Nano & the ClimateLine Hose

Am currently using both the ResMed SoftGel & the ResMed Activa LT cushions (both use the same frame).

Just ordered the ResMed Nano Nasal Mask to try.

The frame for the SoftGel & Activa LT connects DIRECTLY to the ResMed ClimateLine Hose.

Undoubtedly, the short hose of the Nano will also connect to the ClimateLine hose - won't it?

Will the short hose of the Nano interfere in any way with the correct operation of the ClimateLine hose?

The ClimateLine Hose is supposed to be able to sense the temperature of the air AT the mask. Will the extra distance that the ClimateLine is connected from the mask (i.e. the distance of the Nano short hose), mess up the ClimateLine's ability to sense the temperature at the mask.

Looking at the Nano on the ResMed website, ResMed says to choose "Pillows" as the mask setting. Why would the setting be "Pillows" for a Nasal mask?
Is it because of the small size of the Nano?

I suspect it is the size of the cushion. The amount of space in the Nano cushion is going to be reduced quite a bit due to its small size when compared to the other nasal masks which are typically much larger. The vent rate is going to go more along the lines of the vent rate with the nasal pillows and that's all that mask selection choice does anyway..it tells the machine which generic vent rate to use for leak calculations.

Yes, that won't be an issue at all. The actual coupling on the short hose fits any long hose.

The air temp sensor is going to be a short distance away from the mask/cushion itself due to the length of the short hose.
So it will probably affect it just a little but I don't see it being a huge negative factor. At worst the air will be just a bit cooler (from slight cooling along the short hose depending on your bedroom temp) when it reaches the mask. Might increase the chance of rain out at the mask level just a tiny bit. Should that happen I would imagine a couple of degrees temp would fix it and it might not even happen.

I had no issues when I used the CLimateline and none now with the PR S1 heated hose...and I have used nothing but nasal pillow masks that have all had some sort of short hose with them.

I am using both the Climate line and the Nano and have had no issues with rainout. Currently set at 80 degrees F. I also use an Opus 360 nasal pillows. It has the short hose between the mask and Climateline. I have never had a problem with that one either.

I have never had any rainout problems, so I expect I will not have them with the Nano & it's short hose being between the mask & the ClimateLine Hose.
My bedroom temperature is not that low to begin with, so that should help to keep any rainout at bay.

However, should I have rainout problems, I assume I should DECREASE the ClimateLine hose temperature since I don't plan on changing the bedroom temperature?

My Wisp, Swift FX, Nuance, and Elan masks all have short hoses.
It has not been a problem, but maybe I'll make a short hose cozy.

I like to go au natural!

Besides, would not a hose cozy on the short hose add too much weight - especially on a Nano mask that is so small & light.

I tried the Nano, and sent it back, but Karen's cozies for short hoses should be light enough for most short hoses.
The Nuance hose is the lightest weight hose I've seen, and I would try it anyway--maybe use the top loop if the weight affects stability.

No, I would increase the ClimateLine temp...assuming you are using it in automatic mode.
Increasing the temp a little would help keep the air going to the mask just a little warmer and hopefully not release the moisture.
In automatic mode the goal is to maintain 80% humidity no matter what the temp. If you lower the temperature of the air then it will be even cooler at the mask level.

Now if you weren't using the Climateline hose...pretty much the only choice is to reduce the humidifier setting so that it doesn't put as much moisture in the air in hopes that the cooler temps won't cause condensation.

Remember the physics of condensation...warmer air holds more moisture and it is when the air cools to a point that it can no longer hold the moisture that we get condensation.

If you keep your bedroom on the warmer side I doubt you will have any issues. The only time I have much rain out issues is when my bedroom temps really drop in the winter. I like a cold bedroom and at night I turn the thermostat down in the house to 55...and my bedroom is away from the thermostat and open on 2 sides...one of them being north and with a window on each...plus it's an old farmhouse that someone forgot to add much insulation to...the bedroom gets really cool in the winter.

My original thoughts were if the bedroom is cooler than the temperature setting then you could get rainout. And I agree with you that could possibly be the case if I were NOT using the ClimateLine Hose in Automatic mode.

But, I do ALWAYS use the ClimateLine Hose in Automatic mode - even in the Summer, when I just reduce the temperature a bunch to a more tolerable level.

And I was aware that the 80% Humidity is maintained in Automatic mode no matter what temperature setting you use. I just didn't think about that when I proposed LOWERING the temperature.

So, I also agree with you that LOWERING the temperature would NOT be the way to go. And the more I think about it, the more I am pretty sure I will NOT have any Rainout issues in the 1st place.

So, when the cold really sets in, I will raise the temperature back to the Winter setting of 80. If I do get any Rainout (very doubtful that will happen), I will decrease the temperature very slowly.

THANKS for your input!

Also THANKS to msla & chunkyfrog for their additional input.

It is always good to have a 2nd set of eyes look at it.
I was anticipating problems when there will pretty certainly be none.
