Summary

Anaesthetic breathing systems are used to deliver oxygen and anaesthetic gases to patients and remove carbon dioxide. A breathing system is most commonly attached to an anaesthetic machine, which is designed to deliver the fresh gas flow to the patient via a facemask, a supraglottic device or an endotracheal tube. The breathing system used can affect the composition of the gas and volatile anaesthetic mixture inhaled by the patient, and so it is important to understand the different breathing systems used in anaesthesia. This chapter describes the key components of the different breathing systems and explores the benefits and disadvantages of the circuits in the Mapleson classification.
