Flow Limitation Statistics Interpretation
In general, Any flow limitation showing up in the median statistic is a significant problem.
95% Flow Limitation Interpretation
> 0.2 Needs more pressure or pressure support
< 0.15 Marginal
0.1 Good
< 0.05 Excellent and rarely associated with other therapy problems
I am in mobile at work but just wanted to pop in first of all, thank everyone for taking the time to interpret my charts. I find it interesting, especially the goal of not waking up, as simple as it sounds.
Last night, I moved the pressure to 7 and it didn't feel right so I moved back to 8 as the night before. I kept the EPR at 2.
My breathing did not feel as free as the night prior but still better. I spent a few minutes trying to different mask adjustments and seemed to find a good spot.
I am convinced these settings are making a difference, but I'm going to look further into those videos suggested earlier to make sure I have the mask fitted correctly.
This evening I will post last night's chart.
Thanks again eceryone
I thought the minimum pressure of 7cm would be to low, even 8 might have been low with EPR of 3.
Consider 8.6 as a minimum ,but put EPR back to 3 if your flow limits are above 0.2.
Raise the minimum pressure a bit higher if you feel starved for air.
If your flow limits are below 0.2, then leave EPR alone.
Good luck .
Here is last night's chart. I should note that my mask came off, for how long, I don't know. I'm guessing you will be able to tell when that was; I can't, but you could ;-)
I did sleep though the night again, with the mask on, sans the above mention. I am taking that as encouraging news.

Last night's chart. I was able to sleep and keep the mask on for the third night. You might be on to something here.
it is still a tiny bit resistant during exhale when I first lie down but eases after my breathing steadies. During the night I don't have to fidget near as much as I did, but still sometimes feels like a bit hard to exhale. Hard isn't the right word, maybe annoyance, However, those occasions are still few and I haven't had to have restroom breaks which is weird since I drink a lot of water, but I am all for not getting up.
Looking at this chart, the flow rate is .37 under the 99.5$ column. Is that what I should be using to judge regarding your comment?
I have been at 8 and EPR 2, so you think I should go to 8.6 and EPR to 3?
I've not had time to learn how to interpret this data yet, but do I have a leakage issue, or does the mask seem to be fitting well based on what you see?

RE: Posted a while back, still haven't slept
Look at the smooth breathes after 3:40 and after 6:10, that is a goal of light sleep. You had positional apnea after 2:30 you airway got kinked like a garden hose, no amount of pressure increase would help and the high pressure might have caused leaks and woke you up. EPR of 3 may make it easier to exhale. If you feel starved for air ,bump up the minimum .
positional apnea? Thats a new one lol
I'm a side sleeper, so that is not surprising to me.
What level is bump up to the minimum if I feel I need more air?
Other than those spots, does it appear I have any leaks consistent with an ill fitting mask?
