How do my charts look? - EE13 - 08-30-2024
I'm getting a lot of events throughout the night and don't wake up feeling well rested. How would you say my charts look? Can you recommend any changes?
RE: How do my charts look? - quiescence at last - 08-30-2024
If this were my charts, I would look at flow limitations as one focus area. Setting the EPR from 2 to 3 is one way to impact flow limitations to the better (usually).
Another focus area would be setting of min pressure. I would note that the machine wants to increase pressure as little as it can but gets really out of hand once in a while. The pressure the machine is at when it does react seems rarely to be below about 9.0. and setting the min pressure above 9 is rational, I would select 9.4.
Setting the maximum pressure level to a pressure I could endure and sleep through is a worthwhile action for as long as seems necessary. Looking at these charts, I would note that the over-reactions of the machine pushed only to shy of 14, but I experienced waking and feel bloated and burpy. I would change the max at about 12.0 to see if my bloated feeling fades or is eliminated.
Last and usually heard comment is turn the ramp off. but - I feel like I get slammed when the machine starts up with wiggly and harsh pressures. So, I decide to set the ramp to be 10 minutes long and start at 6.0. That seems to sneak up on the min pressure of 9.4 while also feeling comfortable enough to nod off to sleep.
Good Luck

I would start with the following settings
EPR full time set to 3
Min 8 - see how you do on that It would be raised depending on how you do at 8.

Along with a pressure increase to 8cm or 9cm and 3 EPR I would also set your machines response setting to standard rather than soft .
RE: How do my charts look? - EE13 - 08-31-2024
Thanks, Old Steve. I'm not familiar with that setting. Would you mind explaining why you recommend changing from soft to standard response, so I can learn about the changes I'm making?
RE: How do my charts look? - staceyburke - 08-31-2024
The regular will more quickly react to your O and H events. The “soft” setting was used in the “for her” machine and now it is in the regular machine now. I have never used it so I can’t recommend it or not recommend.
RE: How do my charts look? - EE13 - 09-08-2024
Here's my most recent chart with min set to 9.6. I went with EPR 1 because I don't mind the pressure when exhaling, but do you think it would improve my sleep if I increased it to 3? When set at 3 in the past, I had a large number of CAs, so that's my concern with changing it.
How do things look? What else do you recommend?
RE: How do my charts look? - Old Steve - 09-09-2024
It appears as though you could still add some more minimum pressure. I would try adding another 1cm to start and also raise your EPR to 2. Try for a few days and see how you do.
Good luck.

hope you are doing better. The flow limitations seem within a reasonable level, so does not need additional EPR just to combat this.
For Sep 07 chart, your flow limitations 95% value at or under 0.10 is good enough from my view.
