Suggestions for changing Settings PR 60 Autopap

[dnaonejax]

The Dr said 7 to 12 which I knew was too low:


The Next night I upped it to 8


The I upped it again


Next time left it at 8


Can't seem to get the H number down though?



So I have upped it to 9 and 10 to a max of 15



Setting it at 10 doesnt seem to get rid of the H?

and it can increase CAs?

All I can tell from the wave form reports is that the pressure seems to want to go back to 8 and shortly thereafter a H occurs?







What I am not sure about is whether the higher pressure is waking me up or not?

Any ideas greatly appreciated it.

Would a PR 60 Bi-pap help?

What are you trying to accomplish? Erasing all events? That is really hard to do.
Are you having problems that aren't showing up on the reports? The reports look great on paper.
Trouble sleeping? Waking up and don't know why?
I would have been happy with that 8 cm minimum if it were me and let the machine do its job when it wanted to go higher. It sure doesn't want to spend much time up there.
Both Hyponea and obstructive apnea numbers can vary from night to night without changing a thing and often vary much greater than yours appear to be varying and this is entirely normal because we simply don't sleep the same every night.

Those "centrals" with the minimum of 10...nothing to worry about..you could easily have had them happen at 8 min. Not nearly enough to worry about. They could have been a turn over in bed central...could have been real but either way not nearly enough of them to worry about.

I think there comes a time when we have to sit back and let things settle down and quit changing stuff so quick. We can't make changes based on a night or two of data when we are looking at data that varies so little. Now if your AHI was 8 or 9 yeah, keep working at it but you are already just about as low as we can expect you to go allowing for normal variances.

I once did some experiments with my APAP. I determined that a minimum of 10 gave me consistently 2 or less AHI. I did kind of wonder if going higher would reduce it any more. I started increasing the minimum 0.5 a week (I kept it for 7 nights) and I worked my way up to a minimum of 13 and you know what...that AHI wasn't one bit better than it was at 10 cm minimum.
I had some nights with 0.5 AHI and some nights with 2.4 AHI at ALL the minimum pressures that I tried from 10 up to and including 13. So I went back down to 10 minimum.

Not all higher pressures cause centrals. I routinely see 18 cm and I don't have any more centrals then than I might have with never seeing much of a rise in pressure at all. Only a small percentage of people may develop centrals with cpap pressure and when they do it isn't limited to higher pressures. It can just as easily happen with a pressure of 7 or 8.
There are lots of people using straight cpap at 18 or more and they don't have any problems with centrals.

I don't see any reason to go with a higher minimum in your case but I don't see any reason not to try a little more if you want to see what will happen if that is what you are wanting to do.
Now if the pressure variations were disturbing your sleep...then narrow the range with a little increase in minimum so that you can cover those times when the pressure wants to get up there a bit and have it be less disturbing.
It is possible you know that if you were using straight cpap at 20 that you couldn't eliminate all events if that is what you are trying to do.

Whatever you do...pick something and stick with it for at least a week. The AHI changes you are seeing here could happen without any changes at all. When things are tweaked down to this level (AHI of 0.4 one night at 8 cm) you simply have to give it more time so that you can adequately evaluate the trends.
