Rain Out Help

[lytepole]

I've had my S9 for over a year. In the last couple months, I've been having a lot of issues with rain out - to the point that I'm waking up because I'm finding inthard to breathe because of water in my mask. I turned my climate line hose down, but I'm still having issues. I'm trying to figure out if I have a hose problem, a machine problem, a setting problem, or if the problem is the extra humidifier we have in the bedroom now. FYI - my humidifier tank is barely changing levels at night now.

Thoughts? Should I change settings more for humidity or should I start testing all of the components to see where the issue is?

Please excuse typos - posting from my phone.

Because of the humidity of the room, your CPAP humidifier does not need to produce much more humidity. Evidently condensation is forming in your hose.
Solutions would be to turn down your CPAP humidity, lower the machine so that it is lower than your mattress...(any water will run downhill back to the machine), get a hose cover, get a hose hanger which will force and excess water back to the humidifier reservoir. There is nothing wrong with your equipment.

What is your room air temperature?
Is your climate line hose covered?
What are your settings for heat and humidity?
How is your tubing and machine set up in relation to your mask (mostly considering heights)?
What problems were you having with the auto setting that led you to choose custom climate settings?

It's possible a cover would resolve the problem, or the climateline is damaged, or that the settings you have are simply going to cause rainout and you need to rearrange the machine and tubing so any rainout is drained back into the humidifier, rather than collecting and blocking the tube.

Ever since I changed to a ResMed ClimateLine Heated hose, the rain out has stopped. I have my hose hanging high on my back board. I don't have a hose cover, and I sleep in a cold room (gets down to 59 deg).

Is your machine recognizing ClimateLine?

I've been trying different things the last couple nights with no relief. Last night I was so frustrated I removed my hose and mask and hung them up in the hope they would drip dry out - they were all wet in the morning. The water droplets were throughout the whole hose including my mask hose - going up to the hose holder and back down.

Answers to some questions:
What is your room air temperature? The temp is set to 65 at night.
Is your climate line hose covered? No

What are your settings for heat and humidity? I used to be. At 4 and 85 degrees with no problems. Most recently, I was at 1.5 and 80 and was still experiencing rain out. Last night I set it to 0 and 80 degrees - still had water droplets all through my hose.

How is your tubing and machine set up in relation to your mask (mostly considering heights)? My machine in on the night stand about the same level as my bed, then I have a hose holder up about 3 feet over my head so the hose come up and back down again.

What problems were you having with the auto setting that led you to choose custom climate settings? I have very bad sinus issues and wanted more humidity. I have been operating successfully on these settings for almost a year.

Is your machine recognizing ClimateLine? It appears to be - I detached and reattached the hose and the symbols changed. I can adjust the climate line hose settings as well.

Since you hade no problems at 4 and 85 degrees, I would try turning the tube temperature up from the 80 degrees you have it on and maybe even putting a hose cover on.

"Rainout" is simply a matter of physics.
If warm, humid air (water vapor) is getting carried out of the heated humidifier, going through a cold(er) hose, it's going to condense back into liquid form. So, either the HH settings need to be lowered (or turned off) or the surrounding air needs to be warmer so it doesn't condense back into liquid form (room air temp, heated hose or routed under the bed covers).

Quick update - we turned down the room humidifier and I had one full glorious night of sleep. Last night I had ran out again but it was only in the tube between my mask to the heated climate line tube.

Should I try a hose cover over my mask tubing or do you think I need to rearrange and run my tubing up under my covers towards my face?

I think you want to turn down the setting on your cpap humidifier as well. If that still doesn't help, then I'd invest in the hose cover.

A suggestion for trying out to see if a hose cover would help.......... wrap a thin towel around the hose and secure it with elastics.
If you are handy with a sewing machine make a hose cover out of fleece. Just sew a long tube and slide it over your hose. I small hint for anyone trying to get a tube over your hose end... just place a baggie over the rubber hose end and the tube will slide on very nicely. Hose covers can be made out of anything that keeps the hose warmer in a cold room...... tube socks, towel, you can knit one too, fleece, flannel.....................
good luck

If the heated humidifier is off, and you are still getting rain-out, there is probably something not right. You can start diagnosing the problem by probing the heated hose (when not connected) with an ohm meter.

I posted the resistance info for the climate-line air a while ago. Yours will be the same, but I don't know which pin is which on your hose. However, there are only 3 so it should be pretty easy to guess.

"With the connector pointed down, and you facing the gold contacts, the following is the pinout:

Left Pin: Temperature Sensor
Middle Pin: Common (ground)
Right Pin: Heater Connection

Left to Middle is about 12 kOhm at about 70 degrees F. I don't know the exact transducer model, but looking up standard transducers, this will be about 20 kOhm at 50 degrees F,8 kOhm at 86 degrees F, 10 Kohm at 77 degrees F and 5 kOhm at 100 degrees F. If the values match approximately here, then the the temperature sensor and wires are good.

Right to Middle is 10 Ohm. This will also vary with temperature a little, but it is unlikely to vary much.

An open circuit on either the Left to middle or right to middle means that the connector is broken. If the problem is intermittent, you can try flexing the connector a little while taking the measurements to see if the something opens up."

If your room humidifier is the cause of the rainout in your hose, it was set way to high, whether or not the heated hose was actually heating. I wouldn't be surprised if you have some dampness and possibly mold in the colder corners of your room.
