Rainout with Sleepweaver Elan

[flyingwithoutwings]

I was reading Pugsy's post on rainout at the mask and she quoted Chunkyfrog saying she's never experienced rainout with the sleepweaver. Last nite I experienced rainout for the first time and I was wearing the Sleepweaver Elan. I'm thinking of getting a cozy for the short tube but I don't think there's a way to insulate the mask itself.

I have my heated tube at max. Any suggestions?

Sorry to hear that. I may be sleeping in a warmer room.

I also use the Élan. I have always used a heated tube. Currently using PRS1 Auto ASV and my humidifier is dry every morning but I have never experienced rainout.
I do keep the bedroom about 68' so that may make a difference for you polar bears.

Last night the temperature dropped and my room was 68 degrees (nice!) but my humidifier & tube were on max.

Short hose cozy might help..wouldn't hurt. You can make a quick homemade one with a small towel wrapped around it or hand cloth. Secure with rubber band or scotch tape.

Will most people experience rainout sooner or later? I was told by my doctor (pulmonologist) to put the machine at head level or slightly above, but have read here or on another forum that the machine should be below head level to prevent rainout. This is something I had never heard of before getting on any support forum. By the way, my wife and I like to sleep in a cooler room in the winter.

I made a wrap and secured it with velcro but I was getting too many leaks so I used old faithful Swift FX. I'm just going to order a cozy and hope that works.

Not everyone experiences it.
It's caused by a perfect storm set of various circumstances.

Placing the machine lower than the mattress works well for helping reduce rain out in the hose because it allows gravity to help direct the condensation down towards the humidifier and if it stays out of the hose...no noise and believe me....that little tiny bit of water in the hose creates lots of noise.

Now for condensation at just the mask itself...machine placement doesn't always help because often the mask hose has some sort of uphill direction before the long hose gravity can help. Just look at your mask in bed...any part of it have to go uphill? Water doesn't run uphill so great.

Condensation at the mask level is that perfect storm of situations.
Room air is cooler.
Humidity being delivered from the machine and also exhaled from out own breath...cools at the mask level
and condensation occurs.
This can happen even if a person doesn't even use a humidifier...so just from the moisture in our own exhaled breath if the conditions are right.

I turned over this morning and a single little drop of condensation rolled out of one of the vent holes on my mask and onto my cheek.
This is despite using the PR S1 heated hose (set to 4 so I guess I need to try 5 which is max heat) and a little barrel cozy (admit it doesn't fit so great since it was made for a different barrel). It's always been a winter battle for me because my nose likes max humidity settings.
I will take a single drop gently rolling out onto my cheek over a cold shower or the noise of rainout over the symptoms my nose gets if it gets to dry. I like a really cold bedroom...I give it a perfect storm of conditions ripe for condensation to form.
I haven't yet added a short hose cozy because of the added weight from the hose cozy but if this is all I get...I probably won't do much but if it gets worse then I may add some more insulation to the short hose in hopes of keeping that warmer air going to the mask just a little warmer and lessen the cooling that releases the moisture.

Some people just don't have the condensation form...the perfect storm of conditions is not quite "perfect" for the condensation.
If it does we deal with it. If it doesn't we are lucky. It's annoying but it won't hurt you. If it wakes you up..then it needs to be dealt with because it disturbs sleep.

Thanks for the reply. If I place my machine at a level slightly (6-8 inches) above my head and then used the device that holds the tubing above me, will that prevent any condensation to my mask?

Condensation in the mask itself can come from the moisture in our own exhaled breath condensing due to room air temps.
Even putting the machine directly on the floor and routing the hose so that it never has to go uphill isn't a guarantee that no rain out at mask level happen.

Condensation in the hose and in the mask...are/can be 2 separate problems...just depends on all those factors I talked about.
The level of the machine or hose...helps by using gravity to help drain the condensation in the hose downwards.
It helps with where the moisture goes once it has formed...doesn't help prevent it from occurring at all.
Mask condensation isn't always helped by machine or hose placement. It can help but not eliminate.

If your machine and hose generally go upwards...gravity can't help you at all.

So I am all about preventing the condensation in the first place and then I don't have to worry about where the water wants to run.
Then I can put my machine and hose wherever I want to.
