摘要
该文针对多参数监护仪的各个参数在日常检定时,能得到更加准确可靠的测量数据,从A类不确定度测量重复性及被检设备分辨力,与B类不确定度测量标准器准确度等不确定度分量去分析,结果得出各个相关参数的测量不确定度,电压2.6%、扫描速度1.3%、幅频特性2.9%、心率、脉率、呼吸率均为1.3次/min、压力1.2mmHg、呼末二氧化碳浓度1.1mmHg,可供从事多参数监护仪检定人员参考。
In this paper,more accurate and reliable measurement data can be obtained for each parameter of the multi-parameter monitor during daily verification,and the uncertainty components such as the repeatability of class A uncertainty measurement and the resolution of the tested equipment,and the accuracy of class B uncertainty measurement standard,the measurement uncertainty of each related parameter is obtained,such as voltage 2.6%,scanning speed 1.3%,amplitude-frequency characteristic 2.9%,heart rate,pulse rate,and respiration rate are 1.3 beats/min,and pressure 1.2mmHg,end-tidal carbon dioxide concentration 1.1mmHg,which can be used as a reference for personnel engaged in multi-parameter monitor verification.
