Question about synchronizing time in A10/ Sleepyhead/Rescan

Post by MarylandCPAPer » Mon Aug 03, 2015 8:17 pm

When does the day (date) start on an A10 machine? When in Sleepyhead? And when in Rescan 5.4.1?

The date is off by at least a day on either or both of my A10 and the Sleepyhead and Rescan 5.4.1. software. I never go to sleep before midnight, so any sleep data SHOULD be on the date of the actual day (starting at midnight). Unfortunately, I did not use any software until a few weeks ago and i have never been able to see the current day's data (for a sleep range such as 3 am to 2 pm). Or, at least it does not seem that way.

Can anyone with experience with Sleepyhead and/or Rescan 5.4.1 and/or the A10 give me any guidance on the time issue? If it makes a difference, I am using Sleepyhead and Rescan on a desktop computer with Windows 8.1, not a cell phone or any other device.

I know that the time on the A10 starts a new day at noon, but my preference would be for a new day on the A10 and in the software to start at midnight and extend to 11:59 pm.

Thank you for your help.

One way to deal with it is to set your machine 12 hours ahead, so it thinks you're going to bed at 3 pm rather than 3 am. When you get up at 2pm the machine will think it is 2 AM and you will be able to see the current day(the sleep you just had) on it.

Maybe better would be to set the machine back a few hours so that it thinks your going to bed around 9 pm rather 1 am, that way when you get up at 1pm the machine will think it's 9AM and again you would be able to see your last sleep on it.

The software in both cases would report the times according to the machine setting

In my opinion, since the software will sort it out properly, I would leave everything on the right time. To me it would make more sense. The only thing you can't do is look at the machine and see the Last night data if you sleep past noon. But, if you take the card out and read it with Sleepyhead or ResScan, it will be there.

I know of no way to change the day start on the machine.

you can change the split time in the 098-1 SH version, and it'll attempt to glue things together so they look right, I had it at 6pm for a couple friends that were staying up late and sleeping till midafternoon on a regular basis

Right, I forgot about that in SH, but does it really make any difference? When I just went out west I left my machine on Eastern Time. So every night I went to bed after midnight according to the machine. Oh, but I did get up before noon in any time zone so I was always OK there. Yeah, good point. But read the tool tip, Mary.

The split time is under preferences.

the main thing was when viewing their data, I'd see 2 hours from noon to 2, for example, from last "nights" data, then 6 hours from 6am to noon... with a big blank area in between... by changing the split time to 6, I can see the whole 6am-2pm in one chunk. it's a bit of an approximation because of the way the machine splits at noon, but for those that aren't terribly OCD about things, it's good enough and makes the charts look a bit better

I put the SD card in after midnight 8/4 and got graphs that show perfectly the sleep statistics for Aug. 4, although I have to click on August 3 on the calendar to see them.

I also set up "My Air" yesterday and let it get the statistics by turning off Airplane mode.

I have another question. I forgot to turn the lock on the SD card to on. Am I going to have a problem when I put the SD card back in the machine tonight?

Time goes from noon to noon. So, even if you go to bed after midnight, the session for noon Aug3 to noon Aug 4 will be dated Aug 3.

The solution is to change the time on the machine so that you get what you want. I set mine so that "noon" happens at 3pm. (or 4pm part of the year). While I don't go to bed before midnight, I don't care that it has last night's date. I only care that my sleep sessions are together and not split.

Who would have thought it would be this challenging to sleep and breathe at the same time?

Right, the machine sees that as the "night" of Aug 3. Which, if you think about it, is they way we often think about it, too - as in, "I didn't go to bed until 2 o'clock last night". If you'd gone to bed before midnight, you would have expected to see the bits before and after midnight displayed under Aug 3, correct? In your case, there just isn't any sleep before midnight. The night of Aug 3 is considered to be anything after noon on Aug 3 until noon on Aug 4.

The only time, I think, this might be a problem is if one routinely sleeps past noon. Then, I think, as I and Zoo have suggested, you might want to set the time of the machine to accommodate your schedule. E.i., so that the time of your rising is before noon (on the machine). Or, just don't sleep past real noon

Note: Caution is required when setting to a past date or time. Generally speaking, you can not turn back the date without losing all stored therapy/compliance data. See the manual for more details.

Depends on your software and computer. Some write a little something to the card which will cause the ResMed device to reformat it and you will loose the detailed data stored on the card. No big deal, if you've already downloaded it to ResScan and SleepyHead. The machine will retain and rewrite the compliance (summary) data. If something has been written to it, when you reinsert the card into the machine it will ask something like "Erase the card" yes or no. The natural tendency is to say no, but you have to pick yes to proceed.

It seems that Sleepyhead and the A10 are synchronized on time. It is the Rescan 5.4.1 software that I have to wait until after midnight to download, even if I am not going to sleep any more before midnight. It is the program asking if I want to overwrite or discard changes to the data when I try downloading it before midnight to see the current day's sleep data. I have "discarded" it.

Fortunately, the A10 did not give me any error codes when I put the SD card back in last night, so evidently no strange files were written on the SD card by my computer. Last time is the only time I have put it in the computer in "unlocked" mode.

That's just a little quirk of ResScan. It comes up whenever you're loading new data and there is existing data on the card that has already been downloaded. I don't think it has anything to do with sleep times or the time of downloading. I always choose "overwrite" as it seems to be the default. I've read differing arguments for choosing one or the other, but I don't think it makes any difference. The data on the card is what has been downloaded so it could be overwritten with the same data or discarded and the data is already there, so...
