I believe it is called rainout

Been on APAP for close to 2 years now, last night I had something occur that was new for me. Having a great nights sleep now that I have finally given in to taping my mouth shut (some of you would call it my BIG mouth) Middle of the night I hear a clicking sound and it takes a while but finally realize it is a buildup of water in a low point in my hose (heated hose). It was very cold last night and we had the heater off and the windows open (huge comforter, great sleeping weather). I am wondering if my heated hose has stopped working and how I would determine this.

I have a hose cover I bought from Metsfan and it is not on right now, I will put it back on tonight and see if that helps - any thoughts.

As an afterthought, I believe the water that came out of my hose was cold, maybe an indication my hose is not heating?

Be sure the CPAP is lower than your mattress. Water should drain back to humidifier

The CPAP is lower but I have the hose going up about 18 inches where it is supported, then back down which I thought would take care of any water.

Make sure that your mask vents are clear and working as intended. The only time I had a rainout problem with my AirFit P10 with heated hose was when the very tiny exhaust vents had become clogged over time. When you are wearing the mask with the machine on, you should be able to feel with your fingers some amount of air coming out of the exhaust port at all times. In my case, it was completely clogged and a quick soak in Dawn and then blowing compressed air from a can through the vents cleaned it out and completely stopped the rainout.

You should be able to tell if the heated hose is working by seeing if the surface temperature if the hose is warmer than the room. Also, it's possible that you're overfilling the water chamber, and "got away with it" when it was warmer.

also, it's possible you've no idea what you're babbling about.

What temperature do you have your hose set to? While it is possible that the heating coils have stopped heating it is also possible that the temperature you have selected simply couldn't overcome the cooler ambient air temperature.

I would sometimes get condensation in the short hose (from the long heated hose to the actual mask) or mask when I didn't have the hose air temp warm enough to compensate for the much colder bedroom ambient temperature when I would do what you did....no heater yet in the house and colder air temps and just use the bed covers. Great sleeping weather though. The heated hose was working but just not warm enough to keep the condensation from happening.
I normally use hose air temp set to low 60s with my S9 in the summer but in the winter I have to crank it up to the 80s to prevent the condensation.

My hose was set to 78 and my humidity was set to 6. I have changed the humidity level to 4 and the hose temp to 80. I just let the hose run wide open for about 10 minutes (still had a lot of water in it), checked the ambient air temp with an instant read thermometer and it is currently 73; I checked the air coming out the tube and it was 78.7. I was actually quite impressed that it could raise the temp that much in 6 feet but I wonder what it would be when the room is in the low 60s. I think I will clean my hose (has been a couple months, at least ) dry it and put the cover back on it and see what happens tonight.

Thanks to all for the tips.

could it be the "Humidifier: REMstar Heated Humidifier" you have in your profile?

maybe it should be called "rain-in"?
"rain-in" in da hose

Rain in, I get it and quite fitting. I don't believe it is the humidifier, all it does is warm the water and air passes over it and even on 6 it is not quite empty in the morning. I think it was just the cold air hitting the warm humid (inside) tube and condensing the water.

Sometimes the temperature line between condensation or not is a fine line. Like maybe just a degree or two more will prevent the air from releasing the moisture. So the hose cozy or a little more hose air temp may be all that is needed. For myself...I have to have the moisture so reducing the humidity really isn't a way I want to go so that's why I will crank up the heat on the hose air during the winter months.

I also will add a cozy to the short hose sometimes so that I have less chance of moisture happening in the nasal pillows.
I also got one of Metsfan knitted hose cozies last winter...plus one for the short hose. They help a lot.

You might just remove the humidifier choice from your equipment...the Remstar part of it threw me for a loop until I saw the machine information. Since the machine choice includes humidifier in the name there is no need for a humidifier choice in your equipment profile.

Three weeks ago - you missed it?!

It turns out that if your vent becomes completely clogged you keep opening your mouth and mouth breathing. That was the clue that something wasn't right.

Nothing else had changed, but the perception was of one not getting enough air. In fact, it's a buildup of carbon-dioxide. Cleaning the vents lead to easy, normal breathing again.
