Rainout

Post by accessdme » Tue Mar 02, 2010 1:31 pm

There is a new product being developed for rainout called the Rainout Guard. Its a coupling that attaches between your humidifier and tubing. I have seen this work and it reduces rainout more than the sleeves. Basically catches moisture and funnels it back down the tube. I work for a DME and and I see so many patients quitting due to ill fitting mask and rainout so I want to get the word out. I hear it should be ready for purchase by May.

Thanks for the tip, but your description of how the product works is suspect. Are you sure it doesn't fit between the mask and the hose?

Suspect? The way I saw it set up was wtih a 12" hose from the humidifier to the guard then the 6' hose attached to the other end.

You work for a brick-and-mortar DME, right?

I don't see how this would prevent rainout at all. It doesn't control the temperature of the hose after the humidified air enters the tube, so cooling can still occur, which would lead to condensation and rainout. It might help the condensed water drain back into the humidifier, but for someone starting therapy why would this be preferable to a machine that supports a heated hose?

I had rainout one time. Lowered the humidifier below the level of the bed/mask and PRESTO! no more rainout. Does this make sense? The condensation is flowing back down into the humidifier.

BTW, I am totally obnoxious when it comes to cleanliness and clean my mask and tank daily with wipes and wash the whole shebang every weekend with disinfectant soap.

Found handsoap in our own washroom that seems to be odourless! Go figure. Still going to Buffalo to search Target, etc., for a good disinfectant odourless soap.

Be clean. Lower your blower so the rainout flows back into the tank.

The tube temp only plays a small role in rainout. The material of the guard attracts any moisture in the tube so it doesn't get to the mask. For me, the biggest problem with rainout isn't the gathering in the tube it's the water going up my nose! lol.

Then why use a humidifier at all?
Which part (proprtion) of the humidity does the guard attract?
How often does it have to be changed?
How do you dry it to keep it form gathering mold?
Have studies been done about how this affects the pressure? Where and when published?

For me, the biggest problem with rainout isn't the gathering in the tube it's the water going up my nose! lol.
That's why I use a heated hose from http://www.sleepzone.com.au

The only times that I have gotten rainout is when my hot breath condenses in my mask and runs onto my face. The hose doesn't get wet, just the mask, so I don't see how this would help. Since I raised the temperature of my house, I haven't had any rainout.

Sorry accessdme but your answers [quote]The tube temp only plays a small role in rainout. The material of the guard attracts any moisture in the tube so it doesn't get to the mask. /quote] don't make any sense at the light of heat transfer, and thermodinamics laws. Is the guard made of absorbent paper towels How much can it absorb and how are you going to dry it every day and what about the cleanness as my friends noted and all the questions of ozij

Nope, it doesn't sounds any logic at all, SORRY.

Wow, talk about a tough room! I don't make the thing or sell it. Just trying to help. I guess you guys are all PHD's and know everything so I'll move on and try to help those who need it. You sure you guys arent selling heated hoses and sleeves?

You are playing to a tough audience here and an audience with a lot of different experiences so don't take anything personal. It may sound harsh but in reality what you are getting is feedback on your comments the same as I got feedback on mine. I do not take offense at all and neither should you brother/sister.

In my experience with rainout with my ResMed S8 Autoset II and ResMed hose (unheated) I did two things that I think helped eliminate the rainout which I experience only a couple of times.

The first thing was keep the hose elevated above the level of the blower; the rainout is not 'prevented' per se but drains back into the humidifier which I allow to run dry or empty and refill every couple of days and wash regularly (and I wash the hose regularly as well with a disinfectant soap).

The second thing was to insulate the hose itself with a ResMed cover. This helps insulate the warm humid air from the outside cooler air whilst travelling down the tube of course; a heated hose would eliminate the need for a cover (although I think I would still put one on as it is 'cozy') and keep the humidified air at the same temperature as it travels down the hose, preventing condensation.

Lastly, in our case, we keep the room at around 66F at night which I would think is not an uncommon temperature and perhaps even lower than many folks. So our cooling issues should be reflective of the general experience.

Can't really add much more than this.

I bet your description of the device is, at best, incomplete, and at worst, incorrect. You may be doing the producers of the device a disservice. We will watch for news on the device from another source.
