RESUMEN
Objective: To reduce the risk of ventilator in clinical use by using technical management so as to enhance cure rate for patients. Methods: Through a series of methods included of clinical investigation, statistic analysis of data, socio-technical system model and others to analyze and assess risk factors which were possibly produced in the cure process of ventilator. And the relevant risk regulation indicators were formulated as above information. Results: The formulation about risk control criterion of operation in the cure process of ventilator provided various aspects, which included of the material qualities of ventilator and breathe pipeline, clinical service environment, human factor and others, for clinical engineer to control risk so as to ensure the life safe of patients. Conclusion: The clinical engineering department should adopt technique management way to analyze the cure process of ventilator, and control risk from aspect of clinical engineering. Therefore, it can efficiently reduce the risk of ventilator in clinical application and promote the safety and efficiency of ventilator in the treatment.
