Can firebreaks be fitted to a dual lumen cannula fitted to a oxygen conserver?
Yes they can but firebreaks only need to be installed in the oxygen delivery lumen and not in the sensing lumen.

It is important to use the preferred connectors when assembling the Firesafe™ Cannula Valve into an oxygen delivery circuit. The international standard (ISO 13544-2 – Respiratory Therapy Tubing and Connectors) prescribes exact dimensions for the barb connector on ‘male’ oxygen therapy connectors. The corresponding ‘female’ flexible connectors (or ‘trumpet connectors’) have been designed by patient … Read more
We recommend two firebreaks are installed. The first should be close to the patient e.g. at the interface to a nasal cannula with a very short or no extension tubing. The second should be placed close to the source of supply. • Instructions for use
The Firesafe™ Cannula Valve and Firesafe™ Nozzle have been carefully designed to minimise resistance to the flow of oxygen. Considering the worst case – an oxygen concentrator with a non-backpressure compensated flowmeter calibrated at atmospheric pressure. If two Firesafe™ valves were installed in series, at an oxygen flow of 5 l/min, the actual oxygen flow … Read more
Where an oxygen concentrator is being used, it is recommended to install a Firesafe™ Nozzle at the interface between with the concentrator oxygen outlet and the oxygen tubing to isolate the oxygen supply at source in the event of a fire. A Firesafe™ Cannula Valve should then be installed close to patient, normally at a position … Read more
Yes, the Firesafe Cannula Valve can be fitted to the small bore oxygen tubing inlet, whether that is fed into the CPAP ventilator or into a port in the patient breathing circuit. The temperatures of the gas delivered are very low in comparison to the activation temperature of the valve, so there is no risk of it … Read more
The Firesafe™ Cannula Valve/Firesafe™ Nozzle comprises a spring loaded valve probe contained within a moulded housing. In normal condition the valve is held open by means of a T‐bar arrangement on the valve probe at the downstream end that sits on a fusible ledge. The valve is actuated when the fusible ledge softens as a … Read more
