If you don't have any large leaks then they may not show up on the graphs but if they do it is on the very top of the events graph...top right and called LL.

Ok, I do have that, on some of my graphs, posted above. My latest on, June 21, has Large Leaks: .89 under the hours column.
Does that mean I had large leaks for that long?

No. That isn't the number of hours despite being seen sort of under the hours column. None of those numbers in the colored boxes are hours...they are indexes or hourly averages.
You can zoom in on the time frame and count the minutes where the LL is flagged and come up with an approx number of minutes total but it isn't a huge amount of time. Maybe 8 or 9 minutes total would be my guess. Out of 8 hours of sleep on the machine...not enough to worry about.

I see it, I see it! Thanks so much. The light finally went off, lol.

What is a not-so-good amount of large leaks time?

I'm feeling so much better with using the machine. It was one month on June 21. It was a rough start but now I look forward to it, and have been using for naps as well.
My last nap of just about an hour, had an AHI of .44 which makes me a happy camper.

In looking at some other posted data with flagged large leaks, I think that the number you are talking about gives the percentage of time spent in large leak territory. So in your case the .89 means that your leak was in large leak territory for 0.89% of the night. The night that happened, it looks like you used the machine for 6:46:39, or
6.7775 hours. And 0.89% of 6.775 hours is:

• [(0.0089 * 6.775) hours = 0.06 hours = (0.06 hours * 60 minutes/hour) = 3.6 minutes

[/list]

As Pugsy said: 3.6 minutes of time in LL out of 6.775 hours of usage is a trivial amount of LL time and you don't really need to worry about it.

Congrats, LookingEast! It sounds like you turned the corner in getting used to CPAP very quickly! Nice work.

Thanks, Nick Danger. I'm really hoping things stay this way. I'm also sleeping more than 4 hours at a shot too, omg. What next?

Very intrigued by this thread.

Is it normal for AHI to spike as you wake up? When I wake up at 2am, my AHI has been averaging 3-5. But when I wake up a few hours later, it's in the 8-10 range. It looks like all the charts in this thread show the same pattern.

What software does everyone have to generate this data? I'd like to see all those details for my sleep patterns. I have Windows and a Mac.

Thanks for the education!
