Tweaking Pressures has me totally confused.

[DannyPh]

I have been on the s9 auto set for Just over a week now and still trying to find the sweet spot with my Pressure range. I initially started with a range of 13 to 15 and the pressure stayed around 14.8 for the past three days. Last night out of curiosity I increased the Max pressure to 15.8 and this morning I checked the LCD screen and it said my pressure for last night was 15.6. With this said Now I am more confused than ever with the pressure range. Should I widen the Pressure range more or leave it set to 15.8 for a few days? With variable pressure ranges I have felt good each morning and AHI's have been good ( .06 ) this Morning. Just trying to Find the sweet spot on my Pressure range and any advice will be appreciated. It seems like the higher I raise the Max pressure the Higher My nightly average goes. Have I not reached the Needed Max pressure yet ? Thank You.

AHI's have been good ( .06 )

How can the machine calculate an AHI of 0.06?

If you slept eight hours that is 8 x .06 = .48 events for the night.

You could just set the maximum wide open, it really won't affect anything. The minimum pressure is a bit more important as having it too low could allow events to happen and it takes as the machine adjusts. Since your ahi is so low I'd leave the minimum pressure alone and maybe open the max. a bit but, your ahi IS low so there isn't really any reason to do anything.

Right now you are getting your numbers off the machine's LCD screen because you don't have a card reader/adapter...correct?

If so then what you are seeing being reported for pressure is the 95% pressure. All this means is that for 95% of the time you were at or below that pressure number...the OR BELOW part of the definition is very important. People tend to forget that part....you don't know where the OR BELOW part was at.
That's the same thing for the leak number off the machine also....95% of the night was at or below that number shown.

Number wise you aren't going to get much sweeter.

If you are sleeping great and feeling great...don't dwell on minute changes in numbers. It is unnecessary at this point.
Wait till you get the software up an running so you can see what actually went on.

(1) I don't think you can do good experiments with your own pressure until you have the software. You can't get enough information from the screen readout, as Pugsy notes, to really observe what's going on. Once you get the software, you will be able to see what has been going on, because SleepyHead will pick up everything, but until then you're going to be a bit in the dark.

(2) If you change too many variables at once, or you limit your observation period, it will be too hard to figure out what's going on. My dial wingin' has been very cautious indeed (discussed here: viewtopic.php?f=1&t=88125&p=807754&hili ... rt#p807024), in part because making changes sometimes makes things a little worse for me for a while, then when I get used to the change, my numbers improve. I try to give each change I make at least one week, and sometimes much more. (The only thing I've ever done just for one night is setting flex to 3--I've tried it a couple of times and it has always felt so horrible I haven't been willing to give it more time).

Yeah, it's a slow process, but my treatment is already pretty good, so I'm in no rush. I understand the excitement of experimentation on oneself, but, whoa, there, Pilgrim!

I would not be trying to tweak pressure's without good data (more than what you see on the LCD).

Further, I think you are making changes too fast. But get that card reader. They are ridiculously cheap. Radio Shack has one {url]http://www.radioshack.com/product/index ... d=11085371[/url] for $15. You can probably find it cheaper by mail (but have to factor in postage).

Really, you're missing out on a ton of good information that would really help.

Best Buy basic card reader is under $10

[DannyPh]

Well, I just purchased a 26-1 Card reader off of E Bay for $ 4.39 with free shipping. I hope I chose a good one. It is due to arrive on or before April 25th, 2013. I currently have pressure settings set at 13 to 16 so I will leave them there until the card reader arrives unless there are drastic changes in my Therapy. I already have Sleepyhead down loaded so Hopefully I can read my data in depth when it arrives if Sleepyhead co-operates with me.

Danny, you have the wrong humidifier listed (M Series)and you don't have your S9 Autoset machine listed.

Thank you Dori. I hadn't thought about changing my equipment with all the tweaking I have been doing with my Pressures.
