Abstract

Mapleson's A and D are the most efficient semiclosed nonabsorbing circuits used for spontaneous and controlled ventilation. A new device, the MultiCircuit System, allows single-lever selection of Mapleson A or D functions, when used with the conventional two hoses or Mera F coaxial circuit attached. In the A mode, in a study performed on awake volunteers, the MultiCircuit System with two hoses performed comparably to the Magill attachment. When coupled with the Mera F circuit as a coaxial system, the MultiCircuit System was less efficient than the Magill, and had a resistance to expiration exceeding 2cm H2O pressure at a gas flow of 30 l/minute.

摘要

Mapleson A和D是用于自主通气和控制通气的最有效的半紧闭无吸收回路。一种新装置——多回路系统，当与传统的双管或Mera F同轴回路连接使用时，可通过单杆选择Mapleson A或D功能。在A模式下，一项针对清醒志愿者的研究表明，配备双管的多回路系统的性能与Magill接头相当。当作为同轴系统与Mera F回路连接时，多回路系统的效率低于Magill接头，并且在气体流量为30升/分钟时，呼气阻力超过2厘米水柱压力。
