Sleepy Head Question Events Tab

I am looking at the daily and click on the events tab, it shows Obstructive Apnea 1 event
it shows it happened at 05:11:09 (6). I wondering what the (6) means?

I also notice that I am seeing alot of Unknown 0B 5 events. Does anybody what know what that could be all about?

Thanks in advance for the assistance!

The length of the event

For ResMed users it is the length of the event in seconds.
ResMed machines actually flag even duration but Respironics doesn't (on Encore there is no event duration record)

For Respironics users...it's a close approximation to length of the event in seconds. Obviously apnea events have to last 10 seconds to get the flag and 6 isn't 10 seconds. Respironics users "markers" and that's the marker. Don't ask what a marker is..I don't know.
If you zoom in (click on that single event) your graph on the right will zoom in real close and you can try to count the actual seconds.
It's hard because zoomed in close enough to count seconds also makes it hard to see where the obstructive/flow reduction starts and stops.
I studied a lot of those events a while back and the ones that had less than 10 showing in parentheses were right around 10 seconds in duration. Those with higher numbers were real close to what it would have been in seconds with a maybe 2 second variation sometimes.

So while not exactly event duration in seconds...it's going to be real close.
Close enough if that you see single digits showing in parentheses then it most likely barely made criteria for a flag at 10 seconds and f you see 45 in parentheses...it was a long event.
