AirSense 10 - stopped transmitting data and (maybe) turning itself off?

[indeeditis]

Hi, everyone!

After ten years struggling with always being tired and multiple problems that arose from not getting good sleep, I've been using a ResMed AirSense 10 for about seven months now and it's been a game-changer. I was off to a rough start with the P10 mask they gave me, but after lurking around in the forum I was able to find a mask that was a good fit for me (AirFit F20), find the right settings for my therapy (8-20, with auto ramp, full time EPR at 3) and even tame aerophagia (although it still happens sometimes). So, first of all, thanks for all the amazing content and help you guys have been putting together here.

The reason I am posting is that I've started having some problems with my machine in the last few days, as follows:

1) It stopped syncing to MyAir. That's not really a problem as I check my data with OSCAR once or twice a week, but still, I've tried power-cycling it like some people recommend and it didn't come back to normal (last sync was on November 3rd). And, I don't know, it might be relevant in the context I am going to explain.

2) I've also noticed that the numbers are usually a little off between the sleep report screen and OSCAR. Not by much, but my machine always shows 0l/leak while OSCAR shows a ~2l average and also the AHI is a little different. Not sure if this a problem or not.

3) Anyways, this is the big one. For the last two days, my machine has shown ~5h of usage time and not the full hours I've slept.

I am currently trying to diagnose and overcome a bladder problem, and that's making me wake up quite a few times at night to pee (up to 4-5x) so, the first night it happened I just shrugged it off to maybe having fallen back asleep without turning it on after a bathroom break.

When it happened again this morning, I decided to go check my data and see if I could make sense of this issue. This are my OSCAR stats for the last two nights:




(I don't know why, but since I updated OSCAR it's showing everything one hour earlier).

The thing is both days show that the period the machine was off was quite early in the night, when I had just gone to sleep and (iirc and the data from my smartband is to be trusted) hadn't woken up not even once. So, all these things combined, do you guys think my machine may be malfunctioning or is it something else?

I've also uploaded the data from three nights before in case it helps making sense of the problem:

Again, thank you very much for everything and any help is much appreciated!

Check the clock on your machine. Confirm that it reflects your local time...we did have a DST change recently.

When you are looking at your LCD screen data have you gone in and changed the data parameters so it reflects one day and not the default 30 day average? Whenever you did the power cycle trick and unplugged the machine for a period of time and then plugged it back in the machine will default to the 30 day data average of reporting on the LCD screen sleep report.
This might account for the slight difference between what you are seeing on the screen and the daily OSCAR reports.
OSCAR is showing a daily number but the machine might be showing a 30 day average number.

Anytime you lose power the machine reverts back to reporting a 30 day average

Your number 3 issue...again that might be related to the 30 day average thing.

You will need to go into the clinical setup menu area to change the reporting data parameters.

More likely, it's been off an hour since we set out clocks back last week.

Go into clinical mode and set the time on the machine back to standard time.

Hey, guys.

Thanks for the quick response. I am in Brazil and we don't have DST here anymore. I checked the machine's clock and it was off by only three minutes, so I've corrected that. Anyways, the time is wrong when I look at the data on my desktop but not on my laptop, so I am guessing it has something to do with my OSCAR profile settings.

I didn't realize that power-cycling the machine would bring bay the 30 day average as a default. Thanks for that tip. I've changed it back to the 1 day view and it stills shows 0L/leak (whist OSCAR shows 1.67L) and 0.1AHI (whilst OSCAR shows 0.2). Anyways, don't think that's a big deal either.

I am really concerned by that big gap when I am sure I was asleep. I have pretty stable energy and never seen that before. So that, combined with it not sending the data up to the cloud anymore, makes me worry something might be wrong.

Ensure that you computers settings have the correct time, timezone and do not have Daylight Savings checked.

[Pugsy]

There is a time zone selection in your OSCAR profile. Confirm that it is the correct time zone....you can edit your profile and change it.
If you have the wrong time time zone selected the reports will be off.

The machine LCD data shown vs OSCAR details could also simply be a rounding up or down thing.

The machine shows 95% numbers...not median average or max. I don't know which parameter your 1.67 L/min is but that might also explain the slight difference.
But...it doesn't really matter...too small of a difference to worry about and I don't think related to machine potentially ailing.

The gap in usage...I am scratching my head over. It does seem to start at approx the same time each night and end at approx the same time.
I would first simply create a new OSCAR profile and make sure time zone is correct and do another download and see if the gap persists.
You have have more than one profile in OSCAR without issues.
If that doesn't resolve the issue then I might want to confirm with ResMed software...ResScan...but it is Windows only.

It was all setup right, expect for my OSCAR profile. Made a new one and it's all good again. Thanks, Pugsy and Dog Slober.

So here is my data with the clock corrections for the two "problematic" days:

0811.png (129.35 KiB) Viewed 880 times

0711.png (136.34 KiB) Viewed 880 times

As you can see, it turned off around 50 minutes after I went to sleep and only turned back on at around 3am (which would've been getting back from a bathroom break). I do think it's not only a reporting problem, as I woke up today with a headache and feeling just overall crappy.

And here are three "normal" days to act as comparison:

Edit: I was just fiddling with my machine right now and realized I threw my disposable filter away on Friday morning and forgot to put another one in.
Friday -> Saturday stats were normal but Saturday -> Sunday and Sunday -> Monday have that big gap. I wonder if that might have to do anything with it. I've just put another one in and hope that solves it!

I don't know about Brazil. In the US we have machines that stop transmitting because the modem is obsolete. My Resmed Autoset S10 does not transmit. If I look at the setup menu under "about", it says the modem is CDMA, which is being phased out. You said your clock was three minutes off. If the modem were working it would be set every day.

But we don't need the modem if we have a SD card.

I don't think the machine gets the time from the wireless connection ... at least I have seen that said to other people.

After I put the disposable filter back, everything seems to be working as intended. Got seven and a half hours of usage yesterday and seven hours today, which is spot on with my sleep pattern.

As for the syncing problem, I don't think my machine has a CDMA modem as it's a new one, but I talked to my DME and they said there's been widespread complaints about that in the last days, so I am guessing it's possibly a problem with the carrier.

Thank you very much for all the help guys. Doing God's work here!
