1、呼吸内科病区噪声的监测与分析[摘要]目的了解呼吸内科病区的噪声状况,为控制病房噪声,采取干预措施提供参考。方法应用噪声测量仪连续动态测量呼吸内科病区72h的每小时等效声级、最大声级、最小声级及各种噪声源的A声级。结果呼吸内科病区昼间与夜间噪声强度都超过规定标准,其中护士站的等效声级高于病房,差异有统计学意义(P<0.05)o交流说话声、呼叫声、电视机及收音机播放声、吸痰声、输液架及床护栏碰撞声等噪声源均超过80dB,成为呼吸内科病区的主要噪声来源。在设置相同床位数的基础上,有危重患者的病房噪声水平高于无危重患者的病房;在普通病房中,3人间、4人间病房的噪声水
2、平高于2人间,差异有统计学意义(P<0.05)o结论呼吸内科病区的噪声水平超过我国和WHO规定的标准,存在有多种来源的噪声。护士站、危重患者和床位数设置较多的病房应作为噪声控制的重点对象。[关键词]呼吸内科;噪声;监测[中图分类号]R473.5[文献标识码]A[文章编号]1673-7210(2014)04(a)-0083-04InvestigationandanalysisofnoiseinRespiratoryMedicalWardRONGGennanDepartmentofNursing,HuashanHospitalBaoshanBranchAffil
