Objective： To provide reasonable engineering countermeasure for the failure reason of pressure fluctuation curve appeared in treatment process of medical hyperbaric oxygen（produced by Shandong Moon Group） in order to improve the clinical safety performance of medical hyperbaric oxygen. Methods： To analyze the failure reason for fluctuation of hyperbaric oxygen pressure cure in 3 stages（pressuring stage, stabilization stage and decompression stage） based on working principle of medical hyperbaric oxygen; and provide engineering countermeasure for reducing the failure rate of medical hyperbaric oxygen. Results： Through analyzing the failure of medical hyperbaric oxygen, environmental factors and mechanical properties were confirmed as the main factors causing the failure of the equipment; through improve the adaptive capacity to environment, design of structure and performance of mechanical parts, the medical hyperbaric oxygen could be normal operated. Conclusion： The failure rate of hyperbaric chamber can be reduced and the treatment effect for patient can be improved when we improve the research capability of medical hyperbaric oxygen equipment, increase the adaptive capacity to environment for equipment and pay more attention to the professional quality training for maintenance technician.
