Dialing in comfort with humidity and heater hose?

USMCVet · Post by **USMCVet** » Mon Dec 27, 2021 12:07 pm

Was wondering if there are any tips or suggestions on dialing in comfort.

Recently bought a airsense 10 autoset with 300 hours on it. I also have the climate line hose.

The problem I had with dreamstation and now airsense 10 is that I either have rainout but otherwise comfortable or no rainout and my nose is dry and burns so I can sleep.

I've never been able to dial in the right settings to prevent rainout and keep nose from drying out.

Does anyone have a process that works well for them to dial things in?

Some basic questions…

What is the humidity in the room you use your CPAP?
Room temperature?
What do you have the humidity and hose temperature set to?
When you use the CPAP does the hose feel a bit warm?

I had the same machine and had everything set to auto, which gave me an humidity setting of 4 and hose temp of 81F. I keep my room humidity around 50% and sleep temp is about 66F, and have never had a rainout problem.

Room temperature is about 67 degrees Fahrenheit. Room RH is about 40 ish%.

Ive tried machine with hose temp being controlled automatically with humidity set to 4 and also whatever the max setting is. Both times woke up with really dry nose that burned.

Ive also tried setting hose temp to 67 with humidity at 5 and still had dry nose.

I've had humidity at 5 and hose temp at 60 and also at 63 and I didn't have dry nose but kept hearing the gurgling in hose and got some moisture in mask.

I think your hose temp setting is way too low. I set mine at 82 degrees, even though my bedroom is cool like yours. For my ResMed I find that if I set the humidity level at 3 the water does not run out on me, thus allowing my nose to feel fine. I never have rainout at all.

Thanks for the info. That is close to my setup. Though the hose temp seems too low. Try it again with hose temp at 81 and humidity at 4 as a baseline.

When you hold the ClimateLine hose while using the machine does it feel slightly warm after a few minutes? If not the hose may be faulty.

Something else to consider is getting a hose sleeve to help with the rainout. Padacheek has a few choices.

Other than that I’ll leave it to the much smarter kids in the forum to offer advice.

I guess my concern is that my nose was to dry when hose was set to 67 so wouldn't a higher temp make it worse because the relative humidity would be lower?

I haven't held the hose but when I had it set to auto I could feel warmer air for sure.

Would the higher hose temp reduce the relative humidity and dry nose out more?

Warmer air should be from the heated humidifier, not just the hose. Next time you try it hold the hose after a few minutes and see if it feels warm.

Typically to reduce rainout you increase air temperature or decrease humidity, but too much of either could contribute to your dry nose or rainout. I just use auto for both and have not had a problem, but as I live in a humid place your mileage may vary.

Does it tell you in the app afterwards what settings it used if you're on auto? If so, that might be the best idea to see what the machine wants to do. Then from there I could make mine or tweaks and hopefully find sweet spot I guess.

I don’t use the MyAir app, I use OSCAR which has the climate settings shown in the daily reports. If you cannot install and use OSCAR, just make a note the old fashioned way of what your settings are and the results. Sorry I don’t have a simple answer, maybe others can offer more crisp advice.

Warmer hose air will NOT dry out the nose but less humidity sure will.
You need more humidity to keep the nose happy but with your bedroom temps preferred that sets things up just ripe for condensation happening.

You need to increase the hose air temp and it won't dry out your nose.
I use a setting of 6 and hose air temp of 86 (need it that high because my ambient bedroom temps are mid to low 60s) and the nose doesn't dry out at all.

Other choice is to increase ambient room temps by a lot...which probably isn't so comfortable either.

Thanks I'll try that tonight. Last night I tried hose temp of 65 and let the humidity choose automatically but that didn't work so I went to hose temp of 60 and humidity of 4 and I got by till morning but had a hose full of water.

I think you need to increase the hose temp to at least 78 and put humidity to 4 or so. it’s been a long time since I had to calculate dew point but I think with your low temp setting on the hose you are creating the rainout. Is there a problem with a higher hose temp of >= 78F?

I just leave mine on auto and the machine seems to get it right. It takes about 8.5 hrs until it runs out of distilled water. I'll add that I did start out with a standard non heated hose and it seemed like there was no happy medium. It was either rainout or the sierra desert.

My previous machine was dreamstation and you can't choose specific temperatures for hose. I never found settings that worked besides rainout for my comfort.

I'm going to try the settings recommended by pugsy tonight and hopefully it works. If I wake up with issues I'll try and increase humidity but leave temp of hose the same if I can and see what happens.

Fingers crossed!
