M Series DS100 CPAP Machine

[DLMdoc]

Does anyone have the M Series DS100 CPAP Machine?

I just got it to replace an old machine and it's driving me insane!! The machine makes different noises when I'm inhaling and exhaling. The change in noise is keeping me awake!

Is this the design of this machine or is something wrong with mine?

Thanks!

Prob have Cflex on and that is what changes the motor pitch when you breath. Either turn it off or down a notch.
Course knowing what I know now - I would return that machine for one that provides data.

NO nothing on DS 100 - no cflex no card - NOTHING

Quite a few of the M series machines seem to be whiney or noisy. If you got it from a brick and mortar DME in your town, perhaps you can talk them into exchanging it for another. But I'd be sure I listened to the machine at your pressure, using your mask, there at the DME until you heard a quiet one. Even a quiet one can become noisy later. And vice versa.

It's always amazed me that machines which are supposed to be used during sleep are not ALL designed to be dead-quiet. A couple of the ResMed S8 "II" series machines with "Easy Breathe" are the quietest ones I've tried lately.

I have two M-Series APAP w/AFlex machines (primary and backup). Both were acquired the same week and both are "whiney". The whine occurs when I change from inhale to exhale and vice versa. Other forum members have commented on this inhale/exhale whiney noise. Some nights I notice it more than others, plus I notice it during some hours of the night more than others. There are even nights when I don't notice it at all. I run a table fan adjacent to the bed at either low or medium speeds and its "white noise" helps to cover up the whine. I think that the type of mask one is using may affect the frequency and amplitude of the whine but have not investigated this theory (it is on my ToDo list for later). BTW, my machines are not "noisy", just "whiney".

Because of the whine, my next machine will most likely not be a Respironics.
