ABSTRACT
Medical gases can be identified simply if they are supplied at different pipeline pressures. Routine maintenance errors, accidental pipeline cross-connections, or gas failures, can be automatically detected by incorporating a pneumatic unit with pressure-sensitive valves into the anaesthetic machine. A fail-safe method of ensuring the delivery of the correct gases to the patient is described.
