We report on the feasibility of standing ballistocardiogram (BCG) measurements recorded in a microgravity environment. A clinically-tested BCG monitoring scale was adapted for parabolic flight for the microgravity measurements. Upon completion of this flight campaign, the BCG scale was shown to make measurements in micro-g and one-g environments--which is a first demonstration for a standing BCG system. This screening experiment demonstrated proof-of-concept attributes of the hardware design necessary for future characterization studies with multiple subjects. This scale-based BCG system is proposed as a practical device for hemodynamic monitoring for astronauts in Earth, Lunar, Martian, orbital, and interplanetary environments.
我们报告了在微重力环境下进行站立式心冲击图（BCG）测量的可行性。一种经过临床测试的BCG监测仪被改装用于抛物线飞行以进行微重力测量。在这次飞行任务完成后，该BCG监测仪被证明能够在微重力和1g重力环境下进行测量——这是站立式BCG系统的首次展示。这次筛选实验证明了未来对多个受试者进行特征研究所需硬件设计的概念验证属性。这种基于监测仪的BCG系统被提议作为一种实用设备，用于在地球、月球、火星、轨道和星际环境中对宇航员进行血液动力学监测。
