Short apneas - official definition

I'm reading the Resmed definition of apnea and hypopnia.

"Apnea" means "no breath." An apnea happens when you stop breathing for 10 seconds or longer during sleep.

"Hypopnea is a partial blockage of the airway (shallow breathing). During a hypopnea, breathing is reduced by 50% for 10 seconds or longer."

OK.

So what happens when it's an apnea of 9 seconds, or a hypopnia of 49%?
Is that unreported?

The medics at the hospital go by data reported by my resmed device so what are they seeing and does it reflect true health?

An apnoea or hypopnoea of less than 10 seconds won't be reported as an event, in the same way they're not reported on a sleep study, as that's the cut-off point.

It's a suspiciously round number I wonder how they arrived at it?
I asked the People at Castle Hill and they didn't really enlighten me on it, but I was told that it's normal for people to have apnoeas, which I didn't know.
I thought normal healthy sleep was no apnoeas so that is the thing to aim for, but apparently they are ubiquitous.
It's can be a long time before we find out our basic conceptions are wrong, at least speaking for myself.

Next I want to find out about UARS, which Dr Park says is a problem, but the medics at Castle Hill didn't rate as an issue.

"How did you fasten it?I suppose you could do it with tape or elastic bands. Cut up an old fleece jacket, wrap it round the tube, strap it up, bit of velcro. That sort of thing. I hadn't really thought of that."

"Did you try a sleeve for the tube, Jonathan? For rain out? I got one off ebay for a few quid and I think it helps. It's a fleece sleeve  you zip over the main tube."
