Sleepyhead data - Help needed please

New to Sleepyhead and trying to interpret the data. I was suspecting leaks and looking at these figures I think my 95% leak rate is consistently too high.
Please could someone take a look? If I am correct, is there any way of telling if it's mask leak or mouth leak?

Screenshots are for the past 7 nights - thank you in advance:

Can you omit the pie chart (turn it off in Preferences/Appearance) so that the overall AHI and those bar graphs are showing.
The pie chart is pretty much useless.
No need to redo these images though. Just mentioning it for future reference and you need to do something a little different with the graphs.
Also you can omit the snore graph as well as one of the pressure graphs. You have too many graphs including which makes some of the more important graphs too tiny to evaluate.
See my examples of how we like to see things in this thread.

There is no way to separate mouth leak from mask movement leak on the reports...leak is leak no matter where it comes from.
The simplest way to tell if someone is mouth breathing for sure...tape the lips shut and if those leaks don't happen and the tape is in place...they are mouth leaks.
Mask movement leaks can look like mouth breathing leaks so the only way to know for sure is to tape the mouth.

I had a hard time with your slideshow...seems like no matter what I selected I kept getting the same report for Mon the 20th.
Maybe if you consider using imgur for hosting the images and then embedding in your post might make it easier.

The one report I kept getting no matter what I selected shows 13% of the time in large leak. While it isn't pretty it still would get you a Mr Smiley face for mask fit.

One thing I noticed is that your pressures are fairly wide open and the large leak time seemed to be associated with much higher pressure times. I am wondering if what you are seeing is mask movement (loss of seal) simply from the higher pressures. You need to look at the other times in large leak and see how they correlate with pressure.
Mask fitting at the lower pressure for a good seal isn't going to necessarily work at higher pressures.
So those leaks may be mask fit and not mouth breathing.

I would do something about the wide open range so that the pressure variations don't change so widely...so that your starting pressure is closer to your needed pressure so that initial mask fit at the higher pressure won't leak so much at the higher pressures. Mask seal is a problem with auto adjusting pressures when the pressure range widely.

Oops, I somehow managed to do the same screenshot 7 times, sorry. I was having a lot of trouble working out how to do it. You have made some interesting observations however. I will try to fix the images later today with your suggestions, many thanks.

Trying to fix things here and getting very frustrated!

No, I went into full screen mode to do the screenshots and now the dropdowns for the top 4 menu buttons are not working!
I have uninstalled and deleted everything SleepyHead, reinstalled and still it's stuck in full screen.

Shit, shit, shit. I wish that little bit of the instructions never even existed. All it does is cause problems.

See this thread.

FWIW....when I had the frozen full screen the only way I could fix it was with changing the desktop resolution so I could then access that menu.
I am using Windows 10 but the problem exists across all operating systems. It's a bug in SH and we should be telling people to NOT use the full screen menu choice.

Ok I'll check that out later thanks. I've just redone my screenshots (and checked dates - all correct). I couldn't get rid of the pie chart but I think all the info and 4 preferred graphs are clearly visible. The link should be the same as before, but just incase:

Hopefully this will shed a bit more light, going to bed shortly and can't decide whether to switch to FF Mask. I haven't had a chance to look at the clinical manual yet, but will also consider changing my lower pressure as you suggested.

Ok, have put this on imgur as requested:

APAP Data 20-26 Feb 2017 https://imgur. ... lery/XV1G3

The bulk of your large leak flagging is occurring when the pressure is substantially higher than when you start out the night.
Those may not be mouth breathing leaks...they might just be loss of seal due to pressure increasing beyond where your initially fitting for seal can handle.

I still say next step is narrow the range by increasing the minimum and then reseating/fitting at the new minimum which is going to be closer to those higher pressures and the mask should stay put better.
As to what new minimum....probably 7 or 8 since that is where the median seems to want to be.
With a more optimal minimum the pressure may not climb quite as high anyway. Might kill 2 birds with one stone.

Agree with Pugsy. You need to raise the minimum. You can see that when you have events it increases several cm prettly quickly several times. By increasing the minimum you will give the pressure a more steady line and help your leaks. I would go with 8 cm.
For your screen shot we need one more thing. The pie chart doesn't really give us any helpful information and hides some that is helpful. So go to File - Preferences - Appearance, then uncheck Show Event Breakdown Pie Chart.

I can see what I need to see even with the pie chart stuck in the middle on these last images.
The last thing in the statistics column that I really want to see is % of time over the red line.
As long as I can see the total AHI and the breakdown of that AHI in each bar graph and the statistics then I am good when the statistics end with the % of time over red line statistic.
Number of sessions is going to be off screen if the pie chart is shown but most of the time the number of sessions isn't that useful.

I mention this because I personally have had times where I couldn't seem to turn off the pie chart in SH.
Removing the check mark didn't/wouldn't stick.

Thank you both, I will look at raising the minimum tonight, I also need to try the resolution trick in SH before I can hide the pie. I feel I'm almost there but not quite with my therapy so hopefully this tweak and mask check will help.

Ok, making some progress now!
I have managed to get SH out of full screen mode and have hidden the pie chart.
Also managed to change my lower pressure to 7.4 so we'll see.

Last night I changed a couple of things with my mask management, I tweaked the straps just very slightly tighter and re-routed my hose so that it was coming over the top of the headboard and possibly tugging less.

Just looked at last night's data and the leak rate looks to me like it has gone right down. Please could you have a look and see if you agree? Sorry it's on Google drive but Imgur seems to be down atm.

please don't use google drive.

Your leaks do look better. You only had that one large leak at the end of the night when your pressure increased. Looking forward to see what the minimum pressure increase looks like and hope with the leaks controlled and the pressure increased smoothed out a little you get better sleep.
