Brain Trauma Assessment System

Active Signal Technologies建议进一步开发和实地测试其创新的手持式脑外伤评估系统（BTAS），目的是使EMS提供者能够以足够的灵敏度直接测量脑病理，从而自信地对患者进行分诊。根据目前的现场协议，准确诊断创伤性脑损伤（TBI）是困难的。通过减少误诊，BTAS将减少不必要的送往创伤中心的运输，并将允许更及时，更关键的治疗合法的TBI，希望减少死亡和严重伤害。I期试验表明，与目前的格拉斯哥昏迷量表不同，pda宿主、非侵入性、被动声学监测系统可以准确区分意识受损患者的早期TBI与其他非威胁性头部损伤以及酒精和药物损伤。Active Signal的目标是：1)改进和简化BTAS

Active Signal Technologies proposes to further develop and field-test its innovative hand-held Brain Trauma Assessment System (BTAS) with the objective of equipping EMS providers to directly measure brain pathology with sufficient sensitivity to confidently triage patients. With current field protocol, accurate diagnosis of traumatic brain injury (TBI) is difficult. BTAS through decreasing misdiagnosis will reduce unnecessary transports to trauma centers and will allow more timely, critical treatment of legitimate TBI's, hopefully diminishing death and serious injury from this significant came. Phase I demonstrated that, unlike the current Glasgow Coma Scale, a PDA-hosted, non-invasive, passive acoustic monitoring system can accurately distinguish early-stage TBI in patients with impaired consciousness from other non-threatening head insults and from alcohol and drug impairment. Active Signal aims to: 1) improve and simplify BTAS hardware for enabling access to a broader patient cross section, and 2) expand BTAS field evaluation from 15 to 150 patients with impaired consciousness, establishing the effectiveness of this assessment technique over a broad cross section of injury conditions in the very early stages of brain injury. The approach will include wireless sensors, push-button interface, increased monitoring stations, and a widely expanded field monitoring staff.
