Having Trouble With Oscar

[Deborah K.]

On occasional days recently I get strange Oscar readings.  the right charts show nothing for many hours.  I'll attach a couple for you to see.  Does anyone know why this happens sometimes, and what I can do to stop it?

Unless you really are sleeping from 11 AM to 8 PM... my guess would be your CPAP clock is off by 12 hours, or close to that.

If you can set the clock forward to fix it, you won't have any problems. If you have to set it backwards, you should wait until late afternoon and set it back no further than 13:00 each day. It may take several days to get it right.

I fixed my AS11 by changing the time but it deletes all of your data in doing so. You'll have to reconnect it maybe.

The AS10 has a setting to adjust the time. The AS11 does not, making it more difficult to adjust the timezone.

Deborah, your charts show a lot of high leaks. Are you still using a Bleep mask? You had leak problems in the past http://www.apneaboard.com/forums/Thread-...lease-Help Is this also a connection problem with the Bleep? Your older thread did not show this issue. Perhaps you should consider a different mask?

As far as date and time, you had this thread in November http://www.apneaboard.com/forums/Thread-...te-problem Were you ever able to resolve the date and time?

[Deborah K.]

Sleeprider, yes I was able to set the date and time. The problem now is the gap in reporting on some days, but not most. I guess I just won't worry about that for now.

The other issue is the high leaks. I actually showed the high leaks with my Dreamstation, but that machine listed 0 large leaks on the data on the left, so I didn't worry about it. The Resmed reports the leaks better. I am experimenting with using mouth tape. Last night I used some and got much lower leaks. I'm doing further experimenting, so hopefully I'll do better on all of this.

Does the time set in the CPAP machine match the time on your computer?

I have had an S9E and an S10 *for her*, both are ResMed

On my machines I need to wait until after noon to change the time on the machine.  If I change the time before noon in my time zone I lose my data. If I wait (even longer--early evening? I don't lose the data.

Hope this helps.

The AS11 has a totally new scheme on its time setting. It will only allow timezone settings and not actual time, and that is only if you wipe out the SD card. Also, there isn't any provision for 1/2 hour timezones in the world either.

The AS11...  will only allow timezone settings and not actual time, and that is only if you wipe out the SD card.

Minor correction -- changing the Time Zone on the AS11 (at least when I did it) does not wipe out everything on the SD card.

It *does* wipe out all the data stored "in the machine's internal memory."  Internal memory holds up to 365 days of "summary" (compliance) data, according to the AS11 clinician manual.  That data must be deleted before the TZ can be changed.

The machine also *does* overwrite the "summary data" on SD with what is in its internal memory.  That means the previous "summary data" stored on the SD is wiped, too.  This happens even if the SD card is not in the machine when the TZ is changed; i.e., the next time the SD is inserted, the summary data on the SD is replaced with a copy of the machine's internal summary data.

But it does *not* delete the detailed session files from the SD card.  At least they weren't deleted when I changed the time zone -- the session files were all still there on my card.  (YMMV.  Firmware can be updated "over the air" and change its behavior at any time, so I recommend having a backup of the SD card.)

OSCAR can still load and use those session files created prior to the TZ change, so there seems to be little (if any?) impact on OSCAR.  It might very well lose some settings data if the SD hasn't been previously imported before making the TZ change.

There seems to be a greater impact on ResScan -- and that could be important to someone relying on ResScan for compliance reporting.  Though for most people using an AS11, compliance data is reported over cellular and handled by MyAir/AirView, so no impact if that's the case.  ResScan can still see, import, and display the detail sessions recorded prior to the TZ change.  But it states "no summary data" is available for those sessions, and I could not get it to provide any statistics, nor any compliance reporting, for any of those days.
