ASV Machine Pressure.

Sounds good to me Larry. I think we found the ideal PS by trying both directions.

Here is last night.  I changed PS min to 4.0 from 4.4.  I think I had mask problems and want to give it another night.

We have already concluded that your results vary and our objective is to find the best long-term comfort and rest for you. It seems your events occur randomly and may not be related to the settings.

This is last night.  I tightened mask around 5 am.

[LarryRapp]

Actually I tightend the mask around 3:30 EST.

This is last night.  I don't know why this is so high.  Before we started this last series of changes, my AHI was almost always below 1.  The only thing which has changed is EPAP.

[LarryRapp]

After thinking about it for a while, I realized that another change is that I am no longer using a chin strap.  The chin strap didn't do much for my chin, but it did help a lot with my beard.  It helped stop leaks.  If I can remember to do it, I'll use it tonight after loosening my mask.

I think we also tried a cervical collar in the past and you didn't tolerate it. The events here look kind of clustered, and I think it depends on what position you are in at the time whether you have more or fewer events. Very clearly, the event clusters correspond to leaks, which further suggest a positional aspect. I don't think setting changes will help.

[LarryRapp]

Thank you.  The more I think about it, the more I agree,  If I can remember, I will definitely try to use the chin strap tonight and make no changes to the settings.

This is last night.  I used the chin strap and slightly loosened the mask, but it was still tight.
