摘　　要：氧气是突发公共卫生事件中救治重症患者的重要保证,其能否正常保障和供应成为医院都需要面对和解决的首要问题。本研究通过了解突发公共卫生事件期间医院收治重症患者以及氧气保障供应情况,探讨医院在此期间出现氧气供应紧张问题的根本原因,从临床医疗救治的实际需求出发,发现造成供氧不足的主要原因是医院液氧储备能力受限、汽化效率降低、输送管径偏细、二级减压箱节流等。建议对医用液氧储罐容积为5 m^(3)的限制要求进行修订,医院可根据实际医疗需求进行调整和配置,优化汽化器和管道系统的设计与选型,医用气体系统质量控制与检测应常态化和规范化,在法规允许及临床医师认可的情况下使用富氧空气(93%氧)为普通病区供氧,将更多的医用氧(≥99.5%)供应给需要生命支持的重症患者使用。Oxygen is an important guarantee for the treatment of critically ill patients in public health emergencies,and its normal guarantee and supply have become the primary issue that every hospital needs to face and solve.The fundamental reasons for the shortage of oxygen supply in hospitals during the period of public health emergencies were explored by understanding the admission of critically ill patients and the supply of oxygen.Based on the actual needs of clinical medical treatment,it was found that the main reasons for insufficient oxygen supply were limited liquid oxygen storage capacity,reduced vaporization efficiency,small diameter of delivery pipe,throttling of secondary pressure reducing boxes,etc.It was recommended the limit requirement for the volume of medical liquid oxygen storage tanks be revised to 5m^(3).Hospitals can adjust and allocate according to actual medical needs,optimize the design and selection of vaporizers and pipeline systems,normalize and standardize the quality control and testing of medical gas systems,and when allowed by regulations and approved by clinical physicians,use oxygen-enriched air(93%oxygen)to supply oxygen to general wards,and provide more medical oxygen(≥99.5%)to critically ill patients who require life support.
