Are the settings the same? Check the software version. Is that the same? If your AHI is truly better, that's good. But if the newer machine is detecting events that the older machine misses, than that is better.

I assume you are sleeping with someone since you are taking birth control. Ask him if you snore. Ask if the snoring sometimes stops for several second and then you suddenly gasp for air. My father used to shake the whole house, then pause and then gasp loudly. My wife says I did this before CPAP, bu...

Your 5 volt Anker battery pack will not work.

You should look up FAA and airline restrictions on lithium batteries.

Many people use distilled water. But bottled (not distilled) water does not have an advantage over tap water. Mineral water is worse than tap water.

You said you did a continuity test of the fuse. Did you measure the heater resistance?

I believe that the silicone looses flexibility as the more volatile components evaporate. Heat would accelerate, not reverse this. But I am not a chemist.

The 12 volt to 24 volt converter can not be 100% efficient. It is probably 80 to 90% efficient. If you wire the batteries in series, you get 24 volts without any loss. On the other hand, the three batteries will have more energy than two.

I used a Resmed Airsense 10 Autoset for 5 years without any SD card problems. I got a replacement Resmed Airsense 10 Autoset without a card. It apparently reformatted the card when I transferred it from the old to new machine. I should have gotten a new card. I still have the data on Oscar.

I suspect that the plug in the adaptor is loose.

What policies are you referring to?

This is very interesting. But I don't understand it. Are you using it with the Bleep Halo seals? What do the magnets do?

The way a microprocessor updates software is a little bit like a neurosurgeon who operates on his own brain. It is much better for a glitch to abort the process than to make the machine, including the bootloader completely inoperable.

I had a similar experience with a F&P Brevida pillow. I didn't try boiling. I just replaced it. I think the problem was a loss of flexibility caused by sublimation of volatile components in the rubber. Boiling could only make it worse.

Are you saying you are trying to power the CPAP machine with USB? That can't supply enough power. The machine would reset when the motor starts. If you are in an rv, you should be able to get 12 volts.

People hate me for this... but I can recommend Afrin. I hate that you said that. I too found that Afrin was very effective. I would use more when it wore off. But it took less and less time for it to wear off. My congestion and runny nose got worse. It was the Afrin that was causing the problem. I ...
