EncorePro Analyzer, and half-point pressures??

Is EncorePro Analyzer capable of indicating half-point pressures in its graphs? (e.g., 5.0, 5.5, 6.0, 6.5 cm, etc, not just 5.0, 6.0, 7.0...)

This bug annoys me. I once experimented with my (straight CPAP) pressure from 6 to 6.5. I was just testing to see if the titrated pressure seemed OK. As it turns out, things were worse at 6.5, so I returned to the original 6.0 pressure. However, in the pressure charts, 6.5 shows as "7." It doesn't really bother me functionally right now, since it's just cosmetic. However, it is worthless when it comes to showing to doctors, though. Also, if I had upped my pressure to 7.0, then I have to wonder if it would be grouping the 6.5 and 7.0 numbers together, making it a completely meaningless bar graph.

That said, it's a cool program.

Encore Pro also rounds values up, probably has more to do with how the data gets displayed in graphs,

from the looks of those reports, your ideal pressure is slightly over 9 cm to about 9.5 vs 5.0 to 6.0.

Those hypopnea runs appear to correspond with with REM since they show up every 90 minutes or so.

Sadly I'm not able to show half points. This is not a problem with EPA but with how encore pro stores pressure values in its database. The Histogram table being used to build this graph stores the pressures as a tinyint (1 byte) value.

I too had thought I needed higher pressures to chase away the Apneas/Hypopneas, but my Sleep Dr liked my APNEA events best around 5cm; apparently at the higher pressures (8-9-10cm or so), although my Hypopneas drop off, the Apneas increase slightly, and she believes them to be CENTRAL APNEAS... So overall, she wants me to stay away from the higher pressures, and accept the (relatively) few Hypopneas that occur at the lower levels.

I think I feel better at 5-6 than I did at the higher pressures, and I attribute that to the lightening of the Hypopnea pattern. If I can continue to reduce the Hypopnea pattern, I think I'll finally get a decent night's sleep -- I agree that they probably are related to REM, and my guess is they're preventing me from getting continuous deep sleep.
But I don't know which direction to head anymore...

Looks pretty simple to me.......and like Snoredog said, 9 - 9.5 is your best pressure.

Kinda hard to come up with more to add to that.

Jeez. I was pointing out that my Dr placed a higher emphasis on avoiding an increase -- however slight -- in the APNEAS (supported by the Data), even at the cost of higher Hypopneas.
Perhaps you were looking at the bold red graph line (total AHI) and IGNORED the less-noticeable black line showing Apneas, which data does show a steady rise after 5-6?

Since she believes the additional Apneas were CENTRAL Apneas, which are more worrisome, out of simple caution I'm inclined to believe her -- as well as the DATA. My point was that within the lower ranges, certain pressure settings have improved the Hypopneas and not increased the Apneas. I was looking for suggestions that would further refine that, I wasn't looking to give myself Central Apneas...

Perhaps you need a different doctor. Or, just keep your pressure at those lower levels.

You asked the question.....you got an answer.....and didn't like it.
It's YOUR therapy.

You're right... Sorry for bothering any of you.
Have a Merry Christmas!
