自从发现了松弛剂药物以来，许多需要控制通气的技术被引入。最常用的方法是麻醉师有节奏地挤压袋子。本文介绍了一种自动“袋挤压机”，它满足以下要求的发展。(1)通气设计应尽量减少间歇性正压对麻醉患者心血管的影响。(2)这台机器应该为麻醉师提供尽可能多的关于病人的通气和放松程度的信息。这将在很大程度上补偿与袋子接触的损失。(3)机器本身应该足够小，可以放置在麻醉仪器上。(4)它应该在没有辅助能源的情况下利用所供应的气体进行操作。
Since the discovery of the relaxant drugs, many techniques requiring controlled ventilation have been introduced. The method most commonly used is the rhythmical squeezing of a bag by the anzesthetist. This paper describes the development of an automatic ‘bag squeezer’which fulfils the following requirements.(1) The ventilation should be designed to minimise the cardiovascular effects of intermittent positive pressure on the anzsthetised patient.(2) The machine shouid provide the anzsthetist with as muchinformation as possible about the ventilation and the degree of relaxation of the patient. This will then largely compensate for the loss of contact with the bag.(3) The machine itself should be sufficiently small to stand on an anzsthetic apparatus.(4) It should operate from the gases supplied without ancillary sources of energy.
