I just got a respironics auto w/cflex dropped off by rt (temporary till titrated)....do you know if this is sposed to happen? The machine was turned off (i think) and I tried on the interface prongs to "practice"...when I started breathing, the machine started to blow air! Will a remstar auto do that automatically if it senses you breathing, even if its turned off? I tried several times and it happened each time. Also there's always numbers on it when that happens. Normal? Terry
