Ok, so what *else* causes hose rain?

Post by AlanMacNeill » Tue Sep 27, 2011 8:45 am

This is weird...

I got my new machine about 11 days ago, and did my first weekly intensive cleaning this past Sunday, as per instructions (well...okay, not completely per instructions, as that was day 9 not 7, but my routine is weekly maintenance of stuff, not just the CPAP, is Sunday, so I figured I could slide a couple of days to get it onto the routine moving forward).

The humidifier chamber was filled with the 1:10 vinger:water solution for 10 minutes, emptied and let air dry inside (paper towel wipe off outside), the mask was broken down and all components washed with gentle dish soap and warm water, the hose was washed inside and out with gentle dish soap and water (because this machine has a heated hose, the instructions say quite dramatically NOT to use vinegar in the hose), then let hang dry for about half an hour before reassembly.

My humidifier is set at 80 degrees.

Sunday night I had significant rain in the tube, I mean we're talking hurricane hitting landfall levels of moisture coming out of the tube.

Same thing last night. I ultimately had to turn the humidifier temp down to 70 and literally take apart the mask and tube again and shake the living c**p out of the tube to get all the water out, then no rain from there, but I did have massive mask fit issues (despite not changing the headgear sizing at all that I'm aware of)

Everything I'm reading says that I've done my job correctly, and that the copper wire and sensors in the tube are supposed to prevent rain...

What should I take a gander at to figure out the cause? The 70 degree air is a little too chilly for my comfort, but rain is worse.

I actually started not adding water to tank and turning humidifier off so it doesnt damage the machine. I like it this way. Air is humid here already so my nose doesnt get dry at all and no moisture or rain problems.

I have read where someone has filled their tank to the desired full level and if they turn the machine on full blast and not be masked up that some of the water from the tank gets blown into the hose. Seems to depend on pressures used too.
Might experiment with having mask on before turning on machine or using slightly less water in the tank.

This problem has been mentioned here on the forum by others.

Sure you didn't still have a bunch of water in the hose after cleaning?

I hang mine on an "s" hook in front of a kitchen window, and I can still see water droplets in it several days later. In fact if I wash my gear on Saturday, it's usually around Wednesday evening before I see the hose is completely dry.

I cycle the hoses I have so I'm always using a clean, completely dry one. I guess you could run the machine with the wet hose on it and let it blow until dry if you don't have a spare.

Cheers,
xena

Do you use a hose holder? http://www.amazon.com/s/ref=nb_sb_noss? ... ps&x=0&y=0.
Take a look at this information. http://www.apneasupport.org/about790.html
Hope that this helps.

This was one of the threads from yesterday. Maybe these adjustments would help you.
If you are using the Climateline, there is a feature where you can go into settings and change the ability to regulate the temp of the hose vs the humidity. Where they are two separate functions to adjust.

http://www.cpaplibrary.com/machines.html

It'll show you different features on how it works.

I have never had an issue with moisture in the tube..

don't all machines continue to run for a bit after shutting off to assist with drying out the tube ??

Is this caused by overfilling the tank or using a high pressure with a full tank ??

I never wash my hose! It seems nearly impossible to get all the moisture out, and I figure I'm in more danger from mold growing in the trapped water in the hose than the clean air blowing through it. And I have used the same hose forever since Crapria doesn't seem to understand what the heck a PERFORMANCE hose is--I don't want to have to fight the kinks in the crappy cheap hose they insist on sending out instead.

I haven't died yet--respiratory system is doing pretty well, actually.

No, only the ResMed machine.

The other users who have had this problem stated that they were certain the tank was not overfilled.
Since it is not easily duplicated we aren't for sure if it was high pressure and a full tank.

Pugsy, I have seen this first hand. Yes, if you fill your tank to full or if you turn the unit on and don't put your mask on right away, water will blow into the hose (at least on my S9 AutoSet model).

Thank you for confirming this. It should be easy for someone to troubleshoot to see if this is the cause for copious amounts of water in the hose for Resmed S9 users. I have never seen it reported by PR S1 users and I have not seen this myself but then I mask up and then allow the machine to come on.

Troublesome kids pouring water in the hose can be a problem too. I've seen that first hand too.

Back to first principals.
If everything is connected correctly and working, I don't think you can get rainout in a ResMed S9 heated hose.
What are the possible explanations.
Is the hose connected correctly to the machine. Push it on and rotate 90 deg. I suspect this is correct as otherwise you get a different screen display.
It is possible to get rainout in some masks. If this is the case the mask will have water but the hose will be dry. I have had problems with my Swift Fx.
It is possible as discussed above to blow water into the hose if you have a massive leak (Machine on mask off)
Personally as my hose is always dry I only wash it very occasionally (every 6 months or so). It would need washing weekly though if wet.
The optional humidifier chamber can be taken apart and is much easier to clean.
I run my temperature at 78 deg and have never had an issue
If all the above are OK I would suspect a problem with the hose or machine.
