Oxygen Regulators (also called pressure reducers) are designed to reduce the high pressure of an oxygen cylinder to a low pressure. This can be used safely for delivering a flow of oxygen to a patient either directly via an oxygen therapy face mask, bag-valve-mask, closed circuit/re-breather system, or in conjunction with a secondary pressure reduction system such as, demand valve, BVM refill valve or a ventilator etc.
There are two types of regulators:
There are generally two "families" of pressure reduction regulators, diaphragm or piston types. Whilst diaphragm regulators are very accurate, they tend to be big and heavy and require more care, on the other hand, piston regulators are smaller and more durable, but intrinsically they are less accurate – that was before the Allied Laser Spectrum Regulator.
There is now only one type of medical oxygen cylinder valve used in Australia, it is called a Pin Indexed, which matches an ISO standard. The old screw on type, or bull nose has been phased out over the years (2010 – 2011).
