My next experiment....the AirSense 11 AutoSet

[Pugsy]

You are just going to have to lower the settings and see if your nose acts up.

Yeah...but I shouldn't have to. I shouldn't be made to make myself ill just to keep my nose happy.
When my nose acts up it is with a vengeance and I am miserable for several days. It's so much more than just an occasional sneeze or tiny bit of congestion.

Well, there are a lot of things that we don't want to do, but end up needing to do anyway. But it's quite obvious that the two machines have a differing setting for the numbers in the menu. It would be different if they had actual % humidity settings instead of numbers like a stove. If you are getting rain out at 86F tube temp then the saturation is at 100%. So it is obvious that you need to drop a number or two on the humidity setting. It is my understanding that on the AS11 the auto humidity setting is 80% humidity. I was wrong. From the manual: Climate control auto setting, adjusts the humidifier output to maintain a constant humidity level of 85%. And it will self adjust to the varying room humidity. And you can change the tube temp manually while in auto setting. So you ramp up to higher temp you like and keep the 85% humidity.

I suppose you could look on Amazon and buy a cheap Hydrometer and measure humidity directly to get an actual % number.

I have one.

I have tried the "auto" setting for humidity. It was a disaster in terms of what happened to my nasal mucosa's response to becoming too dried out.

You don't seem to understand that after over 15 years on cpap (and dealing with rain out long before heated hoses) that I know my nasal mucosa's needs and I know what happens when they aren't happy.

I just love it when newbies want to tell cpap veterans what they NEED/HAVE to do even after being told why it isn't a desirable choice. If I can't keep my nasal mucosa happy then I can't use cpap...or I won't use it.
I want/need more than 85% humidity. So please don't go telling me what to do. You haven't earned that right yet.

I am going to give it a couple more nights and then decide if I want to sell it or not.

I want hassle free and that's a critical need of mine (besides all my other preferences). So far that need hasn't been met with this new machine.

I have such fragile sleep now as it is what with the back/pelvic issues....I sure as hell am not going to deal with my already fragile sleep being fragmented even more by rain out or angry nasal mucosa when I have another machine that I can use at the setting of 8 (without hose cozies) and not have any rain out at all. In fact I have 2 such machines.

This is just a couple of thoughts.

> If your humidity is OK at your preferred setting, can you manually raise the tube temp a bit to stop rainout?

I tested the heated hose and it appears to be working properly. I verified hose air temp with a special thermometer and it is heating and it registered 86 degrees.

And I have the heated hose set to 86 degrees already which is the maximum heat I can have or I would gladly increase the hose air temp more.

So it's working correctly and I can't go any higher with the hose air temp.

Last night I reduced humidity setting to 6 and didn't get any rain out last night but then that's just one night and I already had a night (at a higher humidity setting) where I didn't get any condensation so I need more nights to see if this holds true.
Had a little bit of sneezing today from the lower setting (and dry nasal mucosa) but it wasn't as bad as I have had at other times. If it doesn't get any worse than this I can use the setting of 6 if it doesn't cause the rain out....so more nights are needed to be sure.

Gee Pugsy. Maybe try a little grace instead of vitriol. Or just make it clear that folks who haven’t been on cpap for 15 yrs need not reply. Hope your Christmas was a good one!
All the best to you.

[jsmit86]

Pugsy- I hope this works out for you.
I currently have an AirSense 11 AutoSet, and previously used an AirSense 10 AutoSet.
For me the therapy has been pretty much identical. I still have the 10 as a backup.
I appreciate your knowledge and massive support of this forum. May God bless you.

[loggerhead12]

One change last night was a reduction in humidity setting from the 7 down to a 6.
No rain out but need more nights.

I had to turn the humidity down when transitioning from the 10 VAUTO to the 11 Autoset. Like yours, mine does not run out of water either. I use less than half a tank a night.

I agree with Dog Slobber. Humidity is science. The machines humidity settings aren't science, they are an arbitrary setting.

What is the medium setting mean between two differing models of electric stoves from GE? Who knows. One may burn your eggs and the other cooks them perfectly.

You are just going to have to lower the settings and see if your nose acts up.

@Pugsy I agree too. I remember seeing a table somewhere, that detailed the differences between ResMed models' humidity settings. A 4 on one led to higher humidity than a 4 on another - couldn't find the source when I searched for it now and I don't even remember if the table had infor about the AS11 or only older models.

However, since condensation is a science, Pugsy's rainout is informing us hat something in the AS11 is causing the generation more humidity than the identical setting on the AS10.
Which means that once we leave auto mode for the humidifier, choosing a lower humidity level on the AS11 than on the AS10 may leave Pugsy's nasal mucosa as happy as before.

Pain and disrupted sleep can make most of us testier.

Last night was a change to regular autoset mode and response being changed from standard to soft.
Soft response doesn't seem to be a choice option when in the "for Her" mode.
To be honest I couldn't tell any difference one way or the other....shrugs.

I need to re-evaluate the humidity setting of 6.....it is causing some minor issues with the nasal mucosa.
Not having rain out though.

Only had 3 OA events flagged last night and 2 of them were false positive arousal/awake related flags. Only the last one appeared to be a real asleep flagged event.

I did have one RERA flagged. I never get excited about one of anything.

Notice the FL graph...not nearly as active as the For Her FL graph which is why I say the for Her mode makes mountains out of mole hills. What little activity that we do see from last night could be from the minor nasal mucosa issues I mentioned above.

Don't know what happened with the data right before the 00:00 time frame. Glitch in the data is all I can think of.
If we had lost power (or cat stepped on the on/off button) then the pressure should have dropped upon reduction of the blowing but it didn't drop....it stayed the same which points to no loss of power.

Yeah and my patience level is sub zero right now.

Especially when someone apparently pays zero attention to why I explain why I don't want to do something when that something causes me big problems and then that someone proceeds to say I have to do so and so with no thought to undesirable results it might cause and presents it as the gospel and they really don't know nearly as much as they think they know. Brings on my aggravation when people don't bother to really read what I have said in prior posts (and not just the very first post).

I can be a real bitch at times. Last time I looked in the mirror I did see a human and humans are far from perfect. Besides....he got the PG version of my wrath and doesn't know it. I can be a whole lot more of a bitch than I was here.

The jury is still out on whether I keep the AirSense 11 AutoSet or sell it. I wanted to do more work with the for Her mode but while the setting of 6 for humidity doesn't appear to cause horrible symptoms ....it's not entirely symptom free and when my nose doesn't work right then I tend to be miserable during the day as well as sleep poorly during the night.
So I gotta decide which "evil" is the least annoying "evil".

If I can get off my lazy butt and swap out masks (which means hose cozy as well) today then I plan to try to get back to the Eclipse and see how it does.

BTW....9 1/2 hours of use on the machine last night with humidity set to 6 and while I didn't have a lot of water left over.....The water chamber wasn't dry this morning. Water still well covered the bottom of the chamber.

If I were you, I think I'd be inclined to just go back to the AirCurve 10 and the set up that was making your nose happy with little or no rainout.

And my own water-loving nose wishes yours well as you try to make the AirSense 11 work with that humidifier set to something less than its max while still getting some rainout.

If you have a spot to store the AirSense 11 for a couple of months or so, you could keep the AirSense around for a couple of months and then repeat the experiment for the "For Her" mode once the weather warms up.

Finally, I'll add this just to make your nose a bit envious: My bedroom temperature is being kept at 50-55 degrees this winter due to some construction issues on the house. We have a big down comfort on the bed to keep us warm. I'm still using an unheated hose with the humidity set to 8 on my AirCurve 10 VAuto. By running the hose under the covers and keeping my whole head under the covers, I'm able to minimize the rainout to where it seldom wakes me up.

I keep planning on digging the heated hose out to hook it up; my husband and I had to take the heated hoses off our machines this past summer when we were camping in Arcadia using battery power, and I just haven't gotten around to putting them back on.

Envious indeed. I am pea green with envy.

I have everything except my head under the bed covers but it only takes a tiny bit of rain out to disturb my sleep and my house is probably 10 degrees warmer than your house. It may cool off a bit as our weather cools down more but we had new windows installed a few months back so I am unsure just how cool it will get once it turns off really cold. I know the drafts have stopped. Our winter has been rather mild so far....supposed to get to mid 60s tomorrow but the bottom is going to drop out around New Years.

My only other idea....more bed covers or heavier bed covers but I really wish the heated hose would do a better job.

I have the Eclipse attached now so I will see how that goes tonight. I don't see it changing anything but you never know.
I was surprised to find that the Eclipse (with all else being more or less the same) used about 1/3 less water than the P10 so strange things do happen.

You may be right....I should probably just wait a bit on using the AirSense 11 any more until things really warm up and my chances of rain out reduce with the warm weather.
But I am a stubborn old witch and will probably try it a bit longer and just continue my whining.
I don't really like the added weight from the hose cozies anyway.

Now I have to decide if I want to break one of my own rules...the one about making more than one change in something at a time.
