Sleephead question

[newname]

Yesterday I was able to down load Aug 16 info. Today it doesn't work. When I insert the card, I have to download Sleepyhead again and go through all the steps to install again. And I still don't get the data I'm looking for. Is it possible the data didn't get recorded to the SD card?
What am I doing wrong?

Ignoring SleepyHead for the moment, check whether your card is valid and properly mounted on the computer. If it is, you should be able to list files on it with e.g. Windows Explorer. What to do next depends on the result of that test.

Have no idea what you are doing but please read the User Guide.
http://sourceforge.net/apps/mediawiki/s ... sers_Guide
Once you navigate to the drive letter where the SD card sits SH should ask you "do you want to remember" tell it yes and the next time you try to download you should get a prompt "the usual" as one of the choices. Choose "the usual".

It sounds like you aren't going to the correct file path for the SD card. If you are going to a folder you have gone too far. You shouldn't have to keep installing SleepyHead. You are doing something wrong but unless I was watching you I have no idea what you are doing....if you could list exactly what steps your are doing...we might be able to offer an idea.

The most common error made when using SleepyHead is that people go to far into the SD card and look for the first folder. Since SleepyHead works on multiple machines you can't ask it to look in a folder because it doesn't know to look in a single folder....instead it looks in the drive where the SD cards. If you try to tell it to look anywhere else it gets confused.

Guilty as charged... I did that the first time I used it. Once I got it working correctly, I've had zero problems with SH. One of the best freeware programs I've ever seen, and I've tried and still use a bunch of them!

Back to the original newname post, I am wondering why you had to reinstall Sleepyhead? I can't see how you have lost it by simply using the program ok the previous day. There seem to be strange issues here, so a few questions to answer please.
1). Was Aug 16 the first time you have used Sleepyhead? If it isn't, please advise the size in Mb of the folder called SleepyHeadData in your My Documents folder....hover the mouse over it and it should tell you some details. Regardless, copy and paste this entire folder somewhere else for now as an immediate backup....but it might already be too late!
2). When you put the SD card into the puter, does anything automatically run....or try to?

The main stumbling block for me is that you lost the program! Perhaps in doing that and then reinstalling you have somehow upset the path to the data on the card and also perhaps overwritten all your previous data on your puter if you had any.

Cheers,

Nods

I get a pop up box that says "open folder to view files" when I insert sd card. I click on that and get a list of things I don't understand. Should I just delete Sleephead and just read the daily info on my machine?

OK, that means your computer can read the card. Since it was able to read your files one day, you must have one of the machines it knows about.

Now try again using SleepyHead. When you do the import, specify a new location, and remember you need to specify the card itself, not the top folder within the card. If you are on an MS-Windows computer, the folder you want will be a drive letter. After doing that, if it does not work make notes of exactly what does happen, and post them here.

Ignore that box...X out of it to close it. You won't be using that box or its choices at all.
I get the very same box every time I insert the SD card. If I was using a CD or DVD disc..the same box pops up. This box is used for other functions that are not needed to use SleepyHead. You can totally ignore it.

Go open SleepyHead and then import the data.

It is important in this case because it means the card does contain data, is correctly connected to the computer, and the computer can read it. Computer debug is very much about considering a wide range of hypotheses about what is going wrong, and eliminating them based on evidence. Unreadable card needed to be considered, but has now been eliminated.

Yes, I know. I was just trying to keep things simple for newname. I get a sense that experience with this sort of thing is limited for her.

[Noddyman]

So...... as the others have said the card appears to be working ok.

What was the answer to my first question? This is also important as to where we go from here.

(by the way, Pugsy, I'm still having timeout issues!)

What does this show? What does Sleep 21:08 mean? WAke 05:04? Hours 03:55:13? My machine says I slept almost 4 hours. What is this sleep and wake mean?

Sleep is when you first turned the machine on. The assumption is that's the time you went to bed. And SleepyHead uses a 24-hour clock. So you first turned the machine on at 9:08 PM. Now--you may not have gone to bed that early---you might have briefly turned the machine on for some reason---testing things out as it were.

Wake is the time you turn thre machine off for good in the morning. The assumption is that you will only turn the machine off for good when you wake up for the morning. Wake = 5:04 means you turned the machine off for good at 5:04 AM.

Hours is the total time the machine was ON during the night. You used the machine for 3 hours, 55 minutes, and 13 seconds between 9:08 PM and 5:04 AM.

Now if these numbers make no sense, it could be that the DME either did not set the clock at all or set it incorrectly. You neecd to get into the clinical menu to check and to set the clock.

AHIApnea / Hypopnea Index 0.51
HypopneaHypopnea 0.00
ApneaUnspecified Apnea 0.00
ObstructiveObstructive Apnea 0.51
Clear AirwayClear Airway Apnea 0.00

You are right: The machine detected no hypopneas, no "unspecified" apneas, and no central apneas. An "unspecified apnea" is scored when the results of the S9's FOT algorithm are so ambiguous that the machine cannot decide whether the apnea is an OA or a CA.

The the AHI is the average number of events per hour. The machine computes AHI as follows:

• AHI = (number of events)/(time the macine was running in hours)

.
Since you used the machine for 3:55:13, you used the machine for 3.92 hours. We can figure out number of events as follows:

• 0.51 = (number of events)/3.92
  so
  0.51 * 3.92 = number of events
  so
  number of events = 2

In other words, the machine recorded 2 OAs during the entire night (since there were no Hs or CAs).

Note all the numbers in the colored table in SleepyHead are indices: The "Obstructive Apnea 0.51" line means that the OAI = 0.51. That's another way I know youe had 2 OAs during the night.

The session information is kind of interesting.

The machine was on for one hour and 9 minutes, then off for almost 2 hours. Ran 50 minutes and then was off for 1.75 hours....

Did you intentionally turn the machine on and off many times?
