Sleepyhead data - Help needed please

Tube temp 80 degrees and relative humidity 85%

Climate Control Auto

Thanks, that's on the AirSene/AirCurve models.
The S9 is 80% and 80 degrees. Not a huge difference but a little more humidity. I guess they are finding that more people need a little more to come up with that % as the "usual".

So Hannibal is getting on the higher end of humidity delivered.
Doesn't seem to notice any huge difference one way or the other with a hot shower.
Previously had been using passover humidity with the old machine.

I think an experiment to try at some time (doesn't have to be right now tonight) is to try a more middle of the road humidity setting and hose temp at whatever is comfortable and doesn't allow condensation.
Manual settings vs auto..maybe 4 or 5 humidity and whatever hose temp feels good.
4 or 5 is more middle of the road with the AirSense machines which I think will go to 8 in manual.

I checked the display when I woke up and was disappointed to see an AHI of 6.2!

sleep varies from hour to hour and night to night, which is why, when you're fine tuning things, you want to work on averages, not single nights.

all because there's a squishy meatbag in the middle of this whole process.

Thanks again for clarifying. Does that Flow Limit look bad or is it me?[/quote]
I've seen worse, but yes, it's bad, and part of the reason the pressure is pegged at the max except when the huge leaks happened.

Squishy meatbag, love that term

.
The Tube Temperature is set to Auto (80°F [27°C]) and
Climate Control adjusts the humidifier output to maintain a
constant, comfortable humidity level of 85% relative humidity
while protecting against rainout (water droplets in the air
tubing and mask).

Yes, Auto is equal to 27°C and the ResMed Tech told me this was 85% humidity, thank you both for the info and consideration of what I may try.

Didn't look at my readings this morning, felt that I slept really well, had about 7 hours but felt tired when I awoke.

So I spent the last week not particularly chasing numbers and left my APAP settings as they were. I took Pugsy's advice and didn't check my basic data until later in the day. Before checking I was giving myself a daily score out of 10 based on how felt, and then checked my basic data on MyAir (yea yea, I know!) to see if it was roughly what I expected, and it pretty much was! However, it's time to look at the data properly (with your help?). I am only posting the last 3 nights as I don't want to ask you to study a week's worth.

As and experiment on the final night, I taped my mouth - not sure if it made a difference apart from my AHI being higher, let me know what you think - and yes I've worked out how to imbed images from Imgur!

TUESDAY (Mouth Taped):


Let me know if you need any other graphs

[Pugsy]

You got them embedded but I can't read any numbers. Too tiny. I can't change it to view image and make it any larger either.
Which code from the little box at imgur did you use? I can't figure out if you shrinked the image or not. If you did..don't. Use full size and choose the last line BBC code (AFTER you have clicked on Large thumbnail).

Can you get me the flow limitation graph from Tuesday?

[Hannibal 2]

Apologies, Is this better? Flow Limit to follow

TUESDAY - With Flow Limit:

[Pugsy]

Much better thank you.
The flow limitation graph pretty much shows what I expected based on what the pressure graph was showing.

It does appear that maybe those large leaks seen earlier might have been related to mouth breathing based on the absence of large leaks last night but I wouldn't have bothered taping my mouth for that little bit of large leak assuming it was all mouth breathing.
For me taping sort of disturbs my sleep more than a little mouth breathing might disturb my sleep and I am okay if I have small brief times in large leak as long as I sleep well. I don't have to have a nice perfect leak line to be happy but some people do. I learned a long time ago that my sleep quality was more important than good math scores as long as I was sleeping good.

I don't know why the AHI is higher with the tape except that maybe it was a fluke night.
Your large leaks the other nights were so brief that they couldn't falsely lower the AHI by much if any if the machine missed something (which I doubt it missed much).

[Hannibal 2]

Thanks very much for commenting, will probably continue with the nasal mask for a little longer in that case. Any point in changing any settings? I was thinking Max down to 15 maybe?

[Pugsy]

How often do you hit max of 15? I saw at least one max of 15.88 in the statistics.
Unless the pressure going above 15 is causing a problem...wake you up or bloated belly...there's no need to limit the max. The machine won't go to where it doesn't need to go without a good reason.
Looks like the good reason is probably the flow limitations based on the increase in flow limitations corresponding with the pressure increases.
Flow limitations are part of the algorithm that is used to drive the pressures...the machine is designed to respond to flow limitations. Now sometimes those flow limitations need a good killing but sometimes the need to kill them creates more problems than letting a few FLs slide would cause.
The higher pressures aren't causing centrals and unless you are having belly issues..I would leave the max higher. Now if you are having belly issues...sure limit the max and see if it helps.

Your flow limitation graph is not really all that horrible. I have seen much worse.

Having the max higher doesn't affect how the machine responds when it is not going higher.
It doesn't make it work any differently in terms of overall response time. If the machine could go to 100 and you set the max at 100...and it never went above 15 or whatever...it wouldn't matter what the max was set at.

[Hannibal 2]

Understood, I think I probably just need to get to bed earlier to get a more beneficial outcome, which I'm sure you suggested in the first place

[Pugsy]

Yeah, I think I did.

3 nights above..not one night over 7 hours and one barely made 6 hours.

The best numbers in the world won't substitute for lack of hours.

[Hannibal 2]

Absolutely right! I keep telling myself get to bed at least 30 minutes earlier, but seem to find it hard breaking my routine (habit). It's not like I'm feeling terrible during the day, just the knowing how much brighter and alert I have felt when I get it right, and I want that feeling more often.
I think my sleep tech referred to it as 'sleep hygiene', getting into good habits, more sleep, less alcohol and caffeine etc etc.
It's easy to just blame the machine when you just haven't adopted good sleep hygiene!
