Abstract
Breathing systems are designed to deliver oxygen, air and anaesthetic agent to the patient, and, in the case of circle systems, allow the recycling of expired gases after removal of CO2. A relatively small number of distinct breathing varieties are used in modern practice. They consist of similar components but in different configurations, with the layout of each determining their clinical attributes and preferred role. Various classification systems will be described in this article. Modern anaesthesia machines primarily use circle systems with CO2 absorbers designed for low-flow anaesthesia.
期刊介绍：
Anaesthesia and Intensive Care Medicine, an invaluable source of up-to-date information, with the curriculum of both the Primary and Final FRCA examinations covered over a three-year cycle. Published monthly this ever-updating text book will be an invaluable source for both trainee and experienced anaesthetists. The enthusiastic editorial board, under the guidance of two eminent and experienced series editors, ensures Anaesthesia and Intensive Care Medicine covers all the key topics in a comprehensive and authoritative manner. Articles now include learning objectives and eash issue features MCQs, facilitating self-directed learning and enabling readers at all levels to test their knowledge. Each issue is divided between basic scientific and clinical sections. The basic science articles include anatomy, physiology, pharmacology, physics and clinical measurement, while the clinical sections cover anaesthetic agents and techniques, assessment and perioperative management. Further sections cover audit, trials, statistics, ethical and legal medicine, and the management of acute and chronic pain.
