Some of the machines can be set so that they will shut off if the mask is removed. Try to disable that feature to see if that helps.
I see this is your second machine in three months -- were both machines Remstar? Are you sure that Apria provided new machines to you?
A friend of mine has sleep apnea and when his stopped working after a few months he was given a new machine. I have given him the name of this site and another site I frequent but he hasn't visited either site. His new machine, in fact, was an older machine that and is a stripped down M series that doesn't provide even a slot for a data card and no way of even showing compliance.
I am wondering if you had the Pro and that was traded for the Plus? You either have one or the other as there isn't any such machine as the Pro Plus that I am aware of.
Hi Pamila, Do you have power fluctuations? Do your house lights flicker when the furnace kicks on?
You can try a ups power supply like used on computers they halt fluctuations which may be causing your machine to think it has been momentarrly unplugged. Does the plug fit snuggly in the outlet ? Check all connections . Voltage spikes can also cause machines to do things .Do you have a surge protector? Two machines in a short time makes me think power issues. Good Sleep,Chris
