Abstract

Abstract: This paper first described the principles behind various monitoring functions of multi-parameter monitors in clinical use, including the measurement principles for ECG signals, respiratory rate, blood pressure, and blood oxygen saturation. The paper then detailed the testing methods, which analyzed equipment performance errors and functions through stimulated signals based on national metrological verification regulations （JJG760-2003） and quality control standards. Drawing on hospital maintenance data, it analyzed common fault types and causes, and proposed targeted solutions. Finally, specific strategies for equipment maintenance were presented, emphasizing optimized testing processes, enhanced preventive maintenance, and fault diagnosis to effectively improve the reliability of multi-parameter monitors and the efficiency of clinical operations. This research offers scientific guidance for medical equipment management.

Key words: Multi-parameter monitors, Testing methods, Fault analysis, Maintenance
