New Auto A-flex cpap
#1
Hi there, I just got a new cpap!

Philips Respironics System One RemStar Auto with A-Flex 550p. I picked it up for $150 with just 22 hours of use =D

So my question is, where should I start the pressure range settings? I was set at 11 with my cpap. This being an auto though, should I leave it at 5-20, or should I narrow it further in? My old machine didn't give me any useful data to compare with, so I feel like I am having to baseline from scratch.

I could work with the technicians, but I don't feel like paying my deductible in December. For now, I know I could turn it to cpap mode and leave it at 11 and be ok, but I'd like to try and take advantage of the better technology.

Last night I set it to 7-12. I feel like it worked pretty well, but I'm not sure if the minimum pressure was high enough. My AHI was 3.62, which seems pretty good overall.


I'd love to hear some recommendations.

Id set my min at 9 max about 15
Then monitor data with sleepyhead.
I have the same machine.

A lot of people feel like they can't breathe @5. I'd probably start the minimum pressure at 6 or 7, use it for a few days or a week, then check the data in Sleepyhead and see where it spends most of it's time.

Thanks, that confirms what I was thinking. I'll bump the min to 9 and max to 15 and leave it for a couple nights.

As you get the lower limit closer to where it needs to be, your AHI will probably drop more. If you find the machine bumping into the upper limit, you might want to try raising that a little. The machine won't go there unless it needs to.

The machines try to walk the line between preventing your apneas and waking you up with rapid pressure changes, so the closer it starts to where it needs to be, the better you'll sleep.

Be sure to delete any previous patient content that might be on the machine by getting into the clinical menu (from setup, press ramp and control knob until 2-beeps), then turn to Info and Reset Data. If you don't do this, any therapy sessions that might have been recorded in the short time this was someone elses machine will show up in your data. Good luck!

Thanks for the info! Super helpful each of you!!

Very helpful to know about the minimum. That makes a lot of sense.

I'll make sure to get the data reset. I meant to do that last night but forgot.

Ok, so last night my AHI was down to 2.76! I'm gonna leave the settings where they are for a few more days and see how it works. I wish I could have been able to collect this kind of data before. I am really curious now how this machine performs vs the other one. I will say, I have only been able to judge effectiveness based on how I feel, and I have to say, I think I am feeling better today than I have been... super subjective, I know, but it's something.

One thing you can compare it what the Auto did in terms of pressure, compared to the 11.0 of the old machine. It's not much, but it gives you an idea of how close the old fixed pressure was.
