Sonification and Multiple-Patient Monitoring

医疗设备上的听觉警报是为了挽救生命。但是，如果有太多烦人的警报，工作人员对所有警报都没有反应：这就是“警报疲劳”。警报疲劳可能导致患者伤害甚至死亡，特别是如果工作人员必须将注意力分散在多个患者身上。该项目表明，一种称为声化的听觉显示形式可能会扩展到多个病人的监护。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声处理。它还测试了头戴式显示单元是否可以帮助工作人员在多个患者之间有效地定位听觉注意力，而不会分散当前任务的注意力。结果将为警报疲劳提供解决方案。

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.
