Pressure Regulators

Pressure regulators are used on anaesthetic machines for three purposes:

• to reduce the high pressure of gas in a cylinder to a safe working level

• to prevent damage to equipment on the anaesthetic machine, e.g. flow control valves

• as the contents of the cylinder are used, the pressure within the cylinder decreases and the regulating mechanism maintains a constant outlet pressure, obviating the necessity to make continuous adjustments to the flowmeter controls.

The principles underlying the operation of flowmeters are described in detail in Chapter 30.
