Need a little help

[Billyboy]

I haven't posted in quite some time. I was using a resmed malibu bilevel machine set IPAP 17.6,EPAP 11.6, PS 6.0 for about 1and1/2 year. I have Resscan 3.3 and a serial crossover cable to download data. My ahi was usually around 5 which was mostly hi. The malibu was loud but very comfortable and my 95th percentile pressure (average for 1 yr) was 13.6. My malibu broke and the supplier replaced it with a Resmed Vpap auto 25 which I'm sure is a better machine if I can get it set correctly. The medical supplier set the new machine IPAP 17, EPAP 11, PS 5 in spontaneous mode whereas I was running the malibu in Vast. I changed it to auto and now it is blowing my head off and aha is now around 12. My 95the percentile pressure is now 16.2 which I guess it should be with EPAP 11 and PS 5. I just don't understand how the malibu got 13.6 with a EPAP 11.6 and PS 6 ? I bought a asc acr 38 card reader that I can't make work although the asc utility sees the card Resscan 3.3 does not. I have been trying( for 3 days) IPAP 14.4 EPAP 11.4 and PS 2.6 and am getting a 95th pressure of 14.2 and an ahi around 6. Not too bad but I find the lack of pressure drop on EPAP somewhat uncomfortable and I am waking up alot during the night. Does anyone know if Resscan 3.3 will recognize the Vpap auto 25 card(I have tried the asc drivers for windows xp)? Am I just going to have to get use to a low PS with this machine cause I think i need the EPAP near 11.6-12.0 (that gave me the best ahi on the malibu)? Do you think that the malibu used the PS setting as a maximum PS and it allowed IPAP and EPAP to run closer together than 6? Thanks for any insight you can give me.

I suggest you add VPAP AUTO to the title to attract the attention of those with that sort of knowledge
