Help - Rainout w/ a Heated Tube - Brahmabull - 12-23-2020

I have a resmed airsense 10 and a heated tube.  My house temp this time of year is 70 deg F.  I am having problems with rainout even though I have  a heated tube. Any ideas on what to do to prevent rainout?

I would recommend a hose cover to insulate the line. I have one on my ResMed heated hose and have had temps in the house as low as 65˚F or so with no hint of rainout. And a lot of water gets used up from the humidifier tank. So I'm sure the RH inside the tube is quite high and would be prone to rainout if not covered.

Also, the soft tube covers drastically deaden noise whenever the tube hits the headboard or anything else. Don't need anything fancy or expensive, just whatever color the wife finds pleasing.

Lastly, the ResMed heated hose is a bit longer than the standard hose. So about 6 to 8 inches of hose is uncovered on mine. I keep that uncovered portion towards the machine end.

Not sure how you have your machine placed, but I have mine on a bedside stand that is the same height as the mattress. 

The hose runs up (70+ degree incline or so) to the top of our bed's headboard to a hose hanger / holder, then back down to my FF mask. No way can it have rain out like that. 

I too, use a hose cover and it's well worth the very affordable cost. Mine was like $7.00 or so, is black and fleece.

I look at this another way: if you have condensation, it means the air in your tube is over-saturated with moisture.  I don't know what your current hose temp is, or even if it actually gets close to that, covered or not.  But if its above 24 deg C, and your humidity setting is under 4, it still may be too much for the rest of the room's air, and remember where you machine gets it.

I understand that you may have settled on settings that have you secure, comfortable, and getting good sleep, especially if the settings now yield a distinct improvement over your earliest settings.  But, have you tried reducing the humidity level AND raising the tube temp?  Or, why have you limited the tube temp to whatever setting it currently has?  Maybe you could raise it two points, or three....?  Maybe seasonal changes inside your sleeping space mean that you should alter your settings seasonally, and NOT expect to suffer for it.

Currently my tube temp is set at 80 deg F and humidifier set to 3. You think I should increase my tube temp? Room air temp is 69 to 71 F

BTW...
With my ResMed ASV machine, I set the heated hose to "Auto". Seems to be fine for what I need.

I had it on auto for a long time. I guess I could try setting hose back to auto and keep humidifier setting at 3 or less.

Look, my machine is set to manual with humidity 4 and tube temperature at 80. The only possible difference is I use a fleece tube cover, and live in a colder climate where condensation should be worse.  Get a tube cover. It's cheap and more comfortable.
