CPAP to Autoset

Link, you have an exceptional ability to breathe out against stratospheric pressure - others have an exceptional inablility to breathe out agains far lower pressures.
In healthy human beings with healthy lungs, exhalation is not a result of muscular, effort, it's a result of result of relaxing the muscles (see " The mechanics of breathing " in the Encyclopaedia Britannica). By giving a person lower exhale pressure, you emulate natural breathing conditions - the expanded lungs/ribcage drop down and the exhale is more natural.
The benefit - of an easier exhale - and the cost of higher pressure have to be decided by each user in person.

Good point. I personally hate the feeling of breath stacking that I often get on xPAP. I sometimes have the irrational (I hope?) fear that I have developed interstitial pulmonary fibrosis and it's screwing up my lung compliance. Really, it's most likely just breathing out against hyperbaric pressures.

Some people do have obstructive apneas at the end of the exhale cycle -- EPR makes their results worse.

For the majority of people, the feeling of a difference between IPAP and EPAP is what gives them exhale relief. Thus, there are people - and I'll wager that not a few of them - for whom counting up from the EPR may be the right way to go.

Any apnea would occur at the pause before inhale or during inhale. Not during any part of exhale. It's simple physics. The airway will not collapse until the exhale is finished. But it's too fine a point to really make a difference.

I suppose counting up is one way of keeping the relief...but at the cost of increased overall pressure. Is the benefit worth the cost?

LinkC some of us have the issue of the soft palate acting like a valve that shuts on the exhale. When I've experimented with bilevel I've noticed it makes the condition worse than straight CPAP.

Since I was using 11.8 when set at 12max, I wondered if I was needing even more. I changed the upper number to 13. So for 2 nights now, I've been using 12.2.

Don't know that it's changed anything for me, good or bad.

And leaks are insane....they may not register as insane in the data, but I'm always fidgeting with my mask. I don't care how many adjustments I make, even if I start over and put the mask on by the book!! Eye leaks and chin leaks are driving me batty.

Maybe I will have better sleep and actually rest when that isn't a problem.....anyone have any crazy glue?

It sounds like it may be time for a different mask. There has to be one out there that'll work!

Unfortunately, I need an extra small full face mask.....Quattro is the only one.
