Help! Changed CPAP Settings, Now Machine Not Working
#1
I have Philips-Respironics DreamStation Auto CPAP that I've been using for just over two months. It's been life-changing! Anyway, I've been battling leaks and tried everything to solve this. Various mask and headgear options, and even cotton pads. The only variable left was the pressure, which I suspected to be high due to the fact that I am often awakened with the mask blowing away from my face. My Dreammapper software shows that my 90% pressure sits around 12.5 and the max was set at 15. I found an online manual and adjusted the max pressure from 15.0 to 13.0. This is the ONLY setting that I changed.

Last night was absolutely terrible. I woke several times and checked the pressure, which was only at 7.0 - 8.0 each time. My wife says I snored all night. My AHI jumped from my normal range (between 2 and 4) to 21 overnight! I'm in a complete panic because my provider is closed for the weekend and I cannot sleep at all. Any help that can be offered is greatly appreciated.

Hi CJ. First, it would be a tremendous help if you downloaded the free SleepyHead software. The charts show your settings and can help us to troubleshoot any issues. The first two links in my signature describe how to organize SleepyHead data and post the charts to the forum. Aside from that, with a 90% pressure of 12.5 I would be inclined to increase minimum pressure.

Go into settings (control knob + Ramp button), go to Therapy settings, verify mode is AUTOset. Set minimum pressure at 8.0, set maximum pressure at 13.0. Optionally turn ramp off or use AutoRamp with a starting pressure at 6.0 , then exit. Increasing the minimum pressure will make your machine more responsive to your needs, and put pressure closer to your therapy range. Starting at too low of a pressure can be a problem with the Philips machines as they tend to try to maintain pressure too low, and this may be the source of your problem.

If this does not fix the problem, you can set mode to CPAP and pressure to 12.0 or 12.5. If you can download the software, the data will reveal if your settings are not what you expect.

Hello cj and welcome to the forum, go ahead and work your way through the steps recommended by Sleeprider including getting set up with Sleepy Head. If you follow the links you shouldn't have any problems. Stay with it and ask questions on the forum. Good luck.

Thanks so much for your reply. I just installed SleepyHead and confirmed that my pressure maxed out at 7.0 for the entire night, which is definitely not right or what the CPAP settings indicate. The mode is set to AUTO, as it has been since I received the machine. 

Here's a link to the stats from last night: http://imgur.com/a/18Ftm

I'm just so sorry that I messed with this....I'm in IT, so I can't help myself!

Needless to say, that is not normal operation for the machine.  I would unplug the machine, then re-power it.  Then I would go into settings and reset a few things.  We see that the settings show APAP mode at 6-15.  I would change to 8-15 and verify that it is working properly.  If not, then go to CPAP mode with pressure at 12 and verify operation. 

If this problem continues this is a warranty issue.

Also disable the VS2 (vibratory snoring 2).  It is meaningless (no one is quite sure what it is measuring, but real snoring is not the answer).  Turning it off makes the events cleaner and easier to interpret.

Thanks to everyone for the welcome and for all the helpful information. I'm happy to report that after power cycling the CPAP machine, it operated normally again last night. The max pressure was lower, much less leaking, and my AHI was back in the normal range under 3. Feeling great this morning, thanks to this community!
