The Accurate Assessment of Hemorrhage in the Field Using Similarity Based Modeling

Wegerich, Ryan, C. Richards, Hinojosa-Laborde, Convertino, Gould

Accurate and early assessment of hemorrhage in the field is essential for the initiation of optimal prehospital care. At present this is done using clinical signs and symptoms. Stroke volume (SV) is a primary indicator of the degree of central blood volume, but measurement is not feasible in the field. The purpose of this study was to assess the efficacy of similarity based modeling (SBM) in predicting SV based on data collected from a noninvasive wearable sensing device.
