I was just about to book a static caravan for a holiday with my husband who has COPD/Emphysema when it suddenly occurred to me that you may not be able to have an oxygen concentrator in a caravan where there is a gas fire, gas stove & water heater. I know I've read in the forum of people who regularly holiday in caravans, but then they may not be on oxygen? I'd be be so grateful if someone could let me know - I'll be gutted if we can't use a caravan now he's on oxygen. But then at least I haven't actually booked it yet! . Would it make any difference if he used the portable concentrator rather than the big one that the oxygen company installs? I'm really hoping for some good news on this.
