Sleep Apnea Support Group
Sleep apnea is a common sleep disorder characterized by brief interruptions of breathing during sleep. People with sleep apnea partially awaken as they struggle to breathe, but in the morning they may not be aware of sleep disturbances.

Worth a shot anyway - or call doctor in NJ who ordered machine and have them give a script for a new one to a DME company where you are now, provided she's been doing fine with the machine on current settings?
Explain her age, recent surgery, etc, maybe they'll cut you some slack!!
Good luck!!
Let us know how you make out.

Trying to sleep that is. Don't they understand how important it is to have a working CPAP machine?
try this, turn it on and drop on floor from height of about 8 inches, the shock may start it running, worked for me
