Here we go again. I did download Res Scan, but I'm not sure I know what I'm doing in it yet. Couldn't handle reading all the instructions, so just jumped in.

Last night my Sleepyhead showed an AHI OF 5.55. Res Scan and my machine show 10.3. But for the first time Sleepyhead shows me a detail page that is totally blank. No graphs shown. No events listed other than session start and end times.

ResScan shows the summary graphs page, but on the detailed graphs page just says, "No detailed data available." That's not just for last night, but for the entire time since I started the SD disk in June. What information should I be getting on this detailed graphs page?

Looking back over the previous dates that I had discrepancies, ResScan agrees with the figure shown on the display on my machine, not with the Sleepyhead totals for AHI.

So what's going on? If it is a Sleepyhead problem, why just me?

It has been awhile since I checked my data. ResScan has two options for downloading the data. You have to pick the one that selects all the detailed data.

Well, I just checked the download screen in ResScan again and this is what it shows. I selected the button on the device line. Shouldn't that have given me the complete download? But when I look at the "notes" section, it just lists "received summary data for" all the various dates.

Okay, I just tried to download the SD to ResScan again and overwrite. But when I finished, I got a screen that said Summary data (download complete), Detailed data (not marked for download). So there must be some place else I have to select "detailed," but I can't find it. Grrrrrrr, I hate computers.

You see where it says "Data Summary data only"? Click on the Select button to the right, then specify that you want detailed data. ResScan will remember that for the future. Then re-import your card.

Make it look like this:

So to get detailed information downloaded one needs to click on data summary data only. What bright individual came up with those instructions, I wonder.

Following those brilliant instructions on ResScan, I was able to download some of my detailed data. Not much, though. I got a "download not responding" message after a bit four times and gave up. I think the detailed information got downloaded from the 10th of August until last night, so about a week.

I sure don't like how ResScan presents their graphs as well as Sleepyhead, but if SH continues to give me troubles, at least I may have a little more information than on the machine display alone.

You're welcome to zip up your *entire* sd card and upload it to https://www.dropbox.com/request/0LalWvEsijRIgX8sdM7H
and I'll take a look at it, see if it matches what you have.

What a generous offer! Thanks so much, PR. I don't know how to do the zip file thing, but I'll have my BF show me later. Later today, if he has the time.

Just to repeat the PM I sent you... the data on your SD card is somewhat corrupted, in a way that SH can't compensate for, For instance, the Mask Pressure trace occasionally goes completely berserk, showing recorded pressures of 600+cm/h2o, of course, the machine can't do that, it'd have popped you like a balloon if it could... (assuming the mask kept a seal, which, I'm sure it wouldn't )

There's a lot of event flags that SH isn't picking up, but the apneas are clearly there when examining the waveform. Counting those up, matches pretty closely with the dates you gave me numbers from the machine.

Also, the places where SH says your Respiration rate (don't know if you looked at that) is 50.... it's actually around 16, but cardiac effects are causing your breath to hover back and forth over the 0 line, and SH is counting each heartbeat as a breath.

I'll reformat the disk and start all over. After all the hassles, it will feel refreshing to start over.

I never saw any pressures of 600 on my reports, did I do see that on my Sleepyhead statistics it showed max pressure at 24.52, and I know my machine doesn't go that high, so I knew something was amiss there.

When I finally was able to get some of the detailed disk information into ResScan, it showed the totals AHI the same as the machine said. It could apparently read that part of the disk whereas Sleepyhead couldn't. But the more detailed information was hit or miss. One day it read it and another it didn't. And last night was crazy. It uploaded to Sleepyhead just fine and the AHI matched the machine dial. But last night's session wouldn't upload to ResScan at all. Yep, reformat and start over.

Yes, I did look at that respiration chart and noted several times over the weeks that it couldn't possibly be right. I considered asking about it on the board, but since I've had more important things about this CPAP to figure out, decided it was low priority at that point. Interesting that the cardiac effects are influencing the way SH interprets it.

Thanks for all your help, PR. I'd be totally lost without the help of the good people on this board.

Have you tried a different card? Maybe the card has defective spots on it, so it can't write the data correctly.

You'll have to zoom in, but look at the number on the mask pressure graph.

Wild! No, I never zoomed in and saw all those variations in the level. I just saw the line that went to the top of my graph and assumed it was like a previous line up and down a graph that I'd asked about which you said was probably just a glitch in the Sleepyhead software, so I didn't explore it any further.

So much to see in those Sleepyhead graphs! I'm having a hard time interpreting the wave forms on the flow rate charts, but feel I need to try to do a bit more studying of it all before I bother you good folks with more questions about it. But you'll likely be hearing from me about it eventually.

I'd say that trying to get a sense of what's going on by looking at the breath shapes is one of the more involved things, much more detail than looking at the pressure curves, or leaks

Saw this in one of Pugsy's posts and immediately saved it to my computer. It's helpful. There's much more to interpreting a chart, but this is handy.

Thanks for that chart, djams. I'd seen the chart before, but the words identifying the difference between the lines on the chart weren't clear enough to read, so it wasn't of much help. I can read this one. Interesting in comparing what I see here to some of my breathing patterns last night.
