PS [Pressure Support]
#61
RE: PS
Here is last night:  https://imgur.com/a/LpXoz  I slept until midnight and then I stayed awake and watched tv for an hour.  When I went back to sleep I didn't use the cervical collar.

What I'm thinking of doing is to go back to the way it was:  Mode = S, IPAP = 14, EPAP = 10. PS = 1.  At least my AHI was a lot better (around 2.5).

RE: PS
Now I'm really messed up.  Here is last night:   https://imgur.com/a/ckTcX

This is terrible.  I made an appointment with my sleep doc but it's not until Feb 13.  I can make it earlier but my wife or I have to drive an hour and a quarter.

RE: PS
Larry, I don't think the PS 4 is doing you any favors. You seem prone to complex apnea, and might be better off back on the Vauto mode at 8-14. If you're into a little experimentation, try PS 1. That is going to be almost like APAP. As I recall, you got pretty good therapy on an auto CPAP previously at 10-14.

RE: PS
Ok.  I'll set it back the way it was yesterday only make the PS 1.  I'll also tighten up the mask a bit.  I called the doc and got to see him 3:50 pm on 1/3 in Lancaster which is a bit closer than Berlin (about 45 min instead of 1 hr 15 min).

RE: PS
Here is last night:  https://imgur.com/a/7K8C6  It is a little better than the previous night.  I think I should increase the pressure, but I'm waiting for your comments.  How about PS?

RE: PS
In VPAP S mode, the PS does not matter because it is set by the fixed IPAP and EPAP pressure. In your case, the current settings of 14/10 result in a PS of 4 regardless of the fact PS is set to 2 in VAuto mode. That is just an error in the Sleepyhead chart machine settings. For fixed VPAP, what you set is what you get. In Vauto mode, you set an EPAP min, PS and IPAP max and the PS is then fixed and pressures vary in the set range with IPAP and EPAP separated by a constant PS.

RE: PS
Larry, I'm frankly a bit perplexed by your current results. The obstructive apnea events call for higher EPAP, and the numerous RERA and hypopnea might respond to more PS. Results posted from December 16 showed quite a bit of central activity that has not been present on most charts. I'm going to go with the assumption you have mostly an obstructive problem and just stick with the titration protocols. You seem to do better on fixed pressure than variable. If you're going to use VPAP-S mode, I might try increasing EPAP by 0.5 and PS by the same, So my suggestion is 15/10.5. Thatis a PS of 4.5 on a slightly higher EPAP.

RE: PS
The chart you displayed was not mine.  I used Auto last night NOT S.  You seems to want me to do S and PS at 4.5 - is that right?  I will switch over to that.
