Abstract

The use of expensive anaesthetic agents and the need to reduce operating-theatre pollution has promoted the use of circuits which minimize gas usage. A closed circuit has been developed in the University of Manchester (Beatty et al. 1982). The circuit maintains a constant volume at end expiration. This is achieved by the opposing action of a spring mechanism attached to a bellows of low mass.
