0.00 AHI but graphs look weird - jolycu - 11-29-2015

This is my husband's data from last night with a 0.00 AHI :grin: but the graphs look weird, especially the ones in the second picture. Tell me what you think.

Assuming that SleepyHead is the issue, you can try rebuilding the data.

You can try purging the data for that day, same menu: Data > Advanced > Purge Current Selected Day and importing it again in case the first import didn't complete.

You can also try to reset the graphs. The Respiratory Rate graph looks narrow. Right click the numbers on the left of the graph and choose reset graph layout. You can also check the Y-axis is set to Auto-fit scaling mode.

Thanks for your suggestions AlanE. I did all you suggested and it still looks the same. It just looks like there wasn't much data recorded in the second pic. Maybe that is normal for a night with a 0.00 AHI?

No, not normal -- a 0.0 night should still have all the graphs. Thinking-about

Could be a display issue with your computer.

RE: 0.00 AHI but graphs look weird - jolycu - 11-29-2015

Thanks everyone for your responses. Kaiasgram, I also thought there should be more information shown in the graphs. Nelamvr6, I don't think it's a display issue because other days are displayed just fine.

He had a similar night back on the 9th of Nov. Screenshots below.

It would be nice to believe that these are accurate results but I'm afraid they're not.

RE: 0.00 AHI but graphs look weird - nelamvr6 - 11-29-2015

I have had issues with my data being corrupted in SleepyHead before. What does the report on your husband's machine say his AHI was last night? That should be accurate.

RE: 0.00 AHI but graphs look weird - AlanE - 11-29-2015

I'm not an expert on your machine, does it have an SD card? How old is the machine and is the card original? Have you tried another card?

RE: 0.00 AHI but graphs look weird - jolycu - 11-29-2015

Nelamvr6, the machine reports an AHI of 38.3 last night! Huh

My husband said he had a very restless night last night for some reason and thought he had even taken the mask off for awhile although it doesn't show up in the Sleephead data. Is there a Respironics software that I can use for comparison with Sleephead?, If so, do you know where it could be downloaded?

AlanE, the machine is a little over a year old and as far as I know, it's the original SD card. The machine belonged previously to my sister. If I were to get a new SD card, is there a way I could clone the data on this card to the new card so it's not lost? My husband is a truck driver and will have to furnish this data at his DOT physical in January. He has to have a full 90 days of data or they won't pass him for his physical, so we definitely don't want to lose any of the compliance data!

The machine store compliance data and write it on the SD card. If you stick a brand new card in the machine, the machine write compliance data on the card. The only time compliance data is lost, if you erase the data on the machine, (run hours cannot be erased) which should be done when your husband first used the machine and to delete the data of the previous user
EncoreBasic software support the machine too but windows only
