I am having the same problem with the noise and it is getting worse the longer I have this machine. Julie, you mentioned turning off the c-flex. How do I turn it off? How do I know if I need a c-flex? I do not know what it does?

Good news. I heard from the DME and they are sending me the System One Auto and will set the pressure at my fixed rate of 8. It is supposed to arrive by Monday. I am sure I will have many more questions once I receive it. Thanks to everyone for helping me get the CPAP machine I need. Not worrying ab...

I have spoken to my doctor and he is prescribing the System one Pro. That one also does an auto adjustment for altitude. According to my doctor, I do not need an a CPAP machine that does auto titration since mine is static. What do you all know about the System One Pro?

I am now in the process of talking to my doc and with the DME company to see what is involved to change to the Respronics System One Auto so that I will have the correct altitude settings no matter where I am. The answer I get from the DMe person is that it will depend on whether the doc will write ...

I found the settings for altitude and changed it to 2. Last night I was aware of greater pressure; also the pillows did not slip as they had in the previous nights. Am I correct then in assuming that the change in altitude setting changed the pressure? I am concerned that the machine I have is not a...

I have the Respronics System one Plus. I have been traveling and am now at a higher altitude than when I first got this CPAP machine. My altitude setting is on 1. This machine does not have an auto altitude setting feature . How do I know what altitude range each of the number settings are? Also, ho...

I have been using the Respronics System One with Humidifier for a month now. I have finally adjusted to the headgear of the Swift LT and the whole idea of sleeping with a machine. I am still trying to figure out what the numbers mean. I have a choice of 1,2,3,4, or 5. What is the difference of the n...

Hooray! Great night sleep. No problem with the batteries....last entire night with much room to spare. Thanks to all of you who gave me information and advice. Without you, I probably would have been up all night worrying about the batteries. And even more, I now understand the electrical/battery sy...

Okay, so I will not use the CPAP while driving. Very good advice.......... Tonight is the big night. From what all of you are saying, I should have no problem. The fact is that I have 4 batteries at 225 amps each. Using the " simple " formula and calculating at 180 watts, that is 15 amps. If I sleep...

Brian,
I will let you know how my dry camping adventure goes. I will not be in as beautiful place as BC but will instead be in Mitchel , SD , on Cabellas parking lot. Interestingly though, I am traveling to BC and plan to tour the Vancouver Island for a month or so.

Have fun,
Linda

So, topdragster, if I have 4 batteries with 225 amp hours, then I should not have any problems running the CPaP with humidifier at total 180 watts. Is that correct? I am not sure I know the conversion of how many amp hours are consumed by 180 watts/hr. I installed new batteries last August so I know...

Thanks for all of your input. I do not have any special 12v cables for my Respronics System One C flex machine. I do have an inverter on my motorhome that does convert battery power to electric outlet power (is that 110v?). I will be dry campting in 2 days. I called Respronics and they said that wit...
