Abstract：Objective To explore the effect of risk analysis tools and Internet of Things technology on risk alarm management of
hospital emergency medical equipment. Methods The failure modes and effects analysis (FMEA) model was used to analyze and
classify the risk alarms of hospital emergency medical equipment, calculate the risk priority number (RPN), evaluate the severity and
formulate improvement measures. At the same time, the Internet of Things technology was used to collect the risk alarms in real time.
The effect of emergency medical equipment risk management, the condition of emergency medical equipment repair and the accuracy
of emergency medical equipment alarm treatment were compared before and after implementation. Results The risk alarms of
emergency medical equipment were classified into three categories: equipment failure alarm, equipment health alarm and equipment
health alarm to fault alarm. After the implementation of the FMEA mode and the Internet of Things technology management, the
RPN values of the corresponding failure modes of the three types of risk alarms of emergency medical equipment were reduced,
and the difference before and after the implementation was statistically significant (P<0.01). The failure reporting rate of emergency
medical equipment was significantly lower than that before implementation, the difference was statistically significant (χ2=15.605,
P＜0.001). Medical staff were better than before in classification of emergency medical equipment alarm and correct rate of alarm
information processing and the difference was statistically significant (χ2=9.205, P=0.002; χ2=7.445, P=0.005). Conclusion Risk
analysis tools combined with Internet of Things technology can effectively evaluate and control of the medical equipment risk alarms
and provide more adequate guarantee for clinical safety.
