Utilization of IQM data of GEM3000 blood gas analyzer for evaluating instrument performance / 国际检验医学杂志

ABSTRACT

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 .
