Abstract

Abstract: 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. Highlights: Propose a medical oxygen gas source calculation flow model for the treatment of new coronary pneumonia. Introduce the proportion of critically ill patients converted to respiratory distress patients, which is used to correct the difference in the amount of oxygen used by different patients in the ward for respiratory support. Obtain the average flow rate of oxygen consumed by various oxygen therapy terminals, which is used to calculate the design and selection of oxygen supply system. The recommended average flow rate of high-flow oxygen delivery is 15–25L/min; the coefficient of simultaneous use of oxygen at the end of the ward is recommended to be 0.7–0.9.
