Odd data problem on Respironics System One INFO screen

I have had my Philips Respironics System One for just over 3 months. I've used it every single night since I brought the unit home from my DME provider, Apria Healthcare. I have 100% compliance with an average of between 6 to 7 hours per night.

Upon waking up every morning, I check the LCD INFO screen on the unit to see the number of hours of therapy I received, my AHI and the pressure delivered (my machine is set for Auto).

Just about 2 weeks ago I started to experience an intermittent issue wherein all the data pertaining to that night's CPAP use is 0.00. It's happened roughly 4 times in the last 2 weeks and neither Apria or my insurance provider can figure out why data is not being reflected in the INFO screen for those particular nights. And though the info is not reflected on the System One screen, my insurance provider has told me that data is indeed being transmitted. In fact, the respiratory therapist for the insurance company thinks that the time at which transmission of data takes place seems to have been changed to the early morning hours (between 5 AM and 7 AM) which she believes is resetting the unit's INFO screen. Apria has given me no useful information and no resolution to the issue.

Do you think that my insurance company is correct that the actual transmission of data is somehow zeroing out the data that I'm able to see on the System One INFO screen, or, is there a problem with the CPAP machine itself?

At this point I'm not sure how to pursue this issue as Apria has been quite useless in trying to diagnose and fix the issue. Any pointers you might have would be very much appreciated.

Have you tried Sleepyhead? It would be interesting to check with that.

You might try unplugging the machine and plugging it back in if you haven't done so already. I had an S9 that did something similar, unplugging and plugging it in resolved the issue.

Thank you both for the suggestions.

I have just registered for sleepmapper.com but Apria Healthcare needs to enable it for me.

I have also tried unplugging and re-plugging in the unit to no avail. Some nights it reports accurate data on the INFO screen and some nights it reports 0.00.

Sometimes I will see what appears to be missing data if a patient goes to sleep after midnight. It makes it appear as though they missed a night of use.
I am not sure if this is what is happening to you or not.
I think the software one of the other members mentioned does not require Apria to do anything.

I don't know the answer but I wonder if you get up in the early morning to go to the loo and shut off the machine --does that screw up the info screen . Or if you accidentally start the machine in the morning for a few seconds does that also mess the info screen up? I know sleepyhead tells me the truth about the total hours per night and counts restart as another session . But I suspect the info screen in very fallible and just counts hours from the last start.
Always too sleepy to run a test on this.

Which PR System One machine are you using? Model number off the bottom of the blower unit????

Respironics machines are all set to correspond with GMT time and the LCD screen data won't update until after 12 PM GMT time.
Is it possible that you are trying to view the LCD data for last night prior to 12 PM GMT time?

So where ever you live...calculate GMT time hours difference and figure out what time your machine thinks it is...and that is when the machine will update any data on the LCD screen.
On the SD card...doesn't matter...the files are written to the SD card until the machine is turned off and final session close out data is written.

What shows 0? Everything? AHI? Hours of use? Leaks? Can you be more specific?

I vaguely recall there is a setting in the clinical menu that shuts off patient access to see data? Perhaps that's been turned on and is zeroing out everything?

No, it won't zero things out if that "show data" feature is turned off...it just won't offer anything at all. No AHI or leak or whatever will even be offered.
OP says sometimes he sees last night's data (whatever he is seeing) and sometimes he doesn't....so it works sometimes and not others. Unless someone was turning the view data thing on and off intermittently that feature on the machine is not causing the random times where whatever he is viewing is set to 0.0.

I am thinking OP has a 60 series machine that shows single night data along with the normal 7/30 day data since he specifically mentions "last night's data".
If so then the prime suspect would be GMT time 12 PM...and perhaps where he lives and is trying to view the data the machine thinks noon hasn't happened yet. Doesn't really matter what he is wanting to view...the machine won't show it until 12 PM GMT time has passed when looking at a single night's data.
Also side note...the 7/30 day average numbers won't be updated until the 12 noon GMT time has passed.

Here are some additional facts, in answer to some of the questions posted:

- This only seems to happen when I do shut the machine to use the bathroom/loo between the hours of about 5:00 AM and 7:00 AM EDT, and then restart it when I return to bed (a duration of approximately 3 to 5 minutes).
- Until about 2 weeks ago, the PR System One ALWAYS appended data to the INFO screen once I returned to bed and turned on the machine back on.
- The data that is zeroed in those intermittent situations is: Therapy hours (1 day); AHI (1 day); 90% Pressure (1 day). Cumulative data is not affected.
- Downloaded SleepyHead and all data, regardless of what the unit's INFO screen reads, is recorded accurately. (Imported data to SleepyHead using the unit's SD card.)
- The model is the PR SYSTEM ONE REMSTAR AUTO 560.

When are you checking the onscreen data? At the 5 to 7 AM break in therapy for the bathroom break? At final wakeup?
What is the time zone where you live?
I am betting the missing data is only missing short term because of the Noon GMT time thing for on screen updating.

I checked onscreen data both before the bathroom break and at final wakeup. Prior to the bathroom break the onscreen data was up-to-date for that night's sleep. After checking at final wakeup, the data for the night was 0.00.

I am in the US Eastern Time Zone - EDT.

I have a 560 and if you shut the machine off like that in the AM for more than a certain number of minutes, then it will reset itself to zero. It thinks you are sleeping for the next day (best I can describe it.) It is only after a set number of minutes, but I am surprised yours is doing it only after 5 or so. That is too short a time because people do get up to use the toilet for more than a few minutes.

Does anyone know the exact cut off time?

I have just tucked my mask under my pillow for a quick BRB. I don't have to disturb Hubby turning the oxygen and the cap back on.

Eastern time zone is 5 hours behind GMT time...and that's standard time without DST figured in.

I suspect that sometimes you are right on the cut off time for the machine to think you are starting a new day and that's why the 0.0 numbers until the next Noon rolls around and the LCD onscreen data gets updated again.
If you turn the machine off...after 12 PM GMT time then the machine will start a new day and the LCD data for the past night won't reflect the recent short session until it gets included with the nightly data.
The software calculates off the SD card data files...the machine does something different.

I don't think anything is wrong with the machine. I think sometimes you are just past the 12 PM GMT time when you start and end a brief session early in the AM due to bathroom break.
