A logical development of the closed circuit is described, from a basic resuscitation device, through various modifications, to a circle system incorporating an oxygen demand valve, adsorbers for both carbon dioxide and halothane, and some specific safety features. The behaviour of the circuits has been investigated in relation to elimination of nitrogen, concentrations of halothane and circuit leaks.
本文描述了闭路系统的逻辑发展过程，从基本的复苏设备开始，经过各种改进，发展到一个包含氧气需求阀、二氧化碳和氟烷吸附器以及一些特定安全特性的循环系统。研究了该系统在氮气清除、氟烷浓度和系统泄漏方面的性能表现。
