S9 climateline hose

[Marke]

Good morning,
I just got my climateline hose, (it was back ordered for 2 months)
and 1st night results at 75% Humidity my ahi was 3.2 Mouth felt dry
my 2nd night results at 80% Humidity my ahi was 6.1 Mouth felt dry
I have it set to auto, I live in Cleveland, Ohio and the last 2 nights were cool,(windows open and my unit sits right next
to an open window, so breeze runs right over it.) I noticed this morning that it is barely using any water, I filled tank 2 nights ago
and from the looks of it I won't even need to add water.
Should I go into manual mode to play with the settings, or go back to standard tube for the summer months and use climatelimeline for fall and winter.
My ahi with standard tube has been @ 0.0. to max of 2.5, to 3.0 (Thats for the last 2 months, Got my S9 on 4-2-10)
Any input would help, other than that Therapy seems to going well.
Thanks,
Marke

I would say that humidity of the air in Cleveland at this time is already pretty high.
When set to Climate Control... you only set temp...

As example I use S9 set at 72 Deg Climate Control but in A/C set at 70-71 Deg overnight. I fill every 3 days... no dryness for me.

You have to experiment.

Have had similar problems with dryness that have caused me to wake up during the night. To deal with this I have set the humidity control on manual and have lowered the temperature to below 70 degrees.

My theory is that the process of heating the air in the hose reduces the relative humidity. When there is plenty of humidity in the air in the hose this can prevent rain out but when the temperature is too high or when the humidifier is not capable of fully humidifying the air the relative humidity at your nose is too low thus resulting in dryness.

Just as an aside: you should probably ump your 2-day old water, rinse your tank, and refill with fresh water.

I think you need to revise your theory... I didn't really understand...
the heated hose provides 80% relative humidity based on sensors in the hose including right near the mask.
the heating allows (as all heated air does) to carry more water... not lower it.

But, certainly if you want cooler air and higher humidity... as you said lower the temp and raise the humidity level to 4 or 4.5...

The dryness that I noted was when the humidity level was set to 6.0.

Agreed heating the hose allows the air in the hose to carry more air. The problem is that when it does this it lowers the relative humidity. If the relative humidity in the hose is low enough the air in the hose will absorb the moisture in the nose and mouth thus leading to dryness.

Heating the hose works as long as the relative humidity out of the humidifier is high and the temperature in the hose is not too much greater than the temperature of the air entering the hose. In other situations it only agrevates the problem.

I've read that several times...
Let me say this and you see if it agrees with what you have here.

Your CPAP, Hose and Mask form one self-contained unit... there are no openings (except to accept an inlet) to change anything but some heat loss can happen.
Think of that unit as a separate room in your house that has no opening except to suck air in.
This room has a heater that you can control and some water that you can add to the air by heating it.
The air in the room will hold water in the air depending on the temperature... if the room gets cooler... water droplets will form on the coolest part (Hose, Mask)
If the moistened air makes it to your nose and throat... then some of it is supposed to stay there.
Unfortunately some moistened and warm air will come back out of your nose and overload your 100% humidified air already there...

That will overload it with moisture along with your warm breath hitting the mask and condensing... droplets form and rainout happens.
That's why ResMed guarantees no rainout with 80% humidity.
There are no rules except those Natural Laws that you have to follow.
That's why you have to experiment and nobody has the "right" answer.

That's my best shot... if it doesn't work for you... I'm guessing you'll have some reading to do.

My initial posting I typed the wrong info.
1st night settings were at 75 degrees (Not humidity), my ahi was 3.2 Mouth felt dry
and my 2nd night settings were at 80 degrees and my ahi was 6.1 Mouth felt dry
Last night I set it at 70 degrees and had an ahi of 6.0 and also dryness
I believe this weekend I will switch to manual mode and truy some different settings
to get more moisture, if not I'll be switching back to my standard tube until I get this figured out
As I said in my first post I haven't had these High ahi numbers since I first started therapy.
Tonight I will upload my data and look at my nightly graphs and see whats going on.

Thanks,
Marke

Dryness can also stem from leaks... take a look at your detailed view.

I too, got my climate hose yesterday. Would it be okay to put a wrap over the hose? 1 for looks, 2 so it will move as I move? Thanks

I had experienced the same issues with my resperonics unit when I had it set to first 2.0, then to 3.0, then I tried 4.0, this was much better but often caused rainout. I was really happy when I read about the climate-line for the s9. I have been using this machine for a week now. When I picked up my s9, my rrt suggested I set the temperature to 80 degrees, tried this for one night, moved up to 85 degrees, this was a lot better, the last two nights I have been @ 86 degrees my AHI has dropped from 2.1 down to 0.19 and the dryness is almost completely gone.

Hotter air can hold more moisture, this worked for me, I hope it helps you.

ResMed does make a tubing wrap specifically for the S9 ClimateLine and SlimLine hoses. It is made of fleece fabric on the outside, lined with nylon material inside. It's out of stock right now at cpap.com, but here's the info: https://www.cpap.com/productpage/resmed ... -wrap.html.

Since the ClimateLine is heated, I would be careful with hose wraps that may be too thick. I believe it's recommended that the heated hose not be used under blankets (probably to limit liability in case it were to overheat?), so I think the same caution would apply with a thick hose cover.

If anyone knows the answer to this for sure, I'd like to know. I would like to cover the ClimateLine/SlimLine hoses, but ResMed's blue cover doesn't happen to go with my decor.

If you are concerned about the color of the hose covering you obviously do not have a compelling medical reason for the hose cover.

There's nothing wrong with wanting a hose cover that's both functional and eye-pleasing.

I'm already thinking I might not want a ClimateLine hose since I can't put a cover on it. Or at least probably can't, I think I read it somewhere.
The CL hose seems to be making treatment more confusing, instead of adding to comfort. I've been really happy with my homemade cover on a regular hose, and I'm close to deciding not to order a fancier hose.
In the meantime, you guys keep trying. You may have a breakthrough that makes it simpler for the rest of us!
