Hypopneas ten seconds only ???

[fitmart]

Now that I have had my CPAP for over a year, I have been looking back at my Hypopneas.  I have no OAs and only a few CAs but 90% of my apnea are Hypopneas.  When looking at sleepyhead, there is a number beside each event which I always assumed was the duration of the event.  My OAs and CAs have a variety of numbers ranging from 10-15.  However, my Hypopneas are always 10.  I mean every single one of them for every day of the year.  Would this just be glitch in sleepyhead?

Thanks

The time is reported by the machine and transcribed by Sleepyhead. You would have to look at the chart Flow Rate where the events occur to see if the duration is 10 seconds, more or less. You can click on the event and see a shaded area that the event includes, and you should see attenuated breathing rate or volume there.
