Rainout despite heated hose -- aargh!

[needzzzzs]

Like much of the continental US, we were in the deep freeze the last couple of days, weather-wise, and the heat pump in my house could not keep the air temp as high as we usually keep it.

Last night I woke up a couple of hours into sleep with rainout, despite having a heated hose. I did not have a second heated hose available for my machine, so spent the night in my recliner.

Aside from having a second backup hose, what could I do to prevent this happening again? A hose cover (safe over a heated hose)? The extreme cold is an anomaly here, but could potentially happen any time.

Words of wisdom, please.

Thanks,

Debbie

I have a heated hose and it stopped any rainout I had . . .until I bought a hose cover. It appears that the cover insulates the hose so well that condensation doesn't form until it reaches my nose. This condition wakes me up with a tickling sensation where the nasal pillows contact my nose. This has been occurring ever since I installed the hose cover. It took me awhile to connect the correlation of the rainout and using the hose cover. After experimenting with moisture levels and heat settings, I finally removed it in the middle of the night and the rainout ceased. I like those hose covers too. I guess I'll have to find another use for them.

I'm new to all this but experienced close to the same thing last week when the temperature dropped to around -5 outside. The rainout i experienced wasn't in the heated hose itself... it was in the unheated section of hose that comes attached to the AirFit P10 nasal pillow mask. What worked for me was dropping the humidity level and raising the hose temperature. After reading up on it in the manual i've since changed the machine's climate control setting from manual to auto... hasn't happened since. I agree that a hose cover more than likely isn't needed on a heated hose... might not be a bad idea on the unheated section attached to the mask though.

Unfortunately the Nuance Pro comes with about 18" of unheated mask hose. My bedroom is COLD, sometimes below 50, and rarely above 60. The last several nights I woke up to the sound of gurgling water in the mask and hose. I shake the water out and go back to sleep. I often dump cold water on myself or on the bed in the process. I have tried several different ways of hanging the hose. Nothing seems to work. No clue why they need such a long mask hose or why it can't be heated.

I have not tried a hose cover.

Oddly, water running back into my nose does not seem to bother me as much as the noise.

Both the Nuance (Pro) and the P10 have the hose pigtail. Actually in retrospect, I believe most nasal pillows come with a pigtail. I am digressing!

I tried the normal length hose cover(6') that didn't include the pigtail portion and thought that this might have been the problem. I then got an 8' cover so I could include the pigtail. This just moved the point where the condensation occurs. Also I live in the south and am not experiencing the drastic temperatures that the rest of the nation is going through. I also have central humidifiers that maintain my house at 35% to 40% humidity, as well as, I keep the temperature at 70 degrees at night.

I think you have solved the problem, Offroad Toy, and I have the same mask you do (despite my equipment listing...I have forgotten how to change my equipment) -- the Airfit P10 nasal pillows. Yes, it's clearly the unheated part of the hose that's causing the problem. I will have to read the book about how to raise the hose temp (if I can with my machine), but I can certainly drop the humidity level easily.

Thanks!

And position the machine/humidifier lower than yourself when lying down - water won't run uphill.

I have the machine lower than the bed and that does help. The problem is that if I leave enough slack in the unheated pig-tail hose to move around, it forms a trap with one section lower than the rest.
