A Measurement-Quality Body-Worn Physiological Monitor for Use in Harsh Environments

We describe the development and application of a body-worn data collection unit designed specifically for continuous long-duration recording of physical activity and electrocardiograms of extreme athletes and explorers in very harsh environmental conditions. These ruggedized body-worn units produce measured data of high amplitude and temporal resolution such that the post-processed data can be used for the analysis and assessment of the effects of extreme physical stress on these individuals, including cold conditions and high altitude effects. We will describe the approach employed in the development of these units, including design and assembly methods, and initial results recorded from researchers and from professional mountain climbers in acclimation and ascent of Mount Everest during Spring 2012.
