Yes, it is! Since the min pressure is higher than before, the APAP might be a bit louder and that may be the reason why your husband notice it. Now for the graph, not exactly what I was expecting for your breathing pattern but the cause might be similar. Let the speculation begin... You "might" be to sensitive to pressure changed and the pressure jump that we see in that zoom-in exacerbate/change your breathing pattern to the point of causing a bad hypopneas and apneas cycle. That reminded me of a question I ask before, have you ever been on fixed pressure of 13 (or lower) for at least a week or so in the past?RubySnooze wrote:The night my husband heard me stop breathing was Friday, the 26th. AHI of 12.38.
Here is a zoom shot of that night at 2:40 a.m.:
Your sleep doc competences might be questionable but the sleep tech that did your titration might actually have done a good job!
And as for palerider note on leak, I'm no expert of Respironics leak, but my understanding of Pugsy's comment on your leak was that you where ok for that brand.
If you've never been on fixe pressure before, personally I would try a fixed pressure of 10 for at least 4-5 days. Your AHI isn't that good anyway and the goal would be to try to go to the 13 of your titration. If you start to see higher AHI than usual. i.e if your higher AHI you've seen is near 20s and you're starting to see AHI in the 30s or more for 2-3 days in a row, back off to you current setting until someone can look at your graph. If your AHI start to drop, post the result and we’ll see what’ the best move.
