It's raining again

I am convinced my rainout is due to my breathing out and the warmer exhaled air forming condensation in the mask. I had drops in my mask, but nothing in the hose this morning. I am hopeing that the aussie hose will warm the air enough to equalize the temperatures? The drops run down and make me think my nose is running

Melissa,

I would direct you to this post, but I'm guessing it was from last winter, so I'm not sure I could find it, but someone posted that you need to cover ALL exposed tubing. That would mean the short connector tubing that you showed in your picture. I also remember the person posting (was using a Swift) also covered the barrel for the nasal pillows too. It helped that person tremendously by covering not just the long tubing, but anything exposed (obviously not the air vents though)

I just can't figure this out. I took a nap, b/c of course I'm exhausted being the mask went off my face @ 2am. It was 68 in my house and I slept for an hour to find that there droplets again in my mask. That certainly is not cold. Plus I had wrapped all exposed tubing in my mask prior to the nap. One more thought, could it have something to do with the type of tube I'm using? When I got this machine, I used the tube it came with. But again, I didn't have rain out with my other machine and tube. I still have the tube, I could try, but wondering if anyone knows this to be a reason. Or are all tubes the same?

One more question. If I turn the humidifier off tonight, there should be no possible way of rainout, correct? I have to work tomorrow and can't deal with this again tonight.

Melissa,

That is weird, 68 is not what I would consider cold either. does your hose hang up and over your bedboard, or do you just let it fall to the floor? I assume your machine is slightly lower than your bed or on the floor? I saw you had responded to those other tips earlier.

I didn't get rainout last night, and living in Mass, i'm sure the temp is similar to NY last night. My thermostat read 62 this morning. But I also have an ultra mirage full face mask that I was using. I had my humidifier on 2 last nite. My machine is on a small shelf that is a lot lower than my bed and my hose goes down to the floor so maybe with gravity, that helps any condensation drip back into the hose and towards the humidifier. I also notice that if I use a nasal pillow type mask I have more of a problem with rainout than full face mask.

As far as I know the insides of the tubes are the same except the Aussie hose has heating coils.

I hope someone else can offer some advice, I'm pure out of it. Try just filling your humidifier with distilled and don't turn ON the humidifier just use it as 'passover' tonight until someone else can shed some light on your problem.

I had no rainout on 0, but got very stuffy My rainout has occured even with the tube sock covering at 78 degrees! My unit is below bed level and the hose does not hang over the headboard.

Thanks Suzy..I thought my machine was low enough below my head, but maybe I can lower it more tonight. I have the hose go up from the machine to a hook on th wall above my head and then it comes back down to me and my mask.

Geesh Melissa,
Perhaps we have to have a minor in meteorological science to be able to figure out the proper conditions in our bedroom to avoid rainout.

I have even heard from some members that even with the Aussie hose they still need to use a cover with that. Maybe its not just a temperature thing but if the surrounding air is cooler than the air we breathe out and if the humidity surrounding the tube is less than condensation forms?

You can still use the hook on your wall, (otherwise you might tangle yourself up and that would be a whole other mess!) but try maybe lowering the hook so its not as high up on the wall?

Good luck tonite keep us posted. Maybe the next invention to come along could be mini fans inside our masks to dry any condensation before it gets us!

Oh, great, I would be one of those that even the aussie hose doesn't help, knowing my luck! The part about lowering the hook, is the theory behind that about not creating such a steep incline and decline? I'm not trying to read too much into this, but.....oh who am I kidding, yes I am!!

snoozie_suzy · Post by **snoozie_suzy** » Sun Oct 08, 2006 7:22 pm

Yes, Melissa, the thought is to not create as steep of an incline so that hopefully if condensation does occur it will hopefully not all go into your mask but instead back down the tube.

I wouldn't think you have to put the machine on the floor per se, I have my bed on risers, so its quite a bit higher than my nightstand. so therefore my machine is LOWER than my bed, I also use a scrunchie on the wall with my tube strung thru it, but the scrunchie is just a few inches up the wall, not very steep at all (I don't have a headboard). On nights that I know it is going to be frigid, I sometimes lower the heat to 1 on the humidifier or even use passover.

Try a couple of these things tonite to see if they make any difference. I sure hope they do and you get some better sleep.

Just wondering--Is there any possibility that this excess rainout has anything to do with the M series machines?? I run my humidifier at around 1 or 2 and have even had it up as high as 3 with no rainout...and it is cold in my house at night--my landlady who lives on the main floor of our duplex controls the heat--and believe me--we call her the heat nazi.
I do have a snuggle cover--but that's it. What seems really unusual is that there was even condensation on the outside of your hose with the cover on Melissa.

If there is moisture on the outside of the hose it means there is too much humidity in the room. Even though the air may feel dry, moisture is coming from somewhere. I would try a dehumidifier and see how much water it collects in a day. You might be surprized.

The only problem Brenda, with cutting down on humidification in the room this time of year, is people with sinus problems (which I'm guessing she might have from her previous posts on sinus irrigations) is that it can cause havoc on the sinuses having the room too dry. So it might solve one problem (rainout) to cause another (sinus pain/dryness). I see your idea though about the condensation on the outside of the tube though.

Could it have anything to do with the fact that my range is 4-20 and I'm starting out so low?

absolutely! if your Min. pressure is too low it will cause you to rebreathe too much your exhaled air, the exhaled air contains moisture and warmth from your lungs. Just like going outside in the very cold air, same thing can happen.

If you increase your bottom pressure from 4.0cm to 5.0cm or even 6.0cm, the incoming air will be more refreshed and flush out some of the moisture that is causing rainout. 4.0cm for most interfaces isn't enough for proper CO2 washout.

I'm sorry if I said anywhere that there was condensation on the outside of my tubing, b/c there isn't. Always on the inside. I slept with the machine alot lower, the tube not so high and the humidity off. So of course no rainout , but boy are my nares sore!!! The only other thing that is different other than the machine is my pressure setting, so I think snoredog might be onto something. Maybe a little something to do with c-flex as well? Not all this amount of pressure of 10 being flushed out of my exhale port?
