Resmed AirFit suddenly upping pressure beyond max after 5min

I've been using a ResMed AirFit for about 8 months now and it just suddenly started turning the pressure up (from 6 to 10) after being on for about 5 min and I CANNOT figure out how to fix it. It's not a ramp setting. I've set it both on the regular mode (where it should just stay on 6) and AutoSet mode (and told it to go "between 6 and 6") and no matter what I do, it changes itself to 10 after a few minutes of sleep.

With the pressure that high, I wake up with horrible gas and take the CPAP off after about an hour, and then I often go back to sleep without remembering taking it off. I feel awful without it. Please tell me one of you has a fix for this error, because I only just figured out what's going on and I don't think anyone will be open to take my calls about it until Monday.

ResMed AirFit is a mask, not a machine. I am mobile so I can't see if you have your machine listed.

Op does not have his equipment listed.

NReed, we CAN help you, but only if we know which machine you are on. Is it ResMed or Respironics? Remove or empty the hunidifier and turn it upside down to tell us the model number.

Also tell us if there is a modem attached.

I suspect either the modem "phones home" and cancels your setting changes or the data card is somehow locked and overriding your changes (assuming you are making the changes correctly). One newbie thought he was changing the pressure but he was really just changing the humidity).

We can help you check the settings once we know what machine you have.

OP probably has auto correct. I think you can reasonably assume the O P has a Resmed Airsense. Please advise accordingly.

generally better not to assume and guess, but to ask for clarification and correct info.

Do you mean you have an Airsense 10? When do the changes take place? Every night or just once?

The A10 automatically sends data to the DME every day unless you turn Airplane mode on. The DME can remotely make changes to your settings. Did the DME initially set it to the pressure that it now goes to (10)?

If you are able to access the clinician menu, is the setting for ramp on "Auto"? If so, that means it will go to the minimum pressure (assuming it is higher than the ramp pressure) when the machine senses you go to sleep. If the minimum pressure is 10 (and the DME is resetting things remotely to the initial settings), that could be your problem.

It would be very helpful if you would fill in the equipment profile so that we know what machine model and mask you are using.

If you have an old machine and it is doing what you describe, I think your machine may need service or replacement. The A10 has been on the market about a year and shouldn't be doing this.

Oops, yeah, it is an AirSense 10.

I think I fixed it; I reset it to defaults and then changed it to what the settings were before.

What it was doing was displaying 6 as the pressure it was supposed to have (next to "Pressure" on the display) and then the pressure would go up to 10 and a 10 would be displayed in the circle in the center of the screen.

If your settings were not set so that your minimum or CPAP pressure is 10, then it sounds as if the machine is defective and you should contact your DME. There is a 2-year warranty on the Airsense 10 machine.

The pressure displayed in the circle is the pressure the machine is blowing at the time.

Well, it worked for a little while doing a reset of the settings on the machine, but now it's doing it again. I guess I'll take it in to the durable medical people tomorrow. Any advice for getting them to do anything? It's Major Medical. I'm probably just gonna show up at their offices and not leave until they help me, since I'm completely miserable and so willing to be as squeaky a wheel as necessary

I would call first, tell them the problem,and see if there will be anyone on hand at the time you plan to go that might be able to fix it. It may be a known glitch. If you just show up there, you may end with the only people there being 2 secretaries / insurance processors who can't help you. The respiratory therapists are often out on appointment. They may give you a loaner machine and send yours back to the manufacturer to fix. I really don't know what the process is. However, I would not waste my time and theirs just showing up. I'm sure they didn't intentionally give you a defective machine.

With the A10, they can remotely check the machine and its settings. There is a possibility that they can do that and save you the trip. Maybe there is a software upgrade that will fix it. Just be sure the machine is on and Airplane mode is Off.

Let us know how it goes.

Alright, so after having a hell of a time getting Rotech (my DME company) to actually HELP me, which required ANOTHER visit to my sleep clinic I FINALLY got the DME to replace the machine.

ANYWAY, I have the new machine, and, lo and behold, IT'S DOING THE THING AGAIN. It isn't just doing it after a few minutes anymore; it seems to just turn the pressure up, for no apparent reason, partway through the night, which of course wakes me up.

I took screenshots of SleepyHead showing what is happening in case anyone can get any information out of that: http://imgur.com/a/HStFj. I'm having a hell of a time getting the medical professionals to even believe this is happening, since it only happens occasionally, for me, when I am actually using it, so if anyone has any insight I'd be hella grateful for it. Again, I have the Resmed AirSense 10 Autoset.

What is your pressure setting supposed to be-- a constant pressure or a range? Do you want to use ramp?

Are you sure the DME did not set you up for a 10-minute ramp of 6, then a pressure of 10? That is what appears to be happening on the 15-minute SH snapshot you posted.

If you made changes to the settings after the DME set up the machine and you are leaving Airplane mode off, the A10 has a modem that sends data to your DME. I have been told the DME can remotely change your settings back to the original settings. I made changes to my settings using the clinician's menu after the DME set up the machine with features that I didn't want. I leave airplane mode "on" most of the time so that the DME can't remotely change my settings back to the settings the DME originally set up. It may be done automatically. I'm not sure.

It definitely isn't set with a pressure setting of 10. When it does this, the screen shows a "10" in the middle of the circle, but the number in the right hand corner, which says "pressure", is still 6. Sleepyhead also indicates that it is set to 6. It is not my doctor, or my DME, changing my settings. The "maybe someone is changing it" thing is what I got from my doc and DME also; I couldn't get them to believe me until I brought in a photo of the screen that showed the pressure was set at 6 but that it was blowing a 10.

Perhaps your DME got a shipment of defective A10 machines. I have the A10. The number in the circle is the actual pressure (10). If you are using a standard A10, maybe ask about getting a "FOr Her" version, or vice versa. Maybe this will get you a machine that is not in the defective group of machines this DME seems to have. Also, do you know for sure the DME gave you a different A10? Is it possible the DME kept it to check it and gave it right back to you? Have you seen the "old" and "new" A10 at the same time? Just trying to think outside the box here, as what you are describing is NOT how an A10 is supposed to work.

I would recommend that NReed post a list of all the settings in both the user and clinician's menus, including submenus (like software version, etc.),

He may also want to call Resmed, if this is an actual software bug. A photograph of the screen showing a set pressure of 6 and an actual of 10 will probably make them take notice, so have that ready to email to the person you're talking to, if you can. Also include the list of settings.

Also, try doing the reset that seemed to fix it, and turn airplane mode ON and see if it still happens (it will complain every time you start it, just ignore it)...
