SleepyHead Daily Graphs - No Event Graph = No AHI?

Post by meissen » Wed Nov 21, 2012 6:28 am

As the title says - I imported my SD card data last night and was surprised to see that there was no Event Flags graph and more importantly my AHI was 0.0. Is it at all possible that the SD card just didn't get the event flags for the night or did I truly have an AHI-free night? The night before I only had 4 flags - 1 obstructive and 3 hypopnea - so is it possible I did THAT good last night?

To further my reasoning for not trusting the results - apparently last night around midnight I thought it'd be a good idea to take my mask off and turn the machine off. I remember waking up a little after 2am and thinking "WTF? Why is my mask off?" so I put it back on and started the machine and slept with it on for the next 3 hours until I got up for the day. All in all I only had the mask on for just shy of 5 hours.

Meissen,

It happens every now and then that you have a completely clean night. Congrats. It doesn't happen often, well to me anyway.

Yes, it is possible that you had a perfect night. Especially since you really had minimal events the night before.

That said I don't want to rain on your parade but just wanted to tell you about a little S9 bug that sometimes gets the machine sort of "stuck" reporting the exact same thing and often it is 0.0 everything. Doesn't happen often though and there is no reason to suspect that it has happened to you. If you see a perfect 0.0 for several nights in a row then we might wonder because we would expect to see a little something every now and then.
If you want to make sure that the 0.0s are real and not a "stuck" thing all you need to do is unplug the machine from electric source for a couple of minutes and then plug it back in and let it "reboot" the internal firmware.
Sort of like what we do when we have to reboot to get rid of cobwebs in a computer.

You probably just had a perfect night but if you see the exact same thing night after night...do the reboot thing.
It doesn't hurt and if it is stuck it will remedy things with the next night of data. If you still have 0.0 then you know you are just doing really well.

Ah - well, considering my S9 machine is currently in the trunk of my car since I'll be going straight from work to my in-laws tonight to stay with them overnight, I guess I inadvertently covered the reboot part

Hi my event graph doesn't show any thing but I had 17.50 events. When I go back all the dates show no event graph how do I fix this ?

There's a little drop down menu in the lower right of the daily view that says "graphs." You can turn event flags on and off in that menu. That might be your problem.
