Defective RESMED Aircurve A10 auto bipap

[PaulC]

I received the Resmed Aircurve A10 auto bipap machine 2020-11-07.
Over the course of the next year, it occasionally emits a clicking noise that occurs just before inhale peak, and then also at start of exhale, like an audible valve closure. (attachment "RESMED-A10-CLICKING-NOISE.zip" is a compressed mp3 file)
A bit annoying, but too infrequent to pursue a remedy.

Then after I had it about 22months, it started constantly emitting a whining noise with every breath, like a turbine/grinding sound. (attachment "RESMED-A10-WHINING-NOISE.zip" is a compressed mp3 file)
Annoying enough that my wife exiled me to the guest bedroom.
I assembled a sound-dampening enclosure and placed the bipap machine inside it.
I had concern that the sound dampening material might outgas some undesirable compounds, so I also hooked up an old CPAP machine for the sole purpose of blowing low pressure clean filtered air into the enclosure, directed at the bipap air inlet.
At least that approach got me out of exile.

I called Resmed to see what they could do, I assumed the device has a 2 year warranty.
They said I had to go through the equipment provider, as Resmed cannot interact directly with patients.
I called the provider, they said the device really only had a 1 year warranty, and they declined to contact Resmed for help, as in their experience Resmed will not do anything.
The best the provider could do is sell me a new device, at my expense, which I declined.

So I'm stuck with this "mechanically challenged" Resmed bipap device for another 3 years under Medicare rules.
I just hope it's delivering the prescribed pressure profiling in its noisy and questionable condition.

From what I can gather from online searches, the problem is likely a "failing pneumatic block".
I'd be happy to fix it myself if I could just acquire the replacement part.
Does anyone know of any sources for Resmed replacement repair parts for this device, specifically the pneumatic block assembly?

p.s.
I had to compress the mp3 files into zip files, because mp3 is not a natively allowed file type for attachments in this forum

You can't always believe the DME...THEY LIE !
Here is the Resmed Warranty....it's 2 years on a CPAP.

Yes, that's pretty much my dilemma: I know it's supposed to be a 2 year warranty, but Resmed won't talk with a patient, and the DME is basically doing the "sorry, but we can't/won't do anything".
Without someone from Resmed actually reading this thread and offering to help, my initial question seems to be my only option:

Does anyone know of any sources for Resmed replacement repair parts for this device, specifically the pneumatic block assembly?

Over the course of the next year, it occasionally emits a clicking noise that occurs just before inhale peak, and then also at start of exhale, like an audible valve closure.

The clicking noise on ResMed's is often the clam-shell tank opening and closing when breathing in and out. To determine if this is the cause, squeeze the tank while breathing and see if it stops.

Causes:

• Tank not seated properly
• Lid/gasket not seated properly
• Warn tank

You had a two year Warranty, but now it's past two years. If you originally called prior to the two year warranty expiration call them up and start screaming bloody murder.

I assembled a sound-dampening enclosure and placed the bipap machine inside it.
I had concern that the sound dampening material might outgas some undesirable compounds, so I also hooked up an old CPAP machine for the sole purpose of blowing low pressure clean filtered air into the enclosure, directed at the bipap air inlet.

Off-gasing is unlikely, but ensure the ResMed's air inlet is by the opening of the enclosure, with the enclosure opening larger than the the enclosure opening.

From what I can gather from online searches

You might have better search results, and get ResMed Air10 specific part names if you used the correct names to describe your device.

ResMed's are *not* Bipaps. Bipaps are trademarked names for Respironics machines.

not sure they'd sell you the part as they do repairs. but it may be a source-

highly regarded in the commuity.

btw, what you have is a bilevel not bipap.

good luck!

My Aircurve 10 VAuto (Not a "bipap™") started making strange noises, and started behaving strangely because the thin hypoallergenic filter was partially collapsed into the intake and presenting very high airflow resistance. There's nothing to support the filter at the bottom of the opening.

Turn the machine on and open the filter door to check.

If it still makes noise and you really want to replace the blower (the pneumatic block is the blower and surrounding assembly, it's easy enough to open up the pneumatic block and get the blower out) then go here:

Thanks, I tried the tank reseat several times early on, it's not the source of the clicking. Take a listen to the attachment "RESMED-A10-CLICKING-NOISE", it sounds like a noisy valve actuation to me.

Yes, I'll probably call Resmed and raise the noise level.

The device is a bi-level Aircurve 10 VAuto, 370-4123/1

I've attached a photo of the sound dampening enclosure, the outgassing from the rubberized panels was my concern, so I rigged up an old Philips CPAP machine, set it to a constant 4cm(lowest it goes), and then pipe it's filtered output to an old mask that sits loosely against the A10 air inlet. (just enought to get a slightly higher pressure clean airflow source than ambient)

Thanks, I previously checked the filter, it's good, see photo. It makes the same whining noise even with the filter door open.
Please listen to the attachment "RESMED-A10-WHINING-NOISE" and let me know what you think that could be from.

And Thanks Very Much for the Alibaba link to the blower assembly!!

The Respironics blowing in filtered air is completely unnecessary, overcomplicates it, creates another point of failure, it being limited to 4CM could inhibit the airflow and result in less pressure on your VAuto. As mentioned earlier a hole a little bit bigger than the VAuto's inlet will suffice. There really is no need to filter the air entering your dampener.

We are all well aware what it is. The bipap correction, is because using "bipap" in your search will result in poor returned results because it is incorrect.

There are no valves in the machine. none. And nothing in the machine that would 'click', just a fan and open passages between the inlet and outlet.

So, you used a recalled because of cancer causing VOCs and shredding foam machine to feed the AC10? *blink blink* Ok, sure.

At least you're using (multiple?) anti bacterial filters, which will reduce the amount of air considerably.

An enclosure hole for the air inlet wouldn't work, because the air inlet is where the noise is most loudly emanating from.
The mask fed by the Respironics is a very loose fit, only to flood the area with clean air. WHen the A10 demands higher flow, it can easily pull it from the surrounding area. But maybe I will try increasing the Respironics pressure a bit, thanks.
I'm not worried about the cpap adding a point of failure, I have several more old cpap's lying around to replace it

It sounds like mine did when the intake was partially blocked, maybe something got sucked inside at some point.

Thanks, I guess I'll look online for disassembly guidance so I can check for internal debris.

Good tear down video.

BTW another source for parts is a quiet uses AirSense 10 or AirCurve 10. The model doesn't matter, the parts are all the same.
