RE: ResMed AS 10 vs. Respironics Dream Station
To increase the starting pressure you will increase the EPAP setting. The PS is a constant delta (difference) in pressures between EPAP and IPAP.
RE: ResMed AS 10 vs. Respironics Dream Station
On the Resmed Vauto, you need EPAP min 6.0 to knock out the OA. Everything else will follow. If you want to try fixed pressure in bilevel to reduce disruption, either use S-mode wtih EPAP 6.0, IPAP 10.0 or in Vauto mode EPAP min 6.0, PS 4.0 IPAP max 10.0.

RE: ResMed AS 10 vs. Respironics Dream Station
How does the "number of events" per night relate to AHI? If my AHI = 0.15, how many "events" am I having and what is meant by "events" ?
RE: ResMed AS 10 vs. Respironics Dream Station
AHI is an average while an event would be any obstruction.
Apnea-Hypopnea Index (AHI) measures sleep apnea severity. The AHI is the sum of the number of apneas (pauses in breathing) plus the number of hypopneas (periods of shallow breathing) that occur, on average, each hour.
RE: ResMed AS 10 vs. Respironics Dream Station
An event is typically referring to an apnea. Full apneas are 10 or more seconds in length. However, flow limits are not timed. AHI factors in sleep session time and how many events you've had over that time.

RE: ResMed AS 10 vs. Respironics Dream Station
To determine how many events you had for a sleep session with an AHI of .15, multiply this value by the total numbers of hours in a sleep session, .15 x 6.7-hours =1 event
The price for the 4 GB SD cards seem rather high. Look for the best price on any SD card at or below 32 GB in size.

Ok, thanks for the help, usually my 95% is 11cm and under. So if i bump the EPAP up to 6 and keep the ps at 10 it will be the lowest min it will go? If the IPAP is 10 max won't it not go past that? I am trying to use this as an apap with a little more relief on the exhale.
RE: ResMed AS 10 vs. Respironics Dream Station
Whatever is set for Max IPAP that's all the further up it can go. In Sleeprider's suggestion, EPAP was 6, plus 4 PS, then it goes to 10 on IPAP. That appears to be a fixed 10/6 then in that case.

You want upper and lower limits based on what you can tolerate AND what you need in order to minimize sleep disruption (events significant enough to cause you to begin to awaken or to actually awaken fully). We all vary in what we find works for us for the lowest pressure that still keeps us breathing freely, but for the vast majority of us, about 6 cm H2O is it. I happen to be okay at 5.6. Then as we inhale next, we need an upper limit to pressure, and that also varies. For straight CPAP breathers, no fancy adjustments in pressure needed here and there, my own upper limit is 8.0. It seems you need 11 more than a few times each night.
What you do not want to do is to 'clip' the range of the pressure relief if you have any. So, if you agree with those advising you that you need EPR of 4.0, but you set your lower and upper limits to 6.0 and 9.0, you only have 3 of the 4 relief units left between those two numbers. This is a mistake. Your range has to be, at a minimum, 6 and 10 because the difference allows the 4 units of EPR you have agreed to set. You COULD go up to 12, 15, or 20, depending on your need and what your machine can deliver (the ASV can go higher), but it isn't necessary to allow your machine to go that high according to your historical information. Whatever range you allow your machine, we advise against a lower limit less than about 6.0, with some minor variance, and you should set your machine to go as high as you need it to during inhalation. But if you set any value for EPR, make sure there is room for that full effect between the numbers representing the higher and lower limits.
