leaks (mask or mouth?) excessive tearing (leak or dry mucous?)

Zoom in more, the interval should be around 909 seconds to two minutes.

There you go:

Is that zoom in proper?

As the flow rate's amplification is low that seem to be mouth leaks. Right?

That would make sense. In the event of a misplaced mask it would be high or flat?

That would be the same amplitude, just leaks. But I already see if the leak is a plateau that mean mouth leak.

Is there an explanation to why a misplaced nasal pillow mask could not be a plateau?

For me not really, but I read lots of comments from seasoned users whose claimed, it's mouth leaks, there is plateau form.
AndI think plateau not obligatorily equal to mouthleaks.

In my personnal opinion, the mouth leaks should be have different repercution on the flow rate. (depend if it's just a leaps leak, mouth open leak, traying to breath by the mouth leaks)

I'm not a specialist, it's just my reflexion. And lots of people here are not engineers, just experiemented user which are based a lot on the generalities encountered and not on the technical reason.


If you want to solve leaks problems, you can tape your mouth and see the differences. (sparadrap is the best)
If leaks persists, that mean you have mask leaks.

In my case a typical mouth leaks looks like this:

   

Explanation: mouth breathing can't occur if tongue is in place (TIP).  We see a no-TIP-situation from 5:15:50 to 5:17:10; flow rate shows that typical horizontal passing through the zero line (since the air escaping through the mouth can't possibly be detected by the machine).  From 5:17:20 we have TIP, hence no leaks and a (for me) "normal" flow.

That's why I am sure that a mouth leak occurs if the leak rate looks spiky, at least for me:

   

In contrast to my mask leaks (mouth leaking was impossible since my mouth was properly sealed):

   


Flow was sinus.

Ya exactly, specially the inspiration amplitude is increased when leaks stop.

And you should have an impact on the tidal volume too.

Humm it looks like mouth leaks from the form but the respiration amplitude doesn't seem to increase. However The tidal volume does when the leaks stops.
