科学领域:

  • 医学技术 医学技术 医学技术
  • 人与计算机的互动.
  • 临床信息学是一种临床信息学.

背景情况:

  • 重症监护室 (ICU) 的临床医生面临着每天超过900个警报的感官过载,导致反应延迟和错误.
  • 整合生命体征的基于对象的视觉显示显示显示出比标准ICU报警更快,更准确的响应.

研究的目的:

  • 设计和评估一种基于环的新型视觉报警系统,将心率 (HR),血压 (BP) 和外周氧和 (SpO2) 整合在一起.
  • 通过使用虚拟现实 (VR) 测试环境进行可控和可复制的评估来评估系统的有效性.

主要方法:

  • 在VR环境中,使用HTC VIVE Pro Eye耳机将基于环的显示器与先前验证的基于图形的显示器进行了比较.
  • 测量了参与者识别模拟临床事件的速度和准确性,使用头部定向软件跟踪显示焦点.

主要成果:

  • 基于环的显示显示显示了33%的更高准确度和1.00秒更快的平均响应时间,而不是单独显示的基于图表的显示.
  • 当两种显示器都被介绍时,参与者在82.2%的时间内查看了基于戒指的显示器,表明了偏好和注意力.

结论:

  • 基于环形的视觉报警系统显著提高了报警识别的准确性,并减少了相比基于图表的显示器的响应时间.
  • 虚拟现实为测试和评估医疗接口提供了一个强大的平台.
  • 未来的研究应该包括眼睛跟踪和开发多感官报警系统.
