Sleepy event times question

On the events tab, when you click on an event, say, obstructive apnea, what do the numbers in parenthesis after the time of each event mean? All I can think of is that it refers to the length of the event. Here's a shot of some of last night's data:

I always thought it meant the number of seconds the event lasted. But I see you have apneas marked 9 and 7 and to be an apnea it must be greater than 10.

I mostly stick with ResScan because SH seems to have a lot of bugs.

Agree.....+1

With the ResMed machine....yes the numbers in parentheses means duration of events in seconds because the S9 actually records event duration and ResScan also reports the duration in seconds.

The PR S1 machines don't actually record event duration so the number in parentheses are not exactly event duration in seconds. That's obvious because we can't have a 9 or 8 or 7 second event duration...they have to be 10 seconds to earn a flag.
Instead the number in parentheses when using the PR S1 machines are actually "markers" and we are never really told what those markers mean or do but when using Encore software there is a place for "total time in apnea" so I suspect it is some sort of timing mechanism.
It's not exactly seconds but it is really pretty close. If you zoom in on each flagged event you can count the number of seconds up to a point. It's kinda hard to see the beginning and ending of each event when zoomed in close enough to count seconds.
I probably counted a hundred of them to see if I could spot anything special. Mostly the events numbers in parentheses were probably within 2 or 3 seconds of the manually counted seconds.
Those 7 or 8 or 9 numbers in parentheses were almost almost barely 10 seconds in duration and when I saw a 45 in a hyponea flag...it was definitely close to 45 seconds in length.

So with the S9...yeah, event duration in seconds
but with the PR S1....not exactly but close enough for government work (as they say) ...it is isn't a perfect exact duration of event piece of data but it is close enough to get the idea if the number is low it was short and if it wasn't short...probably longer...anyone can always zoom in and manually count the seconds to get a feel for how it goes.
