ok i'll accept your reasoning to move it away from entonox however i still strongly feel that nitrous oxide oxygen is an unwieldy and poor title choice what else could we use what about for example gas and air the popular colloquial term not that i'm saying that that is the best choice just looking for a good alternative your suggested title would be kinda like moving plaster a registered trademark to 'non fluffy adhesive sterile dressing' a term which i have seen used in a few training materials and which amuses me to this day p the plaster article actually exists at adhesive bandage a good term let's see if we can find the 'adhesive bandage' for entonox suggestions talk
