摘　　要：肺弥散功能是指气体交换的速率,主要反映了肺泡毛细血管膜的通透性,是评估肺部微血管病变的重要指标。在肺弥散功能检查中,测试气体的选择是基于多种因素考虑的。由于直接计算氧气(O_(2))和二氧化碳(CO_(2))的弥散量方法复杂,且存在多种影响因素,因此临床上更倾向于将一氧化碳(CO)作为测定肺弥散功能的理想测试气体,指示气体通常为氧气、氦气、甲烷、乙炔等。如何选择合适的气瓶确保混合气体能够稳定储存在气瓶中是肺弥散功能测定结果是否准确的重要影响因素。从气瓶材质的选择、气瓶的处理方法方面进行了研究,并对不同类型气瓶价格进行比对,最终筛选出了满足肺弥散功能测试用混合气体气瓶,满足各类使用者的需求。Pulmonary diffusion function refers to the rate of gas exchange,mainly reflecting the permeability of the alveolar capillary membrane,and is an important indicator for assessing pulmonary microvascular disease.In the examination of pulmonary diffusion function,the choice of test gas is based on various factors.Due to the complexity of directly calculating the diffusion amounts of oxygen(O_(2))and carbon dioxide(CO_(2)),and the presence of multiple influencing factors,clinically,carbon monoxide(CO)is preferred as the ideal test gas for determining pulmonary diffusion function,with indicator gases typically being oxygen,helium,methane,acetylene,etc.How to select the appropriate gas cylinder to ensure that the mixed gas can be stably stored in the cylinder is an important factor affecting the accuracy of the results of pulmonary diffusion function determination.The selection of gas cylinder materials and the treatment methods of gas cylinders were studied,and the prices of different types of gas cylinders were compared.Moreover,the gas cylinders meeting the requirements of pulmonary diffusion function test were selected,which met the needs of various users.
