Reliability of patient care equipment could be enhanced if failures could be predicted and repairs made on a routine instead of emergency basis. The paper describes the efforts of the Biomedical Engineering Department at Brookdale Hospital Medical Center to use changes in accuracy of selected parameters as failure predictor. Monthly precision tests of ECG rate computers, strip chart recorders and waveform analysis of defibrillator discharges were used in this experiment. For defibrillators and strip chart records failures could clearly be predicted but the results for ECG rate computers are still inconclusive.
如果能够预测故障并进行常规而非紧急维修，患者护理设备的可靠性就可以得到提高。本文描述了布鲁克代尔医院医疗中心生物医学工程部门利用选定参数准确性的变化作为故障预测指标所做的努力。本实验采用了心电图心率计算机的月度精度测试、带状图表记录仪以及除颤器放电的波形分析。对于除颤器和带状图表记录，故障能够明确预测，但心电图心率计算机的结果仍无定论。
