Abstract

Seismocardiogram (SCG) is proposed in this study to be used for earlier detection of hemorrhage and lower body negative pressure (LBNP) was used to create a hemodynamic response similar to hemorrhage. Echocardiogram measurements showed a maximal reduction of 23% in cardiac output. Analysis of left ventricular ejection time (LVET), derived from a seismocardiogram (SCG), demonstrated to be more sensitive in detection of early stage hemorrhage compared to pulse pressure and heart rate. LVET was significantly different between different stages of LBNP for thirty two subjects.
