I've been using the RemStar 510M for over 19,000 hours and it has been acting up for a few months now. When starting up it will sound like the blower is starting then it will fizzle out and you can see the device reboot. Eventually it gets started. It does this once and while but has been happening ...

Your profile now shows a REMstar M series CPAP. There are multiple versions of that machine. Some versions will run the humidifier off of 12V, some require 120VAC for the humidifier. Most UPSs and standby AC supplies don't supply proper 120VAC power, but what's called Modified Sine Wave (MSW) power...

I went through a lot of John's guide and considered putting something like that together, but it is very heavy and bulky, and I don't like the chance of fumes even in the case if I can avoid it. Your main choices of battery are lead acid or some form of lithium battery. On rare occasions, lead acid...

... Is a big no no to lower the setting to say 12-15 and see if my AHI stays considerably below 5? ... Nope. But be certain to monitor carefully, can change only one thing at a time. Changing too much or not too frequently can confuse the situation. But don't be too surprised if your AHI score clim...

amazon.com sells the duracell 600 which is a solid backup battery that will run 10+ hrs of cpap without humidifier. And it's reasonably priced. i've used in for several power outages and never a problem. http://www.amazon.com/Duracell-DPP-600HD-Powerpack-Starter-Emergency/dp/B000TKHMWK/ref=sr_1_1?i...

Any AHI of 5 or less is considered "normal" and does not require any further tweaking. Of course, if you no longer feel as rested, you might want to talk with your sleep doctor about it. But normally that's a great reading and should not require a new sleep study. Hope that helps. Thanks again for ...

Rested Gal has a thread that she maintains about Battery Backup setups. I also put together the following thread on a Battery Backup Design: http://www.cpaptalk.com/viewtopic.php?t=49115 Hope that helps. Do you have a link to her post, I can't seem to find it. Also, I had a few other questions. I a...

What they said. Also, no free lunches when it comes to weight or other tradeoffs. Your lightest, most efficient, and most trouble-free configuration will be running your Cpap directly off a battery (assuming it can run directly off 12 volts); worst in all those categories will be running it off a U...

I updated it, I picked one that looked like it, but I have the right one now.

I've been using my CPAP for a few years now and I am quite used to it. When I lose power though, it has become a problem. I have looked in the past for a battery option, I know there is the CPAP one for $300 that claims to get 12.73Hr on my device and my setting (17). I was looking for a cheaper alt...
