Overall, the leak line is pretty good. Except for the period between about 0:10 and 0:40, your leak line is pretty much right where it should be:vidiot wrote:II am having a lot of leaks that are waking me up. From what I read, this may not be unusual. If so, just tell me so.
But perhaps here in the data is something useful you can tell me that I can change. [\quote]I'm working on the theory that it's the increase in pressure (or the increased exhaust flow that comes with the increase in pressure) that's waking you up. Which leads to the question: Why is the machine deciding you need more pressure and rather aggressively increasing the pressure?
In other words, I'd be interested in seeing a zoomed in version of the wave flow data, the leak data, and the pressure level data for the following time periods:
1) The big real leak that occurs at 0:10 to 0:40.
2) The pressure increase between 3:00 and 3:20. (There's a clear wake since you turn the machine off and on at the end of this period.)
3) The pressure increase between 3:30 and 3:55. (There's a clear wake since you turn the machine off and on at the end of this period.)
4) The pressure increase between 4:00 and 4:20. (There's a clear wake since you turn the machine off and on at the end of this period.)
5) The pressure increase between 4:20 and 4:45. (You don't appear to wake up at the end of this pressure increase. However, it looks like you may have been awake during most of this time period.

I'm not sure how to do that on my machine. I can't find a setting for it. Could it be disabled by my DME?jweeks wrote:Hi,
If you look closely at the pressure level when each of the events occurs, notice that the majority of events happen when the pressure is at 5, and events mostly stop happening after the pressure goes up to as little as 6. This suggests that your lower pressure is too low. If this was my data, I would consider moving it up to 6 or 7.

Good tutorial here (I believe your machine is the last one on the page, scroll down): http://www.cpaplibrary.com/machines.htmlvidiot wrote:I'm not sure how to do that on my machine. I can't find a setting for it. Could it be disabled by my DME?jweeks wrote:Hi,

The upper (greenish) leak line is TOTAL leaks and this includes the intentional venting from the mask so that you do not rebreathe CO2. The TOTAL leak line is nice and flat except for than one 30-minute bump that starts a bit after midnight AND it's about where we would expect the TOTAL leak line to be for someone using your mask. Note that when the pressure increases, we expect a corresponding increase in TOTAL leaks because the built-in leak rate increases as pressure increases. The TOTAL leak increases between 3:00 and 3:20, between 3:30 and 3:55, between 4:00 and 4:20, and bewteen 4:20 and 4:45 all appear to be nothing more than "increased INTENTIONAL vent rates caused by the increase in pressure
The lower (purple) leak line is EXCESS leak (the bad kind). And except for that one 30-minute period, it's hovering right around 0.0 L/min.
So if it's UNINTENTIONAL leaks that are waking you up, then those leaks are for the most part small enough to NOT be flagged as significant amounts of UNITENTIONAL leaking. And even the largest and longest of your leaks---the 30-minute leak between between 0:10 an 0:40 is relatively speaking not all that large. If you looked at this night in Encore Basic, my guess is that Encore would not flag any of your leaks as Large Leaks---leaks that are large enough to cause the machine problems with its algorithms, both for increasing or decreasing the pressure AND for flagging events.
That's not to say that leaks might be causing you problems.
When a leak wakes you up, where is the leak coming from? Is it possible that what you're identifying as a "leak waking you up" is simply the increase in the exhaust flow once the pressure is starting to increase?
