The anaesthetic machine: trace the gas-flow path and its safety devices
The canonical machine SAQ — the pipeline and cylinder supply, the Pin Index system, the oxygen failure alarm, the Thorpe-tube flowmeters, the gas proportioning device and its limits, the vaporiser, the oxygen flush, the oxygen analyser and the AAGBI 2012 pre-use check.

Prompt
Trace the path of a gas molecule from the hospital supply to the patient, naming each component of the anaesthetic machine in order. At each stage, state the working pressure (or flow) and the safety device that protects the patient. End with the pre-use check.
