O-Series regulator with attached pressure gauge. If you have a particular interest in this regulator, it is described in detail in Russell. You are probably more familiar with the small transport oxygen cylinders with the integrated pressure regulator, flowmeter and pressure gauge.
T/F Pressure regulators should be regularly lubricated with a hydrocarbon based grease to prevent sticking.
T/F Pressure regulators for oxygen may be used with air but not nitrous oxide
T/F Adiabatic gas expansion can cause moisture to freeze and jam pressure regulators
T/F Rupture of a regulator diaphragm can cause loss of gas from the anaesthetic circuit to the pipeline.
T/F Pressure regulators convert a constant upstream pressure to a variable downstream pressure
