A laboratory investigation of a multigas monitor for anaesthesia (EMMA)

Abstract

A new volatile anaesthetic gas analyser (EMMA) was tested in the laboratory. It was shown to have an accurate, linear response, with minimal zero drift and to be almost unaffected by carrier gases. It is a versatile and sensitive machine with a fast response time indicating that it might be used for breath-by-breath monitoring. The EMMA is a useful new anaesthetic gas analyser than should find widespread clinical usage.
