How to stop rainout?

laurie2025 · Post by **laurie2025** » Sun Dec 03, 2006 4:38 pm

I just switched over from a Swift to the Everest Aura Twilight NP, and last night experienced rainout. I have a heated hose and a hose cover. I've been running my humidity setting at 3, I was having a lot of dry throat with it set and 2 and 1. I can see the moisture condensation is at the front part of the mask, the soft tube that holds the pillows and about 2" of the main hose that comes down the front to hook up with the soft tube.
It is very cold here (Chicago suburbs) and we lower our heat at night to about 68.
I have not deconstructed my mask, as it is working well for me out of the box.
Any ideas on how to combat condensation?
Thanks.

I know this isn't the same thread, but for all you parrot lovers; I have a Sun Conure and a Black Masked Lovebird.

a different mask can increase/change rainout do to its CO2 washout characteristics. The more of your exhaled air the mask retains the more moisture that can build up in the mask and contribute to rainout.

When it is raining or snowing outside you are probably at 100% humidity, cpap machine can concentrate that moisture.

You have to turn the heat portion on the humidifier to its lowest position or off. It will still deliver moisture even when off as long as water is in the tank.

Setting the machine much lower than you bed or on the floor can also help as the water won't run up hill, so it will drain back in the tank. If you have the M series elbow on the back be careful that water can leak from the elbow where it swivels.

I've been having hassles with dry throat the past couple of days - however every time I increase the humidity, I get rainout, which, to me, is far more annoying than the dry throat. The thing is, I have a heated hose, so in theory, I shouldn't be having the rainout issues, especially if I increase the temp of the hose (at least, that's as far as I understand it).

As an experiment, last night I increased the humidity on my F&P HC608 to 3.5 (up from its usual 2) and completely switched off the heated hose. I was fully expecting to be woken up with rainout at some stage (although with my Comfortgel, it's usually a fine spray of moisture that escapes the mask edges where the hard plastic bit clips on to the soft cushion. To my surprise, I had no issues last night. I actually had a decent night's sleep. I noticed that I did have condensation in my mask this morning, but it was nowhere near as bad as I've had it before. My throat was still mildly dry (again, much better than before), so I'll try up the humidifier to 4.5 tonight and see how it goes.

For what it's worth, it's summer here at the moment and the evening temps are around 20C or so (I guess).

For me the only answer was the Aussie Heated Hose from sleepzone dot au.

Its a bit over 100 USD (with shipping). Your insurance probably won't buy it for you. However, it wouldn't hurt to try.

I already have the heated hose and a comfortsleeve cover on top of that.
It's 15 degrees at the moment here and I did have rainout again last night, had to take the mask off about 4:00 a.m.
Any ideas appreciated. Thanks.

Laurie,

Did you have your heated humidifier turned on? If so, I'd try turning it off, and allowing the Aussie to heat the (passover-humidified) AIR. ????

Thanks, I will give that a try.

Laurie,

Although I can be counted among the lucky ones who has not experienced this problem, I read somewhere that it helps if you keep your machine at a lower level than the head, either on the floor or a low stool. This way any condensation will flow down to the humidifier instead of your nose. I

I hope this helps. Good luck,

David

I have my machine (not an M series) about 10" off the floor, well below my bed height. I am going to run the machine tonight with the humidifier heat off. I did that before but I got the driest throat, and had to put it up to 3. (I tape so there is no mouth breathing).
My aussie hose isn't hot it's just pleasantly warm.
Thanks!
Laurie
