Re: Flow Limitation

And I doubt there are many folks (even those without Apnea) that have a pure sinewave breathing pattern. Yes, absolutely. Now to complicate the explanation (and perhaps give some credit to the software engineers), the evaluation for air flow pattern not only looks at the most immediate shape, but a...

Re: Flow Limitation

I'd add a bit of nuance/correction to Miss Emerita post. The scale is 0 to 1.0 wherein 0 is supposedly great and 1.0 is horribly bad. It is an arbitrary scale, and the your instantanous values determined by Resmed and others are indeed proprietary (and perhaps defy any coherent explanation). As I un...

Re: Does 10 EEG arousals/hour mean sleep apnea?

If there is evidence that your body is not trying [/i] to breathe, it's assumed that a blockage in the upper airway is NOT the cause of the apnea, and the event is scored as a central apnea. Perhaps a better way: " If there is evidence that your body is not trying [/i] to breathe, it's assumed that...

I’d recommend that you ask your doctor for a Holter monitor to see what’s going on.
Agree, look particularly to rule out Proximal AFIB.

Re: Precise Meaning of MIN and MED

Choosing the appropriate measure depends on the context and the nature of the data. If outliers are present, the median may be a better representation of central tendency. However, both measures provide valuable insights depending on the situation.

That's why your brain woke you up - to make sure you get over that obstruction and breath out properly. No mystery.
If so (obstruction only affecting exhalation) might have anticipated choking - too much air - rather than gasping (too little air). But whatever, ….what goes in must come out.

Re: Woke Up Gasping

Sure. Unless there is a significant leak , the volume of air inspired should be close to that of the volume expired. In your beginning three breaths of your original post the volume of air exchanged between 21:04:36 and 21:04:40 is fairly equal between Inspiration and expiration. ( the area under th...

Re: Woke Up Gasping

Referencing the chart in your original post,
What I find to be significant is that your expiratory volume is significantly less than your inhalation volume. If the flow curves are correct, air was accumulating over many breaths (11).

Re: Inspire and hypoventilation

How could it possibly help? Exactly. What I understand is that the INSPIRE delivers mild stimulation to the tongue nerve to prevent the tissues from becoming flaccid. If a patient is not experiencing airway obstruction, but rather "shallow breathing", stimulation of the tongue will accomplish nothi...

Re: Inspire and hypoventilation

I make it a practice to be very skeptical of what the marketing/PR folks say about their product.
