Air Mini Pulsing

[mhauby@gmail.com]

I have a Resmed Air Mini. In the middle of the night, the machine (not mask) starts pulsing in and out, waking me up. If I turn the machine off and back on, it starts again. I have consulted with Resmed who, besides having a very low level of support through my dealer, was basically unhelpful. Thought it could be central sleep apnea(not obstructive). They took my machine back and replaced it, and the same thing is happening with the new one. I dont know what to do...so far a waste of $1000
