The LifeGuard wearable monitoring system (CPOD) was developed and tested to continuously record multiple physiologic parameters, including ECG and blood pressure, over a 9-hour period.
The LifeGuard system provides a novel, unobtrusive wearable monitor for continuous multiparameter physiologic data collection in space and terrestrial applications.
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.
Mundt et al. (Thu,) conducted a other in Physiologic monitoring for space and terrestrial applications. LifeGuard multiparameter ambulatory physiologic monitoring system (CPOD) was evaluated on Device design, laboratory, and field testing. The LifeGuard wearable monitoring system (CPOD) was developed and tested to continuously record multiple physiologic parameters, including ECG and blood pressure, over a 9-hour period.
