ResMed S9 Autoset issues

Have this APAP that I think is losing it's mind. It's never been my favorite, but now, I find that sometimes when I'm breathing in, the pressure goes way up.. like blows the mask away from my face! Also, I often find that if my breathing slows, as in I'm really relaxing and falling asleep, that the mask 'vibrates' (don't know how else to put it), almost like the pressure is 'cycling' very fast, up and down, which then wakes me up. Sometimes I feel like the pressure is almost too much, then other times, I'm damn near suffocating.. This unit is almost 3 years old so it's out of warranty and I will not return to the idiots that sold me the machine. It's an all of a sudden thing.

Any ideas? I've unplugged the device, hoping to reset it.. same issues. I have also removed the H51 humidifier and used the non-heated hose.. this has not resolved the issue.

Are you using software?
What are ALL of your settings?
Did you get a new mask?
Did you change any settings?

We have no idea of what you're experiencing by your description. Could be a malfunction, could be a "settings" problem or any number of things. If you can't use the DME (brick and mortar dealer/store) that sold it to you to check the machine, you can test the output with a homemade "manometer" or purchase a gauge manometer from CPAP.COM for about $78.00.
I have one of those and have used some of the other methods.
Be sure to set the machine for single pressure when you're trying to test the output.

Are you using software?I assume no? At least not that wasn't included in the machine programming.

What are ALL of your settings?
Pressure is 12.. No Ramp.. No humidity.. No heat to hose or air.. mask type is full face.

Did you get a new mask?3-4 months ago I switched from a nasal mask to a total face mask. Changed the mask type on the machine. After some fitting woes and adjustments, has been working.

Did you change any settings?Only those mentioned above. The machine 'says' it's putting out 12.. but who knows.

Like I said, this started 'all of a sudden'.. like the programming is screwed somewhere.

We have no idea of what you're experiencing by your description. What else do you need to know? Like I said, it's just odd, one minute the mask is 'blowing off my face' the next minute, not.. then if I start to relax (or stop breathing on purpose), the mask literally 'vibrates' on my face..

It's like the 'auto' part is not reading the pressures or working like it should. At it's 'worst'.. when I inhale, the pressure nearly blows the mask off, but then when I exhale, the pressure disappears. So it's like the 'sense' part isn't working right, like it's 'over compensating'.

One question, can I turn this feature off and just have the thing work as a 'normal' CPAP? If it just blew the pressure, that would be great for me. I don't need the 'breath more natural' part of the APAP..

YES...You can turn the auto off....If the pressure is 12, it sounds like it is off...otherwise you would have a min/max pressure...are you using EPR? Are you really familiar with the feature/settings on your machine?

OK. If you don't have a manometer, you can check the output pretty simply.

Check out this thread and especially the method described by "tomjax".
All you need is a bucket of water and a ruler that has centimeters marked on it. Take the ruler and mark the hose at 12 cm. with something like a Sharpie marker. You can also tape the ruler to the hose to give it a little stiffness while you hold it in the bucket of water. Make sure you have the hose in the water below the 12 cm. marker BEFORE you turn on the machine.

Back in 2010, I purchased a "never used" CPAP and found it had a broken hose nipple inside. The broken part was what should have helped regulate the pressure. But, since it was broken, the pressure would keep climbing until the mask blew off of my face. I took the machine apart, found the part that needed to be fixed or replaced and did so fairly cheaply.

I do not know if I am using EPR... I assume YES, and that's what's going nuts on the machine?

It's how they set it up.. they failed this in so many ways.. I refuse to deal with them anymore.

I would love to just have this operate as a dumb CPAP, without all this BS garbage it came with.

It's long past time that YOU took control of YOUR own therapy.

I'll just add that if you do not currently have a back-up pap machine, now might be a good time to consider obtaining one. As you've just experienced...........stuff happens.......frequently without warning. Good luck !

A big +1 on that!

You have been using this machine for 3 Years....It's about time you took an interest and learned how your machine operates. It's not the DMEs responsibility after they sell you a machine.....As Den said...Take some responsibility...I'll bet you don't even know what EPR is.

I do have an interest, and yes I know what EPR is.. like I said above, that is the programming / sensors I thought was the problem! But I've been through the menus several times and if you're at all familiar with this machine, you know how damn DUMB they are. There's 4 settings, Mask Fit, Mask Type, Temp, and Ramp.. that's it. Also, up until a few weeks ago, the machine has performed ok.. so I didn't mess with it. I really appreciate the help, but please don't mow me down because of a lack of knowledge. Certainly each of you were at one time where I am? In my defense, I (and my wife who uses a cpap) were BOTH told by the DME company that changing any settings or making adjustments would VOID our warranty, and break Federal law. So I was not eager to do that.. I now know that isn't the case. One more reason that I'm glad I told the DME company to stick it up their arse!

Thanks again for your help and suggestions.

You need to read the manual and you will see that there's a LOT more to this machine.

When I bought my machine from CPAP.COM in April of 2005, I set the machine up myself......and to the settings I felt would work better than the ones my doctor prescribed........which were not usable.

And, as you've apparently discovered, what that DME told you is an absolute and outright LIE. THEY can't change the settings without a doctor's order, but it doesn't apply to the owner/user of the machine. And, it absolutely wouldn't affect the warranty one little bit. If you've had this machine for almost three years, it's been out of warranty for nearly one year.
