3.1. Intended Use
The Dialflow Regulator is intended to deliver medical oxygen at one of eleven pre-set
rates directly from a high pressure oxygen cylinder. Flow is indicated in litres per minute
(l/min) and is visible through a window adjacent to the flow selection dial.
Medical oxygen is or should be considered a drug and should only be used for medical
purposes on the authority of a physician and then strictly in accordance with their
instructions. Always refer to the medical oxygen product labelling.
3.2. Technical Description
The Dialflow Regulator reduces the high pressure of the oxygen cylinder to a safe, more
manageable pressure for application to patients. There are many types of oxygen
cylinder connection used and these may be different from one country to another, ensure
that this regulator is the correct connector for the cylinder to be used.
Once connected to an oxygen cylinder, and with the cylinder valve opened, the user may
select the flow rate prescribed by rotating the gas flow selection dial until the correct flow
rate is seen in the viewing window.
The rate at which gas flows from the regulator is controlled by a hole of known size and
accuracy. Each flow rate has a different size hole. The output connector allows the user
to connect an oxygen facemask, cannula or other application device as appropriate.
4. Operating Instructions
4.1. Preparation and Connection

presence and condition of the input connector seal, which for pin index regulators is a
washer type seal (Bodoc) and for bullnose regulators and O-ring.
Fit the regulator to the cylinder ensuring that it is properly mated and the connectors are
done up hand tight.
