just a bit confused - someone said to get one with usable software....do these come with software that you can adjust the flow with? My wife has one and it is hard coded by the supplier of the cpap. Is it possible to get one that you can adjust yourself

Am now a member if anyone wants to email me off list ...........looking for free or exceptionally great deals. Supporting wife, her two kids, and 2 grandkids --- doesn't leave much ...........thanks to everyone for their replies
