I-Corps: A Rapid Pulse Confirmation Device for Cardiopulmonary Resuscitation

I-Corps项目的更广泛影响/商业潜力是开发技术，以协助公众、军队、急救人员和医疗专业人员进行心肺复苏（CPR）。25年来，心肺复苏术中胸部按压的指导方针一直依赖于将骤停患者的胸部按压一定的英寸，并用肉眼测量这个深度。目标是通过提供易于使用的技术来改进这些指导方针，这些技术可以指导救援人员并提供有关其心肺复苏表现的实时反馈。通过改进关键性能指标，所提出的技术可以提高医院内外心脏骤停的生存率。这个I-Corps项目是基于超声技术的发展，该技术已被简化，专门用于检测心肺复苏（CPR）期间的血流。通过跟踪目标血管的血流，该技术旨在为用户提供具体的指令和有关心肺复苏术表现的实时指标。目的是改善胸部按压，这可能会导致更多的血液流动和氧气输送到大脑、心脏和其他重要器官。这项提议的技术已经通过初步的试点研究得到了验证，该研究旨在将提议的技术与目前在受控心脏骤停期间进行的侵入性血压监测进行比较。未来的发展可能会完善该技术的重点和功能。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this I-Corps project is the development of technology to assist the general public, military, first responders, and medical professionals with cardiopulmonary resuscitation (CPR). For over 25 years, guidelines for chest compressions during CPR have relied on compressing an arrest victim’s chest a set amount of inches and gauging this depth by the naked eye. The goal is to sharpen these guidelines by making available easy-to-use technology that guides the rescuer and provides real-time feedback about their CPR performance. By improving critical performance metrics, the proposed technology may improve survival of cardiac arrest both in and out of the hospital. This I-Corps project is based on the development of ultrasound technology that has been streamlined and specifically purposed to detect blood flow during cardiopulmonary resuscitation (CPR). By tracking blood flow through target blood vessels, the proposed technology is designed to provide users with specific instructions and real-time metrics about the performance of their CPR. The goal is to improve chest compressions, which may lead to greater blood flow and oxygen delivery to the brain, heart, and other vital organs. The proposed technology has been validated by initial pilot studies aimed at comparing the proposed technology to the current invasive blood pressure monitoring during controlled cardiac arrest. Future development may improve the focus and function of the technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
