摘要
本文报道了一种用于^(133)Xe通气研究的再呼吸系统。这种系统在肺功能研究中起着配制、补充和管理^(133)Xe气体的作用:对肺活量计中^(133)Xe放射性浓度进行测量和控制;能测量系统中空气样本CO_2和O_2含量,并能根据需要自动补O_2。系统实现了平衡吸入^(133)Xe。
A 133Xe rebreathing system is described for performing lung ventilation. The system is designed mainly for supply and disposition of 133Xe gas to be used for pulmonary function studies. The measurement and control of radioactivity concentration of 133Xe gas made in spirometer. The air sample of the system can be also analyzed for concentration of CO2 and O2.
