You can clone the SD card on a computer. You just need 2 USB SD card readers. A simple copy from the machine card to a blank card is all that's needed.

1. I didn't say this was intended to diagnose or test the machine. Only to verify that the hose sensor and heater are still connected and not shorted. There aren't many failure modes for these things and if the resistances are correct it's almost certain the hose is OK. It's just a go/no go hose tes...

Hose failures have come up off and on. I just went through a batch of about 10 hoses to check them electrically and thought I'd pass on my procedure. Note that I've never found a test procedure from Resmed, this is purely my invention. Note that I was testing S10 hoses, but the S11 hoses should be t...

Regarding the deviated septum. If you can't breath through one nostril by all means get the surgery. I had septum & turbinate surgery a few years ago, trust me, breathing is better than not. I had issues with nasal congestion and still do. The difference is that I never get to the point where air do...

Ignoring the discussion on taxes and insurance. I've had 8 machines over the years. 3 were through insurance the rest I purchased out of pocket, used or new. Nothing wrong with rent to own if your insurance picks up the rental and copay, you can always change suppliers for supplies later on. But if ...

What kind of failures are you having? My 10 series hoses last pretty much forever.

Good point.

I've replaced my machine 3 times with insurance, twice with corporate and the 3rd with Medicare. A sleep study was required in every time to get insurance coverage. In each case I had years of documented compliance. I think it depends on the insurance policy. Its possible that Medicare would have co...

I have an old Respironics M Series Auto SV machine from the early 2000's that I haven't used for a long time. Does anyone want it? I'll give it free to anyone who will pick it up in northern New Jersey. I'd be willing to take it to UPS for packing and shipping if we can work out how to pay for it. I...

A travel CPAP is much better for battery operation than a full size machine so it makes sense as a backup. I have a very old Z1 that I use for air travel. Its not a great machine, dumb constant pressure, but gets the job done well enough for a few nights. I had an Apex machine 15 years ago or so, bu...

A second machine is a good idea if you don't mind the cost. First it will serve you well when you travel. I've killed more than one full size machine traveling, the dedicated travel machines hold up better. The second reason is to have a backup. It can be a long process to get a replacement machine ...

Resmed makes a battery backup, and there are somewhat less expensive 3rd party battery backups. You can leave the machine plugged into the battery, with a power supply plugged in to charge it. When the power goes off the CPAP will continue to run on battery, which will then start recharging as soon ...

I know this is an old thread, but using the Dreamwear headgear on the P30i and N30i is a huge improvement. I've been using both of these masks with the Dreamwear side pieces for quite a while, I couldn't stop the strap from slipping up with the standard strap. I'm now using a further improvement tha...

I suffer from CPAP triggered rhinitis as well. But I'm not especially concerned about the machine. There is an NIH study that showed no correlation between patients with measurable bacterial contamination in their machine and chronic rhinosinusitis. The study is published online, "Association of CPA...

For less than $200 you can get a sleep study online. They send you the hardware, you take the test, then you get an evaluation from a board certified sleep physician. There is a pretty wide selection of providers for this. My wife had very few symptoms other than daytime sleepiness. I arranged the t...
