Leak rate (SleepyHead vs SleepMapper.com)

[CavemanSean]

Today I decided to try out this SleepyHead software I've been hearing so much about on the forums, and I'm seeing something that doesn't quite make sense to me;

According to the chart on a website called SleepMapper.com I'm having no leaks what so ever, I even feel around the mask before going to bed to ensure it has a seal, I tend to wake up during the middle of the night due to gas/bloating (which from what I read as I get useto the cpap will hopefully subside) and I never feel any leaks what so ever

Below is a screenshot from SleepMapper.com

I was informed "Mask Fit" means leaks on sleepmapper

Below is a screenshot from SleepyHead


So how is it, that both places pulling data from the same thing can show two different results?
I have done some digging around the forum on how to read the "leaks" and "total leaks" and from my understanding leaks are actual leaks and total leaks take into consideration me breathing out and the air being vented out of the mask, is this correct?

Fixed images, for some reason my server decided not to like the pics

Can't see your images yet. Can you try again to get them to show up. Use the preview button to test your procedure.
So I can't answer the question about the different appearance of the leaks.

I went to Sleepmapper site and I can't use it yet. It apparently is not set up for BiPaps yet.
So I am unable to compare my SleepyHead results or my Encore results with whatever Sleepmapper is doing.

There we go

I don't know why but my server decided to disable remote linking to them, all fixed.

Are you using ramp? That would explain the short time when that top leak line gradually increases...lower pressure thus lower vent rate. Vent rate will increase as pressure increases.

I don't know what they are using for 100% unless they are wanting to say Mask fit was 100 % and no large leaks were present.
Your SleepyHead total leak (top line) would be what Encore software would show in the default setting for total leak.
So SleepyHead matches Encore.

I can't get into the other stuff to check the wording and what each thing means.

Is that one image all you get as far as a report on how things are going?

[Pugsy]

Respironics doesn't get all worried about leaks unless they register as large leaks. That's why we only get a % of time in large leak showing on the machine's LCD screen.
I am thinking that is all this website thing is going to look at. I don't think they are going to give the in depth detail that the full software gives.
So I think that what it is reporting is that for 100% of the time you didn't have any large leaks.

[CavemanSean]

Ahhh that would make sense then;
hmmm here's some more pictures of SleepMapper.com


Login screen


What you see when you click "Therapy"


What you see when you place mouse over a "Therapy" event


What you see when you click "Mask Fit"


What you see when you place mouse over a "Mask Fit" event


What you see when you click "AHI"


What you see when you place mouse over a "AHI" event

Although I know the date is off, can't seem to figure out how to fix that


As for if I'm using RAMP, I am for the 1st month using it.
I did notice though on days where they had set me on a constant pressure without the ramp my AHI jumps up...

So far though I'm loving SleepyHead way more as it gives more info, but I'm just curious as to why both places pulling data from the same location can have such different results...

[Pugsy]

Pretty boring stuff compared to SleepyHead or even their own Encore software.
Goes along with what they think is sufficient for a patient to see (like on the LCD screen). General AHI, as long as no large leak is registered everything is hunky dory and hours used. Focusing on trends and long term stuff.

What are you seeing that might be off compared to SleepyHead or Encore?

[CavemanSean]

AHI's the main one I'm seeing for the most part its correct

but on the high day (Tuesday.. which was actually Wednesday) it reports a AHI of 3.2 SleepyHead reports the AHI at 2.8

The other days are fairly close;
2.9 on Thursday on SleepMapper
2.87 on Thursday on Sleepyhead

0.4 on Friday on SleepMapper (now that was an amazing nights sleep! lol)
0.43 on Friday on Sleepyhead

1.3 on Saturday on SleepMapper
1.31 on Saturday on Sleepyhead

but I can't figure out why Tuesday has such a huge difference... sure its minimal but I'd still like to know what software to believe...

I'm also hearing alot about this Encore software, is there anywhere I could find a trial version..
Time to do some digging online to find more out & hopefully a "vs" thread!

Also Thanks for the quick reply Pugsy!! its greatly appreciated

[Pugsy]

Give me a minute and I will send you a private message with some Encore information.

The minor differences in AHI are just a rounding thing. Encore and Respironics only goes to the tenth. SleepyHead goes to the second decimal point. Rounding up or down is what Respironics will do to only the first decimal or tenth.

Unsure about the difference in the one date that is more than a rounding difference.
SleepyHead is Beta software but I never found any huge differences between it and Encore.

"The answer to your Question is most likely this..... There is a Calibrated amount of leak on Any mask. You can get the exact amount of acceptable leak from the Mask Package insert. The Respironics Machine is taking that into account when it reports the Leak as good, or bad. Sleep mapper is looking at the Actual leak, and not taking into account what is acceptable from the mask or not. It is giving you the real time number."
Hope this helps
