The control of depth of anaesthesia has been viewed as a control-system problem the solution of which can involve both feedback and feedforward techniques. The nature of the problem in Clover's day and the solutions he found have been examined. A similar analysis has been made in respect of the modern anaesthetist. Finally, the way in which computers may aid the anaesthetist in his task has been illustrated by reference to various attempts reported from around the world and, in particular, by describing the development in Cardiff of a system which should produce, in the brain of the patient, any tension of an inhaled anaesthetic which the anaesthetist chooses to specify.
麻醉深度的控制一直被视为一个控制系统问题，其解决方案可能涉及反馈和前馈技术。已经研究了克洛弗时代该问题的性质以及他找到的解决方案。对现代麻醉师也进行了类似的分析。最后，通过参考世界各地报道的各种尝试，特别是描述了在加的夫开发的一个系统，来说明计算机如何协助麻醉师完成其任务。该系统应在患者大脑中产生麻醉师选择指定的任何吸入麻醉剂浓度。
