A Nova 1 potassium analyser has been evaluated for the first 3 months of its use in a cardiac surgical intensive care unit. The machine was out of action for 11 out of 104 days. 515 external calibrations were performed with 4.50 mmol/l potassium standards: mean 4.49 mmol/l, standard deviation 0.07. 692 comparisons were made with routine laboratory flame photometer measurements on the same sample: correlation coefficient r = 0.815. It is concluded that Nova 1, if kept in working order, can provide potassium estimations quickly and accurately.
一台Nova 1钾分析仪在心脏外科重症监护病房使用的前3个月进行了评估。在104天中有11天该机器无法正常工作。使用4.50 mmol/l钾标准液进行了515次外部校准：均值为4.49 mmol/l，标准差为0.07。对同一血样与常规实验室火焰光度计测量值进行了692次比较：相关系数r = 0.815。结论是，如果保持正常运行，Nova 1能够快速且准确地提供钾含量测定结果。
