A paediatric breathing system, called the Emona system has been devised because commercially available anaesthetic baby systems used in head and neck surgery did not give satisfactory results. The system provides for fresh gas inflow while the expiratory path is positioned close to the patient. A precise description and schematic presentation of its action is given. The efficiency of the Emona system was tested in 65 infants and children using blood gas analyses. Furthermore, CO2 analyses of mixed expired and inspired gases, as well as some measurements applying the respiratory nomogram, were carried out. The efficiency of the Emona system is compared with results of some other baby systems (Jackson-Rees and Ruben's systems). The problems of paediatric anaesthetic systems are discussed and the dilemma of normal values for some respiratory parameters in children exposed. The results show that the Emona system is particularly advantageous in manually controlled ventilation in comparison to the results of other authors applying mechanical respiratory support.
一种名为埃莫纳（Emona）系统的儿科呼吸系统已被设计出来，因为用于头颈外科手术的市售婴儿麻醉系统效果并不理想。该系统在呼气路径靠近患者的同时提供新鲜气体流入。文中给出了其作用的精确描述和示意图。通过血气分析对65名婴儿和儿童进行了埃莫纳系统效率测试。此外，还对混合呼出和吸入气体进行了二氧化碳分析，并运用呼吸列线图进行了一些测量。将埃莫纳系统的效率与其他一些婴儿系统（杰克逊 - 里斯（Jackson-Rees）系统和鲁本（Ruben）系统）的结果进行了比较。文中讨论了儿科麻醉系统的问题，并揭示了儿童一些呼吸参数正常值的困境。结果表明，与其他应用机械呼吸支持的作者的结果相比，埃莫纳系统在手动控制通气方面具有特别的优势。
