Preventing rainout in nasal pillows

[OntarioKevin]

Using a Resmed S9 with a Liberty Hybrid mask.

I've gotten it sealing pretty well, pressure is working pretty good at 10.6.

Climate controlled hose, covered in a fleece jacket.

The Resmed S9 uses a temperature setting, and I've tried 67-70 degrees Fahrenheit, all with the same result.

After about four hours, the nasal pillows are so wet from the inside I have to dry them out in order to continue.

I generally breathe thru my mouth, so I'm thinking that there's just not enough airflow thru the nasal pillows and the water vapor just forms and hangs out there.

Any advice?

I'm actually OK to use a lower temperature setting for the humidifier or turn it off altogether - the dry mouth is irritating but not as much as waking up so much!

I don't thing the type of mask will determine rain out. Make sure your machine is below your head. Water cannot travel up hill.

The machine is below the bed.

But of course the moisture in the air travels up the hose, and the moisture in my exhalations is already in the mask.

Maybe I'm mis-using the term "rainout"? In any case what I mean is the nasal pillows become waterlogged.

Kevin.....

For years, I've prevented condensation annoyance in my nasal pillows by inserting a piece of cotton string that acts as a wick. I'm not sure how your mask is actually built....so, I can't tell you how to place the string.

The wick I use is simply cotton string...of the type and thickness of "butcher's string".....something you'd use to tie up a beef roast before cooking. It works perfectly.

The source of your condensation is more than likely coming from exhaled breath......and probably amounts to just a few drops over the course of a night's sleep. I suggest that you set your humidifier on its lowest setting and experiment with a wick (string).

The wick will soak up the few little drops before they can get into your nose to cause discomfort.....and dry out during the day when the mask is not in use.

If you need more info including pictures of how I insert the string into my mask, PM me and include your e-mail address so that I can transmit jpg images.

Did you system come with a "slimline" hose?

Have you tried it?

The air is going to compress as the flow shrinks and the water just can't stay in the air anymore.

If you change tubes, you need to tell the s9 what type you use (but I think it defaults to slimline if it doesn't detect the climate one)

[Sheriff Buford]

Another question: are you using the Climateline hose with your Resmed machine?

If you have a Slimline hose, try using it at the lowest setting, slowly working your way up through the levels until you begin to have water in your pillows. Then back it off a bit. I've had the problem you describe when I run the humidity high but not so much with it lower. I use the Slimline.

Here's a brief piece on rainout that you might find helpful: http://www.betterrestsolutions.com/Why- ... _b_13.html

Locust.....

Your article is a good one. It does a good job of explaining "hose rainout".

It's helpful if one understands that there are two kinds of rainout. The most difficult to combat is the "hose rainout" described in the article you presented.

The second type of rainout is "exhaled breath condensation" and that's the type I think Kevin is fighting.

Both types aggravate us.....and they require different solutions. Each can be conquered more easily if clearly defined and then attacked with the solutions best suited to each type.
