9,000,000th question about RAINOUT

[onthefreeway]

Hi folks -
Just a quick question here.

For some reason, this past week I've started to experience "rainout" again - haven't noticed any in the last month, but now in the morning a few drops are forming in my nasal pillow and waking me up. Room temp has been steady (about 72), as has the outdoor temp (cooler - maybe 65).

I lowered the humidifier temp from 78 degrees to 74, but it hasn't helped (I always get confused on this - should I go higher?). I also use a hose hanger. So I am thinking that this is indeed caused by my own breath. Is there any way to control it without using a barrel cozy? I have the Swift FX for now but I keep thinking I'll find the perfect mask one day, so I don't want to invest in lots of chachkis ...but I do want to be comfortable, so I will if it can help.

Also - I have the heated ClimateLine. Am I correct to assume that a hose cover would be redundant? Or might it also help?

Thanks for your insights...

I've used the climateline since I received it and haven't had a lick of rainout in any season or location since. If all other things have remained constant and you are using the climateline hose and it's raining out when it wasn't before, it makes me wonder if the hose heating element has stopped working properly. Is the rainout in the hose as well as the mask, or just the mask?

Lately, the AC has been on the fritz, and we have had to use a window fan to pull cool air into the bedroom so we can sleep.
The intake window is right over my head, and the breeze hits my short hose, creating much moistness.
I suppose that into each life some rainout must fall. Since it hardly bothers me, I'd be happy to take yours;
The swamp was very dry last year.

Don't really have any insight here, but my experience the past three nights has been a few drops in my nasal pillows. Could this be that I have been 'stuffy' the past few days? Don't know, but something I thought I would throw out. (Each morning, when I get up, I remove the water from the humidifier and turn on the 'Mask Fit' to blow out any moisture in the hose─have the ClimateLine with a 'comfortable' soft cover, which is nicer to sleep with than the uncovered plastic hose─the 'Mask Fit' routine runs 2 or 3 minutes, then automatically turns off. Am not getting any water drops doing this, like I get when I do this after washing and draining the hose.)

I'm pretty sure the rainout is just in the mask, but I will check again tomorrow to see if there's anything going on in the hose.
Also, it's good to know that others have used hose covers over the ClimateLIne, so thanks for that. I thought maybe that would make the hose TOO warm, and I'd somehow set the bed on fire . I'll also check the "mask fit" blow out - although it kind of freaks me out to hear all that whooshing for 3 minutes straight!

Thanks again!

I turn it on as I'm leaving the room. It shuts itself off automatically; it's either 2 or 3 minutes, never really timed it. (Remember to first take out the water container.)

Hello onthefreeway,

All these ideas sound like they could be the culprit. You might also consider the age of your mask and pillows. I have had customers who have used the Swift Fx mask to the point where the back velcro strap has lost its elasticity. When the mask/pillows wear they don't stay in place as well and cause little leaks. The heater tries to compensate for the extra air loss and in many cases this results in rainout.

Hope that helps.

ResMed recommends that you do NOT use a hose cover with the ClimateLine, because it will make the hose too warm.

But, I doubt you would set the bed on fire.
The heating element cuts off automatically if the temperature gets above a certain temperature.

I disagree with ResMed, the hose temperature is adjustable. Having used this cover from the beginning, I have had no problems with hoses, temperature, heat, humidity, noise, pressure─just masks.

I've been using the CL hose for three years with a hose cover I made myself summer and winter. Climate control is set to Auto/80degrees continually. As Tipiford points out, plastic ribbed tubing is not exactly sleep-friendly when it's in contact with your skin, eh?

... (Each morning, when I get up, I remove the water from the humidifier and turn on the 'Mask Fit' to blow out any moisture in the hose─have the ClimateLine with a 'comfortable' soft cover, which is nicer to sleep with than the uncovered plastic hose─the 'Mask Fit' routine runs 2 or 3 minutes, then automatically turns off.

Removing the extra water from your hose using the Mask Fit feature in the morning may be unnecessary. When you click the power button in the morning to turn off flow, or even you get up to turn off the light, etc., the S9 automatically continues sending air out at a much lower pressure to remove extra moisture from the hose and rapidly cool down the water tank. You can test it by removing the mask from the end of the hose. Gently place your thumb over the hose end and allow some of the air to spray you in the face. It's so quiet and at such a low pressure that most of us don't even know it's happening. It's just another reason why I like the S9.
