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.
本文介绍了一种新颖、不引人注意且可穿戴的多参数动态生理监测系统，称为“生命卫士”（LifeGuard），适用于太空和地面应用。其核心部件是可穿戴监测器，即乘员生理观测装置（CPOD），它能够连续记录两条标准心电图导联、通过阻抗体积描记法测量的呼吸频率、心率、血红蛋白氧饱和度、环境温度或体温、三个加速度轴以及血压。这些参数可在9小时内以高保真度进行数字记录，并带有精确的时间戳和用户定义的事件标记。数据可通过内置的蓝牙射频链路连续传输到基站，或存储在32MB的板载闪存中，并使用串行端口下载到个人计算机。该设备由两节AAA电池供电。文中描述了可穿戴监测器的设计、实验室测试和现场测试情况。
