利用GEM3000血气分析仪IQM数据进行仪器性能评估

摘要

Objective To apply the IQM quality data of the GEM 3000 blood gas analyzer to evaluate the instrument performance and to compared it with the traditional evaluation method .Methods The precision and accuracy were calculated by using the IQM data ,the external quality control substance was adopted to verify the main performance indexes of the blood gas analyzer .Results The precision of PH ,PCO2 and PO2 calculated by using the IQM data was 0 .02% ,2 .16% and 0 .63% ,which by the traditional e-valuation method was 0 .07% ,1 .68% and 1 .28% respectively ,the accuracy of PH ,PCO2 and PO2 calculated by using the IQM data was 0 .00% ,1 .15% and 0 .49% ,which by the traditional evaluation method was 0 .11% ,2 .91% and 1 .07% respectively .Conclu-sion The intelligent quality management can provide objective and reliable indicators for the performance evaluation of the blood gas analyzer ,and compared with the traditional performance evaluation scheme which is more simple and convenient to operate .%目的：使用GEM Premier3000血气分析仪上IQM质控数据评估仪器性能，并与传统评估方法进行比较。方法利用IQM 数据计算精密度和正确度，采用外部质控物验证血气分析仪主要性能指标精密度和正确度。结果利用IQM 数据计算血气分析仪pH、PCO2、PO2精密度分别为0．02％、2．16％、0．63％，而传统评估方法为0．07％、1．68％、1．28％，利用IQM 数据计算血气分析仪pH、PCO2、PO2正确度分别为0．00％、1．15％、0．49％，而传统评估方法为0．11％、2．91％、1．07％。结论通过智能化质量管理能为实验室客观的评价血气分析仪的性能提供客观、可信的指标，与传统的性能评估方案相比更为简便、易行。
