Reasons for not setting max pressure to machine max on automatics

A certain poster reads random stuff elsewhere, and posts it here,
REGARDLESS OF VERIFIED FACTS.
Self--aggrandizement, pure and simple.
Retired, or unemployed, bored out of his skull, only thinks of himself.
I can see it all.
I'd hate to see how filthy that sofa has gotten since he arrived.

It might be just me, but i think, none of those reasons justify using a low pressure that doesn't treat the apnea.
A pain would need medical investigating.
You fix a mask leak, you don't reduce pressure.

"Dryness" struck me. In my years here, I never once heard a recommendation to decrease pressure to resolve "dryness". My, my.

Maybe when he changed the pressure he knocked his water glass over on the air intake. Jim

A "general" rule doesn't mean a set rule. It means that it is a rule in general, but not always.
In other words, your post was worthless at best.

How's this different from any of their posts?

My two cents, for what it's worth...

I've an S9 autoset and I set my minimum pressure to 1 below my Rx pressure and the maximum pressure to 20. This seems to work for me.

The majority of nights when I look at my machine it shows the final pressure pretty much on my Rx pressure (10.6) +/- 2. Indeed -- looking over a year's result the 95th is still 10.6 (kudos to my sleep doctor for nailing it). Occasionally it will hit 11+ and a couple of times over the last 8 years it hits 12. The way I see it, I let the machine "figure" when I need the slightly higher pressure.

I think the machines, particularly the APAPs, have come to a point where they're capable enough to work out at what pressure to go to -- particularly the ones that can detect central apneas.

Since it doesn't look like it ever goes above 12, setting the max to 15 would not cause any behavior different than if it were set to 15 (or even 12.5). Nevertheless, I also have my max at 20. I once did hit 17, but that was highly unusual.

For some, the higher pressure could cause problems such as leaks, discomfort, or "Central" events that were not experienced at lower pressures.

Generally correct! However, if these problems only occur at the higher pressures, then I'd rather have everyone comfortable with his(her) therapy than putting the machine away in the closet.

Some can leave their "top end" at the machine limit, some can not.
Obviously, the lower end needs to allow therapy to occur, even if
you have to start too low, and work up gradually.
Success is the objective, and everyone is different.
