just how does the xpap determine hypopnea

How it determines hypopneas is described in my Autoset 10 clinical manual - isn't it in yours?

Page 19 of the Clinical .pdf manual:

Events (AHI) per hour
Apneas and hypopneas measured per hour for one day.
An apnea is when the respiratory flow decreases by more than 75% for at least 10 sec.
A hypopnea is when the respiratory flow decreases to 50% for at least 10 sec.
The Apnea Index (AI) and Apnea-Hypopnea Index (AHI) are calculated by dividing the total number of events that occurred by the total mask-on therapy period in hours.
Note: Under conditions of high leak with EPR enabled, AHI detection may not be optimal.


You're welcome.

Bummer. I guess they figure that by the time you get into an ASV simple definitions are not needed?

no

Page 13... get someone to read it to you.

No, it's there, he just needs someone to help him with the big words.

I would have said: maybe a picture could help - but he already looked at his charts and couldn't see it - so that seems to be no option at all.

the problem is not the definition

the question is how they are claiming to have met their definition from that data

i dont see any hypops when they claim them
i do see them when they did not

no snore
no flow limitation
no flat topping of the breathing wave
no lack of air flow or reduction in Vt
nothing
and they declared a hypop

You do know that no one can help you understand why a picture does not look the way you think it should, when you don't share the picture don't you? If you want help, we need to see the facts - not your interpretations.
Since you are not interested in a serious answer, I'll vote for your Remed is guessing theory.

you dont know jack so you dont need anything

my question is clear
HOW do they decide that the flow was limited to declare a hypop

you dont need the pictures
just some knowledge which you have none of
just tell us HOW they decide there is a hypop not the criteria for it
the question is how they know the flow rate was limited by a hypop

I will try to help you - I do love a challenge.
HOW they decide there is a hypopnea is by APPLYING the criteria. That is how criteria is used.
What is the criteria that your machine uses???? Please state it verbatim.
Once you know that, you can then APPLY it to your data.

I've stayed away from Alphabet Boy and his conflicts with everyone here, but this thread is just too much.

It's obvious that xyzzy is an internet troll. Why do people keep responding to him?

en. wikipedia. org/wiki/Internet_troll

If there was ever a discussion that called for a picture, this is the one. And yet he won't supply a picture, even though people have specifically asked him for it.

INTERNET TROLL. AND YOU'RE ALL BEING PLAYED BY HIM.

I'm surprised it's lasted for so many months. And I'm looking forward to being called a "libtard" by him in response. Nobody has ever accused me of being a liberal in my entire life. And there's a first time for everything!

you are truly a jerk

i know the criteria

i am saying the data they show us does not support their claiming hypopnea based on the sleepyhead graphs

so do they have some other magic method that they dont release to the outside world
or do they just guess

When I apply my machine's criteria to my data, it makes perfect sense why the hypopnea event was flagged.
I don't know what the criteria is for your machine since you did not state it. Nor can I comment about how your data looks relative to your hypopnea event flag since you did not show it.

Ask a Real Engineer, I've heard they know everything! Jim

============

my machine does not tell HOW i t determines the criteria was met

there are no decreases in flow or anything else that would indicate hypops on my data
it has to have something else hidden that it uses but does not end up in sleepyheads printouts[/quote]

Maybe your right.
Maybe your wrong.
Maybe your confused.
Maybe SH didn't put the event flag in the correct location.
Maybe ...

Because, when he’s only an engineer because Mommy gave him a big plastic hammer and screwdriver set for his last birthday, all these graphs and science stuff are a little beyond his intellectual grasp.
