Sonification and Multiple-Patient Monitoring

医疗设备上的听觉警报是为了拯救生命。不过，如果闹钟太多，员工就会对所有的闹钟都反应迟钝：这就是“闹钟疲劳症”。警报疲劳可能会导致患者受伤甚至死亡，特别是当工作人员必须将注意力分散到多个患者时。该项目推测，一种名为发声的听觉显示形式可能会扩展到多患者监护。在一系列的三项研究中，该项目将开发和测试用于远程监测多名患者的新型发声。它还测试了头戴式显示器是否可以帮助工作人员在不分散当前任务的情况下有效地将听觉注意力定向到多个患者身上。结果将为解决警报疲劳问题提供解决方案。

Auditory alarms on medical equipment are meant to save lives. If there are too many nuisance alarms, though, staff become unresponsive to all alarms: this is "alarm fatigue". Alarm fatigue can lead to patient harm or even death, particularly if staff must divide their attention across multiple patients. This project conjectures that a form of auditory display called sonification might be extended to multiple-patient monitoring. In a series of three studies this project will develop and test novel sonifications for remote monitoring of multiple patients. It also tests whether a head-worn display unit can help staff orient auditory attention effectively across multiple patients without distracting from current tasks. Outcomes will offer solutions to alarm fatigue.
