easy to monitor some medical parameters at rest, getting reliable measurements and diagnosis during...
