Strange Pressure reading - apneaeric - 04-06-2022
[attachment=41413]
My Airsense 10 Autoset data showed this strange "Pressure" report this morning--a straight line decline over 2 1/2 hours from 5.00 to zero, starting when I turned the machine back on after a bathroom pause at 4am. (See attachment.)
The "Mask Pressure" graph doesn't show any change over the course of the night.
Any ideas what this means?
Thanks

It's a data reporting error.

This is an artifact of the 'smoothing' algorithm used by OSCAR. To eliminate it, you can click on 'Square Wave Plots' in the Appearances tab of Preferences. It will be fixed in the next release of OSCAR.

To me that looks like the last data time it got was at 4am then it knew the pressure was at 0 at at 6:40 when you woke up and it forgot to collect data in between those two times, and the program guestimates what the values are between two data points and so if it had a data point at 4am of 5 and then no data till 6:40am at 0 it would draw a straight line from 5 to 0 over that time. Kind of surprised it did a straight line as a pose to an exponentially declining line but still point is it looks like maybe there was an issue with the data being written like maybe it was in the middle of writing data when you turned it off causing that portion of the data to become corrupted when you turned it back on.
Nothing to really worry about unless it keeps happening multiple times, but yeah that just looks like it just had no data to fill in and so went "well it is at 5 at 4am and 0 at 6:40 with no points in between so lets estimate that line only having two data points to guess what the line looked like.
