Strong correlation between movements, flow rate dislocations and appearance of apneas?

[Albatros]

As we can see, with each movement, there corresponds a dislocation in the flow rates, and an acceleration of the heart rate, but more interesting, often the appearance of OA/H's.

[Pugsy]

What are you using to record movement?

[Albatros]

To record the movement, I am using the O2 ring, which gives SPO2, Pulse rates and the Movements.
I had a recent Hospital Sleep full recording and it gave me the opportunity to check that my O2 ring Spo2 was correct.

Very interesting and important implication!

The operating theory with consumer XPAP devices is that disruptions of flow is caused by airway collapse, full or partial. The remedial action to this collapse is to apply additional pressure.*

However if some flow disruptions are actually caused by movement, the ordinary programmed remedial action is faulty.

In-lab PSG are routinely edited to remove events that are not caused by airway collapse.

* the exception being made for clear airway where it is surmised that the airway is actually not being restricted.

Gee.

The concept of "false positives" in reports.

Strange that's never been considered before...

Strange that's never been considered before...

Of course it's been considered before, but normally for standard domestic users it (false positives) is couched in speculation.
Use of an accelerometer (such as the ring) or recording oximeter can provide evidence thereby limiting the need for speculation.

Accelerometers and oximeters are inexpensive; can't imagine why XPAP manufacturers don't incorporate them in their consumer products.

That's easy!

Because it's a stupid idea.

[Max46]

Because it's a stupid idea.

It’s such a stupid idea that Resmed sells an oximeter kit.
And allegedly working with Wellue oximeters to sync via Bluetooth

To incorporate movement?

They are most assuredly not.

Read topic.

[Max46]

Read topic.

There is a topic that states Resmed is NOT studying /investigating movement sensor?

Could you please explain why you think that oximeters and movement sensors are stupid adjuncts to consumer machines?

My personal philosophy is that more information that relates to therapy is desirable.

[Albatros]

I agree with that. As long as the recordings are credible, the more different views we have of our night, the better it is.
And to get back to my personal case,which triggered the discussion, the fact is that the movement detection seems to be OK, as the movements detected are perfectly synch with the Flow rates and Pulse rates events.

[Rubicon]

...as the movements detected are perfectly synch with the Flow rates and Pulse rates events.

OK great.

So what?

[Rubicon]

Could you please explain why you think that [movement data from] oximeters and movement sensors are stupid adjuncts to consumer machines?

No.

You explain what you're going to do with that data.

[ChicagoGranny]

WTH?! An AHI of 1.2 and obsessing over a chart.

Some people should go through intensive training and certification before being allowed to see data.

Your sleep study already showed your sleep is disrupted by PLM's.
