A Multiparameter Wearable Physiologic Monitoring System for Space and Terrestrial Applications

Abstract

A novel, unobtrusive and wearable, multiparameter ambulatory physiologic monitoring system for space and terrestrial applications, termed LifeGuard, is presented. The core element is a wearable monitor, the crew physiologic observation device (CPOD), that provides the capability to continuously record two standard electrocardiogram leads, respiration rate via impedance plethysmography, heart rate, hemoglobin oxygen saturation, ambient or body temperature, three axes of acceleration, and blood pressure. These parameters can be digitally recorded with high fidelity over a 9-h period with precise time stamps and user-defined event markers. Data can be continuously streamed to a base station using a built-in Bluetooth RF link or stored in 32 MB of on-board flash memory and downloaded to a personal computer using a serial port. The device is powered by two AAA batteries. The design, laboratory, and field testing of the wearable monitors are described.

Adaptive motion artefact reduction in respiration and ECG signals for wearable healthcare monitoring systems

“…Physiological and psychological data acquired in real life by wearable systems can enable early detection of diseases, reveal correlations between lifestyle and health, and bring healthcare to remote locations and resource-poor settings [31,36,43]. In situations where workers are exposed to extreme conditions, dangers or hazards, employing wearable technology can help monitor their vital signs and save their lives [24,32,43]. In sports medicine, likewise, unobtrusive wearable sensors can be used to capture physiological data and physical movements of multiple people in real time for the purposes of analysis and performance evaluation [6,7].…”

The Impact of Information Quality on Quality of Life: An Information Quality Oriented Framework

“…This means that different types of lifelog data can be acquired but such systems are expensive. Wearable sensing platforms [42] use sensors such as EEG and ECG which are attached to the body to measure brain activity and heart-rate and are cheap and light weight [43]. These technologies and devices described here, while contributing to QOL for the elderly have also contributed to the "Big-Data Tsunami".…”

“…Among those technologies, the portable heart rate monitors are widely used. In such portable devices, the low power consumption and the small physical size are very important [1][2][3]. In order to measure the heart rate without disturbing the normal life, the portable device should have a small size and a light weight.…”
