Airsense 10 climate control auto humidity too low?

So I have been using my CPAP for a few days now and last couple night I have been waking up with a dry upper lip and a bit of dryness in my nose but I use the climate control auto mode. Does the auto mode scew a bit low or could it could it be someing like the high summer time humidity where I live, that my Simplus mask has a fairly high leak rate, my somewhat low starting pressure, or that have a loft bed and I have to put my machine on the built in shelf under my bed and I have a window on the topside of my bed but not on the underside. I have tried looking in sleepyhead to see what the auto mode was putting my humidity at but it says I am at manual mode 4 (I am guessing that is a bug with sleepyhead)

Auto mode with the S9 is 80% humidity but I don't know about the AirSense auto mode.
See if it mentions it in the manual. I don't have time to look through it right now.

If I remember correctly auto humidity is either 80 or 90 % on the AirSense but I could be wrong. I know it isn't on the low side.

Even with maximum humidity it may be that your body just dries out easily for some reason or other.
Some people have used something like chapstick on their lips to keep the lips from drying out.
For the nose...get something like Simply Saline and use it frequently during the day to help hydrate the nasal mucosa.

I don't know where you are, but, most places in the US are very humid this time of year. I have turned off my humidity completely, but use a Carmex lip balm before bed and it helps a lot.

I had to increase the humidity level on my AirSense 10... I have mine set at 7 (higher than Auto had it set at) and it is way more comfortable for me. My machine was set to Auto at first also. You can change the humidity level without going into the clinician's menu. Go into My Options. I think you have to first select the Climate Control option and then you can change the humidity level. There are directions in the user manual. The only issue I had in making the change was that the option wasn't labelled "Humidity" at first when it was set to "Auto". I can't remember exactly but I think the option was "Climate" or something like that. When you press the select button for that option, it changes and you can select the humidity level you want. I think there is also a Resmed coaching tip on how to make this change. I think in My Options you can also change the temperature.

I live in north-western Missouri some nights we have humidity at almost 90%, I tried taking a nap without humidity and I could not get comfortable and had to turn it back on

You are just north of me and despite the high humidity outside..it isn't always so high inside the house especially if you are using air conditioning.
Besides...the machine won't do much if the inside humidity is high...it doesn't put out X % of humidity on top of what is already there.
You will find that when the inside humidity levels are lower you will use less water than when the inside humidity is higher. The machine has a sensor for ambient humidity and that's its starting point and it then adds humidity up to whatever you have it set for if you are using the heated hose.

So if the ambient humidity is 60% and you have the machine set for 80% the machine will only add enough moisture to make it to the 80% mark. I prefer a heated hose so that the humidity is constant no matter how it varies in terms of ambient humidity.

It's possible that even with maximum humidity setting that the machine simply can't add enough moisture to keep the tissues in your nose or your lips from drying out. Maybe you are taking meds that tend to dry out people or maybe you just are one of those people who find that they dry out easier than others.

Humidity needs or preferences are highly individualized and what one person needs isn't necessarily what the next person needs...heck a husband and wife sleeping in the same bed might find that one of them prefers minimal humidity and the other prefers to be snorting water (that would be me).
So this is something you have to figure out yourself as to what you as an individual prefer. It's a lot of trial and error.

Right not we don't have AC so I sleep with windows open and fans on, so outside and inside humidity should be close to the same. The machine is adding some moisture to the air because there is less water in the tank than I put in (a little less than half the tank after about 8 hours). The manual Pugsy put up said auto will aim for 85%, so I don't know if the room humidity is bouncing around all right or what. The only meds I am taking is Flonase, could that be part of my issue?

I don't know if the Flonase will dry out the nasal mucosa or not. It might I suppose. I would get some Simply Saline which is just a bit of salt water and use it often during the day. It sure won't hurt anything to add it.
The dry lips or skin...obviously the Flonase isn't the problem there. Sounds like you might be one of those people who just get dried out easier than others. Treat the dry skin like you would any other dry skin with some sort of moisturizer during the day and add a barrier at night to lessen the drying from the air blowing on the skin.
Think about it...if you were going down the road in your car and stuck your head out the window for a little while the skin would get a bit dry.

I think you can manually set the humidity and temperature independent of each other...take it off auto.
And set the humidity to the maximum setting but I think that only gives 90% which I doubt is going to add all that much moisture. Worth trying though and won't hurt anything.
Being able to set the air temp might make things a little more comfortable though.

Even with the windows open and the relative high humidity we have been having lately it's not going to be quite as high inside as outside. If it was the same then it would rain in our bedrooms when it's raining outside.

My machine is set to Auto and I use it for over 8.5 hours each night.
I fill the tank each night and there is only a dribble of water left in the morning, so it must be adding just about as much humidity as it can.
Mouth dryness is tolerable at this setting.
I am in South Australia. It is winter at the moment. I'll be very interested to see how it goes in summer, with humidity regularly around 10%. (very hot dry summers)
