急诊重症监护病房噪音水平现状调查与分析

Investigation and Analysis of the Current Situation of the Noise Level in the Emergency Intensive Care Unit

目的:对急诊重症监护病房(EICU)的噪音水平进行调查分析,查找噪音分布的主要时段及来源,为制定有效的措施提供依据。方法:参考世界卫生组织(WHO)建议的关于医院平均噪音水平,运用声音强度监测仪(SW-525B分贝仪)监测各时段EICU噪音水平并记录,分析噪音来源。结果:EICU监测到的噪音平均值为:日间噪音平均值46.7~67.3 d B,夜间噪音平均值38.7~52.4 d B。噪音主要来源于仪器设备报警声、医护人员日常操作、医护沟通、家属探视交谈及周围环境噪音。结论:EICU噪音水平远超过WHO建议水平,制定降低噪音的措施刻不容缓。

Objective： To investigate the noise level of emergency intensive care unit（EICU）, find out the main periods and sources of noise distribution, and provide the basis for effective measures. Methods： According to the average hospital sound level recommended by the World Health Organization（WHO）, the sound level of EICU was monitored and recorded by sound intensity monitor（SW-525 B decibel meter）, and then noise sources were explored. Results： The mean values of noise monitored by EICU were as follows：average daytime noise was 46.7-67.3 d B and average night noise was 38.7-52.4 d B; the sources of noise mainly contianed alarm of equipment, daily operation of medical staff, medical communication, visiting conversation and ambient noise. Conclusion： The sound level of EICU far exceeds the level recommended by WHO, so it is urgent to formulate measures to reduce noise.
