PR APAP weirdness was:PR System One machines not true APAPs

A modem would be attached to the back of the blower unit and it would cover the SD card slot if I recall correctly.

Can you easily get to the SD card without removing anything? If so, then the machine probably does not have a modem attached to it.

If you can get to the SD card, I'd suggest looking at the data in SleepyHead. If the machine is adjusting the pressure, the pressure adjustments will show up in SH.

So I'm still puzzled as to exactly what issue hubby seems to be experiencing. I'm tempted to say I'll ask him to observe more and give a better description, but I'm worried that it could lead to him overanalyzing when he's supposed to be falling asleep.

Yep. I'm definitely guilty of over analyzing at times myself. Although in my case, it's a constant worry/irrational fear that the pressure is at it's max (with is only 2cm above where it starts) and that I'm going to get aerophagia. But it's the flip side of the same problem. For a long time I was very, very sensitive to the machine raising the pressure when I was semi-asleep and could tell when it was at 8cm instead of 6cm. Now? I really can't tell that anymore.

If I get more data from him on what's going on I may revisit this, otherwise I think I'll just leave it for now as long as his numbers are good and he's feeling good.

Feeling good with good data is really a sign that things with therapy are NOT broken.

Yes, I can get to the SD card quite easily. I've looked in SH, and it is adjusting, so all seems to be okay there. I'm not sure why he's getting this feeling that something noticably changed, though...

Indeed. I mostly want to make sure we fully understand how the machine works before our trial is over and we make the decision as to which brand/model to purchase. If it was going to go into a CPAP mode, that was going to not be in its favour. But it seems like something else is going on. Whether actual or psychosomatic, now that's another question entirely.

If you get a full-time auto, you can run it in either straight cpap mode or on auto.
--and you can change it any time you like. Two machines in one.
One of the DME's was bad-mouthing apaps during his presentation and I asked him
to tell me (in front of the entire user group) if any auto could NOT be set to straight cpap. (they all can)
--You could literally hear bacon cooking inside his brain!

LOL!!!

The PR modem will cover the SD card port and have a little stubby black antenna sticking up.

Also, if your husband wakes up and feels like he's fighting with the machine, he should press the ramp button. That'll get it to back off to its initial setting.

I sometimes use that when mine gets confused by the sudden change in breathing pattern when I wake up, or if I'm having trouble falling back asleep. This sometimes results in a single brief hypopnea, but that's not a bad trade-off.

You can also do this even if you don't have a ramp turned on. I have a range of 11-17, and sometimes I will wake up and realize the pressure is up higher, maybe in the 15 range. Since I am awake, I don't need it that high now, so I turn it off and on again to make it go back to 11, and then I can drift off to sleep again.

Good point. Turning off and back on is another way to get it to reset.

But that does light up the display and (at least on the ASVs) beeps. I think all the non-ASVs can turn off the on/off beep.
