Operating theatres have a distinct sound. Unless dominated by the roar of an orthopaedic chain saw, it is the anaesthetist and his or her monitors that provide that familiar backdrop to the theatre. Bleeping, clunking, suction, and alarm bells reflect the degree of sophistication achieved in modern anaesthetic monitoring--at least in the affluent Western world.
In the United Kingdom, we worry about how we are going to replace thousands of anaesthetic machines without hypoxic guards, but anaesthetists in isolated or less developed parts of the world are grateful for a machine that works at all.
Most modern anaesthetic machines are complicated expensive pieces of equipment costing between £20 000 (a31 066; $31 882) and £40 000.
