Abstract

A general solution is presented to the problem of finding the minimum fresh gas flow requirements, during spontaneous ventilation, of anaesthetic breathing systems in the Mapleson classification. The solution is applicable to any pattern of breathing, dead space volume and tidal volume. The method is graphical and its use and understanding require no mathematical skills. However, if an analytical form of the respiratory waveform is known, the method is easily extended by use of calculus to obtain a precise analytical solution.

摘要

针对在Mapleson分类的麻醉呼吸系统中，求出自发通气期间最小新鲜气体流量需求这一问题，给出了一个通用解决方案。该解决方案适用于任何呼吸模式、死腔容积和潮气量。该方法是图解法，其使用和理解不需要数学技能。然而，如果已知呼吸波形的解析形式，通过使用微积分，该方法很容易扩展以获得精确的解析解。
