[Equipment] Heated hose, bad night

[zonk]

its matter of choice ... climateline set on auto works best for me and simpler too ... for now its set on 26C

I talked to my brother about it. He said that for this level of flow rate, a glass thermometer is what they use. For their faster flow rates, they have a metal one and, when absolute precision is needed, they use a thermocoupler on their volt meters. The little snot said he won't send me one of them, though. He said something about they're expensive. Some people!

I have a glass thermometer. I am procrastinating something else so playing with this tomorrow will be a good excuse. The hard part will be the shaking it down between each test.

room temp (have an outdoor thermometer I'll bring in)
air without humidifier
air with humidifier and slimline
air with humidifier and climateline

How much time should the thermometer be held inside the hose? I figured string and a chopstick would hold it in place in the middle.

I think the aliens were at work last night. I switched over to a heated hose last night and had a very bad night too.

I think it was the aliens too.

But seriously you started with the humidity at max 100%
Start slowly & go up from there.

Well, I'm an idiot. Oral glass thermometers only go as low as 96F. And my CPAP humidity only goes to 86F. Uh duh...

I am wanting a glass room temp thingy anyway. One day this week I'll go get one and use that.

Feel free to do this yourself! Just carefully document what you do.

1. You have to use your mask with the heated hose and cannot connect the hose directly to your nose. Important!
2. I have a great deal of trouble with using a heated hose as I HATE breathing hot air.
3. You can use your regular hose. Try getting an insulating sleeve; they are cheap but get a good one with a zipper, etc.
4. Humidity? High humidity + cold surface = condensation = rainout. Try turning the humidity down a bit.

That's about the sum of it; I solved my rainout by simply turning the humidifier off but will be turning it back on as we enter cold winter nights (dry air) and I will probably keep it running low and put insulation on my hose to prevent the rainout. It has worked for the past couple of years for me. Depends I suppose on how cold you keep the bedroom and how high you keep the humidifier set at.

Good luck.

We keep the heat low in our house, so I was getting rainout during the first 30 days. However, I had 100% compliance and AHIs were 1.5-9.5.

In order to reduce rainout, i requested a heated hose. Last night was the first night with heated hose and was also my first noncompliant night ever. I was only able to use the machine for 2 hours and slept terribly. My nose was red, too; what does that mean? I set the humidifier on 5, so I guess that I will try turning it down tonight. Any other suggestions.

Turn the hose off and try it that way. Or switch back to the old hose.

Thanks. How do you know if the hose is turned on or off?

...or...
Go by Harbor Freight and pick up an infra-red thermometer.
You just pull the hose off the CPAP humidifier and aim this thing down the open output port.
Zap. Instant measurement!
Since it is a non-contact measurement it never needs to touch the water or get that close to it.
It has 1001 uses around the home too.
Is your A/C cooling enough? Is your furnace as hot as it should be?
For $20 it's a great investment.

Cheers!
