血液净化装置主要计量参数对临床影响的探讨

Clinical influence of main metrological parameters on hemofiltration equipment

针对血液净化装置电导率、pH值、温度、压力、流量等主要计量参数的准确性对肾病患者临床影响的问题,通过临床观察、检测/校准实例数据及使用现状的分析,发现血液净化装置的主要计量参数的改变,使临床症状发生变化甚至产生不良影响,提出了制定血液净化装置检测/校准技术规范的必要性和现实性。对血液净化装置主要计量参数的监控范围的设定值提出指导性建议,对校准用设备的分辨力、精度和监控值测量的示值误差等提出了要求。因而,对血液净化装置检测/校准技术规范的制定以及临床的安全使用具有实际指导意义。

The influence of the main metrology parameters’accuracy of hemofiltration equipments on clinical diagnosis of kidney disease was investigated.Analysis of clinical results suggested that the change of the parameters,including conductivity,pH,temperature,pressure and flux could lead to the change of clinical symptoms,even make the symptoms become worse.Thus,it is necessary to establish the test/calibration technique criterion of hemofiltration equipments.Based on the testing results of hemofiltration equipmen...
