Help Interpreting Data

[jlwalker11a]

I've attached a screenshot and think I did the proper organizing.

I'm new to this so not sure how to interpret data.

Thanks for the help!

Based on this one example, your therapy looks pretty good. Your settings are at 5.0 to 10.0 with EPR at 3 and a ramp 4.0 on auto, so minimum pressure is too low for the EPR setting. We try to to set minimum pressure equal to the minimum pressure the machine is capable of plus the pressure reduction setting for EPR. For EPR 3, that means a minimum pressure of 7.0 which results in the bilevel pressure of 7.0/4.0 (inhale/exhale). By doing this, the auto CPAP algorithm can increase the minimum exhale pressure (EPAP) when it detects obstruction. In every case where your chart shows an obstructive event, your pressure is less than 7 and the machine takes time to increase pressure to increase EPAP which is how we prevent OA events. The recommended settings for you are minimum pressure 7.0, maximum pressure 10.0 with EPR 3 which gives a range of 7.0/4.0 to 10.0/7.0. That should reduce events. That is not particularly high pressure, but I don't know what your experience is with starting at 7.0 cm pressure. If you tolerate that comfortably, then turn off ramp and use that pressure. If not, then we should discuss further.

Ok. You can move this thread. My apologies for posting in incorrect forum.

Thanks for such a complete answer. I’ll use that setting for a few nights then post the new results.

Should I also leave Ramp Pressure at 4? Or change that to 7 also?

[Sleeprider]

The use of ramp is for those that cannot tolerate CPAP pressure to start, and need lower pressure to go to sleep. Ideal is to turn off ramp, but if you need it, set to the highest pressure you tolerate.

This is the data from last night.

Should I raise the pressure upper limit from 10 to 11?

[Sleeprider]

Your event rate is about 1 every 2-hours. Pretty darn good! Current pressure is 7.0 to 10.0, and I think I would raise minimum to 8.0 and maximum to 11.0. Well done!

Thanks for that help!

These are the last 2 nights after changing that to 8-11.

The first didn't look great, but last night looked really well I thought.

The main difference was on the first night you had minor positional cluster of OA and that resolved the second night. Note the events occurred for no reason in pairs. That is usually positional or chin tucking. Not a big deal. With your excellent results, we’re mostly concerned with comfort and sleep quality.
