Instant expertise for novice responders performing cardiopulmonary resuscitation (CPR)

摘要

More than 300,000 people die from sudden cardiac arrest (SCA) annually in the United States. As professional responders such as EMTs make efforts to expedite their arrival, critical minutes pass jeopardizing the victim’s health. Providing life-sustaining intervention in the first few minutes greatly contributes to healthier outcomes. Often, there are witnesses to SCA events that could respond immediately, but they are incapable of providing treatment. The just-in-time support (JITS) approach aims to assist novice operators in completing unpracticed tasks such as cardiopulmonary resuscitation (CPR) at the moment of need. By providing na?ve users plans, cues, and feedback, JITS systems facilitate goal accomplishment. The results of this work suggest a JITS device could empower novice responders with CPR capabilities. Widespread deployment of such a device could greatly decrease response time and save lives.
