Why are hypopneas 10 seconds long?

That's the time of the event. No duration is indicated.

I am sorry I don't understand

What so you mean by "time of the event" duration is the name applied by the sleepyhead software? In the center column to the left of the Datetime. Those durations range from 1 second to 19 seconds.

The number to the right of the duration that starts with the date is labeled Datetime

I think SH is reporting the hypopnea durations, not recording them. For the S9 SH was reporting these with numbers that varied, and were always equal to or larger than 10.

At one time Mark was wondering what those numbers were that appeared in parentheses after an event.

Sorry about coming back to this after so much time. SH appears to be reporting that every hypopnea on a A10 machine lasts for 10 seconds. This is just a bug in SH. The A10 is apparently not reporting hypopnea durations, but if we take it on faith that it's counting them correctly, then the count reported by SH would also be correct. The only thing that SH is doing erroneously is reporting a hypopnea duration of 10 seconds, if indeed those numbers in parenthesis are intended to be durations, and I believe they are.

With Sleepyhead version 1.0.0 beta2 and my Resmed S9 I found hypopneas from 10 seconds to 44 seconds.
