S9 raining!!!

I have the S9 with the climate line hose. I put the hose cozy from my regular hose on the climateline. I was using the Swift FX and had the S9 temp set at 73. I am npw trying ( not very successful) to use the Hybrid. Had to raise the temp. to 78 as the rush of air in the mask was uncomfortable. Felt cold. Last night the room temp. was just over 71 degrees and the room humidity was 42. I had played with the Hybrid and did get a better fit. Still must be leaking as my 95th leak rate was 19.2 and the median was 12. The data is not quite correct as I had the machine on while removing the mask. I was in a deep sleep and even though the data showed leaks my pressure was running from 6.5 to 7.6. My Autoset is at 6 to 14.I awoke due to water dripping from ther mask. It "broke" the seal and there were so many leaks that I turned the machine off and went back to sleep. Why did I have rainout with that heated hose? Should I set the temp lower? What is the relationship between the temp setting and humidity setting? Thanks

Bob,
There are many people who know a lot more than I do but one thing I would try is to set the hose on auto. This setting gives you 80 deg. air at 80% hum. The sensors in the hose are supposed to sense rainout and adjust automatically to eliminate it. Works for me. Good luck.

I too am not all that knowledgeable about the hose you're using. Are you sure the moisture collection is coming from inside the hose versus mask? Or is it possible you also have mask moisture collection? I had to make a little white jacket for my nasal pillow mask to stop that pesky problem.

Hi,

The best thing to do is to check if the climate control is on auto. Here is a video that will help you navigate and I will also explain it. http://www.sleepnation.tv look for the post on the S9 machine.

To access the clinical menu hold the turn dial and the silver button with the check marks down together for a few seconds until the screen changes. Then turn the knob down to the options menu. Click once to enter and climate control is the first option. Make sure that it is on auto.

Good luck

Thank you all: My unit is set on auto. The climateline hose is automatically selected. I think that when you set the temp. it automatically sets the humidity. I am going to try a lower temp. tonight. Maybe 74. I think as long as the ambient temp is not too cold I should not feel any cold air in the mask.

I use the same equipment as you with a fx pillow. Room temp. last night was 68 degrees and climateline temp set at 78 degrees. I did not experience any rain out. So I don't know what to tell ya.

The ClimateLine hose is supposed to be used without any covering. I would suggest removing the hose cozy and see what happens. If you set the temperature too high with the cozy you can create a problem overheating the hose and create a system fault.

The cover is coming off right away!!!

The other possibility is that the hose is defective... you should definitely not get rainout with the climateline hose and the machine set on auto climate control. But, I agree... the first step is to remove the hose cover.

In the AUTO setting, the S9 should maintain the humidity of the air within the hose below saturation, so rainout should hot occur inside the hose. But that's where the rainout protection ends. If your mask has a length of hose that connects the mask to the Climateline hose, you definitely CAN get rainout in that section, or within the unheated mask itself.

With my Opus 360 mask, and ClimateLine hose, I get a little rainout where the unheated section of hose connects to the mask. On cold nights, when the cat meows until I lift the bedspread for her to crawl under, I get a drop or so of water bubbling between my nostril and the nasal pillow, and that's enough to wake me out of a deep sleep. When that happens I simply lift the nasal pillows, wipe them and my nose off with a tissue, put the pillows back in place, and that's usually all I need to do.

You might take a terrycloth handtowel and rubber band it to the unheated section of hose and see if that is any help. Ideally, the ClimateLine hose would connect directly to your mask.

Re: the snuggy, it really doesn't matter whether the Climateline hose is covered or not. There's a thermistor at the distal end of the hose that measures the temperature of the humidifed air as it leaves the hose. That temperature reading is used to adjust the current running through the resistance wire wound around the hose, and the temperature of the water within the humidifier so that the humidity does not exceed 80% saturation. Any extra insulation provided by a snuggie just means the hose uses less power to keep the humidified air warm. I keep mine covered because it keeps the hose from kinking and sticking to my arms when I move around.

Padacheek might make something which covers that unheated section.

Tried the Hybrid with the hose cover removed last night. Rainout again. I switched to the Swift FX and it was OK?? When I had a race car learned that you should never make a lot of changes at the same time. Makes sense. There are so many variables. I have switched back to my Swift and will try it with the Climate Line and cover for a week. Temp setting on the S9 will go back to 80 ( factory setting). My room temp stat is set at 72. Our hunidity varies as we are one block from the sea. Last night it was 30 when I went to bed but is 45 inside and 62 outside today! A quick question: Does the climate line interact with the S9? So if you set the S9 to 80 does the climate line also run at 80. If it uses a thermistor how does it sense humidity? The thermistor should only sesne temp. Thanks

Yes--the climateline interacts with the S9--and uses the temperature set on the machine. There is a temperature sensor at the mask end of the tube to ensure that the air temp coming out that end is what the S9 is set to. I'm not sure if there is also a humidity sensor on the tube too too, but there is at the H5i to keep it to 80% relative. It sounds like maybe you are getting condensation in the Hybrid mask itself--did you find that the tube had condensation too, or just the mask? Your own mouth breathing may be what is causing the condensation when wearing the Hybrid mask.

jmelby: I was also thinking that it might be my own moisture but when I looked at the hose the inside had water droplets and I used a lot of water. It is very hard to see the water level in the tray due to condensation. I am going to switch to the washable tray as you can open it up to see the level or easily empty the tray and wipe away the condensation.

They don't need to actually sense humidity. It can be accurately calculated from the temperature of the water in the humidifier reservoir, airflow over the water in the reservoir, and the temperature of the air leaving the end of the tube.
