All clinical alarms require nurses to respond even if an intervention is not needed. Nurses are expected to respond appropriately to each alarm and establish priorities among their care practices accordingly. This study was conducted to examine the number and types of clinical device alarms used in intensive care units, the duration of their activation, and nurses' degree of sensitivity to them.
This observational study was conducted in 4 intensive care units in a university hospital in Turkey. A total of 20 nurses (5 from each unit) were observed for a total of 80 hours. The alarms were categorized as valid, false, or technical.
During the study observation period, the mean number of alarms sounding per hour per bed was 1.8. A total of 144 alarms were recorded, of which 70.8% were valid, 15.3% were false, and 13.9% were technical. The mean duration of alarm activation was 8 minutes for valid alarms, 14 minutes for false alarms, and 53 minutes for technical alarms.
Nurses' responses to alarms differ depending on alarm type; for alarms that do not require an emergency intervention, nurses tend to respond late or not at all.
所有临床警报都需要护士进行响应，即使不需要干预。护士需要对每个警报做出适当的反应，并根据护理实践确定优先级。本研究旨在调查重症监护病房中使用的临床设备警报的数量和类型、其激活的持续时间以及护士对它们的敏感程度。
本观察性研究在土耳其一所大学医院的 4 个重症监护病房进行。共有 20 名护士（每个病房 5 名）观察了总共 80 小时。警报被分为有效、虚假和技术。
在研究观察期间，每小时每张床发出的警报数平均为 1.8。共记录了 144 个警报，其中 70.8%是有效的，15.3%是虚假的，13.9%是技术的。有效警报的激活时间平均为 8 分钟，虚假警报为 14 分钟，技术警报为 53 分钟。
护士对警报的反应因警报类型而异；对于不需要紧急干预的警报，护士往往会延迟或根本不响应。
