[Pressure] Applying APAP Data to CPAP Machine

[OpalRose]

Your doing great.
Let us know how the 9cm works on the ResMed S8.

[Dog Slobber]

Good numbers again last night. I will be traveling today and using my Resmed S8 Elite II tonight. It's a straight pressure CPAP. If I'm reading my results correctly and following the Board's advice, I'm going to set my pressure at 9.0 cmH2O.
Looking forward to seeing how it works for me.

If your minimum with APAP is 9.0 and your device occasionally increases to address events or symptoms of imminent events, then straight 9.0 on CPAP will not address everything.

I think that a better fixed pressure equivalent would be to increase it slightly above your APAP minimum. If your APAP requires an occasional pressure increase to address your therapy needs, how can a fixed pressure at that minimum address our needs?

You're not new, a slight pressure increase won't create a tolerance or leak situation, with APAP you routinely experience pressures up to 11 or 12. I would guess that a better Fixed alternative to 9-13CM would be about 10, maybe 10.5.

I would raise you to 9.6 fixed pressure and use EPR at 2. I actually think it may work even better than your PRS1 Auto.

I would stay with my suggestion on page 2 and say to use the 95% of 11cm on the S8, you could also use it on your auto as min 11 and let the machine move from there on a bad night.

You guys saw it coming. A fixed pressure of 9.0 on my Resmed S8 Elite II CPAP didn't work for me. It gave me an AHI of 4.7. Unfortunately, the machine isn't compatible with OSCAR so I can't post a chart.
I won't be using my Resmed for a while but I'll take your advice and raise the pressure. Will begin at 10.0 and slowly raise it from there.
On the other hand, I'm happy with results I'm getting from my home APAP. I've posted last night to this message. After a week of use without fiddling with any of the settings, things seem to have stabilized. Any thoughts on how I can tweak it further?
Thanks for your insight.

The machine is slow to react, you can see events there that the machine ignores, You could raise the min pressure up 1cm and see what it clears up.

I would not follow ajack's advice and raise pressure any further those spikes in the pressure line is the Philips machine getting bored with nothing going on and testing increased pressure to see if it helps in any way finding it does not and dropping the pressure again. Your AHI of less than 1 is great

I've been put in an awkward position with conflicting advice from two board members that I respect. Not sure what I'm going to do tonight.

As long as you are feeling good, and you are sleeping well, there is no big reason to change your pressure.  

The only thing I see is the Flow Limitations and Snores.  These may be corrected with a slightly higher minimum pressure, but that’s not always a given.  It’s up to you if you want to experiment with that, but if the FL doesn’t bother you, doesn’t keep you awake, then there’s no reason to change pressures.

I can’t remember if you said what your Flex setting was, but I would keep it at either 1 or 2.  

Your AHI is good, you feel good, you sleep well.....

Thanks for bringing sanity to my head.
