Respiratory supporting, as an important medical treatment for new coronavirus pneumonia patients, must be effectively guaranteed by medical oxygen supply. However, the medical oxygen system designed and configured by the existing hospitals according to the current specifications cannot meet the oxygen needs for patients with new coronavirus pneumonia. This paper aimed to study the design of medical oxygen system in new coronavirus pneumonia emergency hospital. By investigating the oxygen treatment plan for the novel coronavirus pneumonia patients in the health emergency hospital, the oxygen treatment characteristics of different patients were studied. The oxygen characteristics of different respiratory support terminals were explored to study the oxygen demands of new coronavirus pneumonia emergency hospitals. Through calculating flow rates of medical gas system air source referring to ‘technical code for medical gases engineering’, the proportion coefficient of severe patients converted into respiratory distress patients was introduced, and the model of calculating flow rates of medical oxygen system air source in emergency hospital was proposed. The cases were verified in a typical health emergency hospital that the developed calculation flow model of medical oxygen source met the demands of hospital oxygen. The outcomes provide a reference for the design and construction of medical oxygen in such health emergency hospitals.

呼吸支持作为新型冠状病毒肺炎患者的重要医疗救治，必须通过医用供氧得到有效保障。但是，现有医院按照现行规范设计和配置的医用氧气系统无法满足新型冠状病毒肺炎患者的氧气需求。本文旨在研究新型冠状病毒肺炎急诊医院医用氧气系统的设计。通过调查卫生急诊医院新型冠状病毒肺炎患者的氧疗方案，研究不同患者的氧疗特点。探索不同呼吸支持终端的氧气特性，研究新型冠状病毒肺炎急诊医院的氧气需求。通过参照《医用气体工程技术规范》计算医用气体系统气源流量，引入重症患者转化为呼吸窘迫患者的比例系数，建立了急救时医用氧气系统气源流量计算模型医院提出。通过某典型卫生急救医院案例验证，所开发的医用氧源计算流程模型满足医院供氧需求。研究结果可为此类卫生应急医院医用氧气的设计和建设提供参考。提出了急诊医院医用氧气系统气源流量计算模型。通过某典型卫生急救医院案例验证，所开发的医用氧源计算流程模型满足医院供氧需求。研究结果可为此类卫生应急医院医用氧气的设计和建设提供参考。提出了急诊医院医用氧气系统气源流量计算模型。通过某典型卫生急救医院案例验证，所开发的医用氧源计算流程模型满足医院供氧需求。研究结果可为此类卫生应急医院医用氧气的设计和建设提供参考。
