Abstract：Objective To allocate human and material resources according to the fault level of the negative pressure system of the
medical center, to design emergency plans and to improve the disposal efficiency of all levels of departments after fault emergencies.
Methods Failure mode, effects and criticality analysis (FMECA) method was used to comprehensively analyze the possible
fault types and harm degree of the negative pressure system of medical center. Combining with other influencing factors, fuzzy
evaluation and analytic hierarchy process (AHP) were used to classify the fault levels. According to the fault level and fault type,
the corresponding emergency measures and disposal process were designed, and a set of executable emergency plan were formed,
implemented and its effect was verified. Results After the implementation of the plan, the severity level of 8 kinds of faults in the 24
kinds of fault types in the negative pressure system of the medical center were significantly reduced. The influence range score of 20
fault types decreased from more than 6 points to less than 5 points. The maintenance cycle of 18 fault types was obviously shortened.
The comprehensive quantization score Q of the fault level of the reaction system decreased significantly in 22 items.
Conclusion Using FMECA-AHP method to classify the system faults and design the corresponding emergency plan can effectively
improve the emergency treatment efficiency when the negative pressure system of medical center breaks down.
