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。
This paper reports a re-breathing system for ~ (133) Xe ventilation research. This system plays a role in formulating, supplementing, and managing Xe gas in the study of lung function: measuring and controlling the ~ (133) Xe radioactivity concentration in the spirometer; measuring the CO_2 and O_2 content of air samples in the system , And can automatically fill O_2 as needed. System to achieve a balanced inhalation ~ (133) Xe.
