I just wanted to know if someone can give me an idea about NITRONOX (same as ENTONOX in the UK). We are looking for a replacement and we have been quoted with MATRX Digital MDM unit which is a continuous flow device. Unlike NITRONOX which is a demand valve flow system. I have tried giving them with ENTONOX but they prefer to get a latest new device that could deliver 50/50 premix of Gas (N2O/O2). Entonox has an issues with cylinders here in Canada, where they have a backlog or delay of cylinder gas.
Do someone knows a compatible replacement that uses a demand valve system?
Thanks for any suggestion.
