초록

최근 병원 밖 심정지 환자의 생존율 향상을 위한 일반인 대상 심폐소생술 교육의 중요성이 강조되고 있다. 일반인 대상 효과적인 심폐소생술 교육을 위해 보다 정확하고 생동감 있는 교육전략이 필요하다. 이에 본 연구에서는 확장현실 기반의 심폐소생술 교육시스템을 개발하고 일반인을 대상으로 교육한 사용성 평가 결과를 제시한다. 3개의 응용프로그램으로 구성된 확장현실 기반 심폐소생술 교육시스템에서는 첫 번째 마네킹에 정합된 3D 심장 해부도를 스마트글라스에 전송하여 가슴압박 지점을 안내한다. 두 번째 응용프로그램은 스마트글라스를 통해 심폐소생술 과정에 대한 시·청각적 정보를 제공함과 동시에 스마트워치의 진동 알림을 전송하여 심폐소생술의 정확한 압박 속도를 안내한다. 세번째 Add on kit는 마네킹에 설치된 센서를 통하여 흉부 압박의 깊이와 속도에 대한 즉각적인 피드백 정보를 스마트폰으로 전송한다. 본 연구에 참여한 93명의 대상자는 확장현실 기반 심폐소생술 교육시스템이 현장감과 효과성 측면에서 긍정적이라 평가하였다. 확장현실 기술을 이용한 정합기술은 현장감과 몰입도를 높이고 자기 주도적 훈련을 쉽게 함으로서 심폐소생술 교육 운영 효율성 향상에 이바지할 수 있다.

Recently, the importance of CPR training for the layperson has been emphasized to improve the survival rate of out-of-hospital cardiac arrest patients. An accurate and realistic training strategy is required for the CPR training effect for laypersons. In this study, we develop an extended reality (XR) based CPR training system and evaluate its usability. The XR based CPR training system consisted of three applications. First, a 3D heart anatomy image registered to the manikin is transmitted to the smart glasses to guide the chest compression point. The second application provides visual and auditory information about the CPR process through smart glasses. At the same time, the smartwatch sends a vibration notification to guide the compression rate. The 'Add-on-kit' is a device that detects the depth and speed of chest compression via sensors installed on the manikin and sends immediate feedback to the smartphone. One hundred laypersons who participated in this study agreed that the XR based CPR training system has realism and effectiveness. XR based registration technology will contribute to improving the efficiency of CPR training by enhancing realism, immersion, and self-directed learning.
