Here's my two cents:

1) Sure, it's worth exploring Auto mode. Set the min pressure high enough where you don't feel like you're suffocating when you're trying to get to sleep. Given that you've been using straight 15cm for several years, it's very reasonable to leave the max pressure at 20 to see where the machine wants to take the pressure.

2) If you wind up not liking Auto mode because the varying pressure tends to wake you up, you can always switch back to straight CPAP once you have a couple of weeks worth of APAP data. The beauty of owning an APAP is that it can be run in either mode. And you can use the APAP data to figure out a good starting value for straight CPAP if you decide to switch back to straight CPAP.

3) Since you've been sleeping comfortably for years and years with your old REMstar while NOT using Flex, I'd say turn EPR OFF. My guess is that since you might just find the pressure changes caused by EPR to be annoying and distracting since you are used to a fixed pressure blowing at you throughout the entire inhale/exhale breath cycle. And annoying and distracting things make it harder to get to sleep.

4) You say you're looking forward to trying a heated hose. Heated hoses presume that you are using the heated humidifier. It's well worth trying, but if you soon feel like you're trying to get to sleep in a swamp, then consider going back to a regular unheated hose and turning the humidifier down or off.

Thanks everyone.

One more question. I see some machine had bad seals that caused noise. Are those seals user replaceable or will the machine have to be sent in if I get a noisy one?

In my experience this is a very bad idea. The machine struggles to cope with such a wide range and tends to top out at a higher pressure than I need and stay there. Narrowing the range in my case to 11-16 prevents it from flat topping at the top end, which it did when I ran it wide open.

A lot of DME's set you up with the range wide open (or so I have heard) and I think it's a bad idea and makes it harder to use the machine properly and results in failure to get good PAP therapy..

resmed series 9 machine

Positive airway pressure device

h5i with humidifier

I have the full mask. Mask was too tight fixed that. There is tremendous
air pressure. No leakage on mask. But is it normal for air to come out thru
the tubing connected to the hose.

I can not stand the air pressure. My lungs actually hurt. Is the air
pressure too high. Did i just need the nose breathing mask.
I think i was hyperventilating and breathing hard because of too high
air pressure.

I was told 10% of people use full mask.

I went thru cpap test at hospital.

Struggling any help is appreciated. Something is very wrong.
