AirSense 11 display anomaly

This is weird, and likely not a major problem, but I'm curious as to whether anyone else has experienced the same issue.


Last night, after about an hour and a half of sleep with my ResMed AirSense 11 Auto running, I needed to get up and use the bathroom. I shut the machine off, and it showed 0.0 hours of usage, 0.0 AHI. (I'm sure I had the machine running, for when I hit the power button, it showed the display screen, whereas had it been off, it would have turned on.) Went back to bed, turned the machine on, and slept for about another two and a half hours before I needed another bathroom call. Turned the machine off, and it read 0.4 hours usage, AHI 0.4. Went back to bed, turned the machine on, and slept for about another four hours. Got up, turned it off, and it read 0.6 hours usage, AHI 0.6.


So I pulled the SD card and loaded it into OSCAR. OSCAR shows the whole night's sleep, 8:14 usage, AHI 0.61. Looking at just the first segment of 1:38, AHI was 0.0. Looking at just the first two segments, 4:15 total, AHI was 0.49.


It appears that what's happening is that while the information is being recorded correctly on the SD card, the display is showing the AHI as both the usage time and as the AHI.

From the National Engineering Manual for CPAP Machines N_210_UPFDOC Section 709.37:

Restart the machine and look again tomorrow.

The universal answer to every tech support problem.

Cold start: unplug--count to twenty--plug back in.

Hmmm....I did that yesterday because of the daylight savings snafu possibility.

I might try that again because I dried my hose with maskfit and the damn thing said I had 40 AHI and 3 minutes sleep. lol wtaf? I doubt it will change anything but hey what else can ya do?

I suspect I have lived in houses with poltergeists.
Sometimes, when sneaking through the walls, they trip over a wire.
