"Rainout" What is it and how can we prevent it ?
"Rainout" is a term that some of you might know and some might not but it is something that we may all come up against if we are using a Humidifier with our machines.
Basically in lay mans terms it is simply condensation collecting in the machine hose when the humidifier is being used. Because the humidifier on normal setting heats the water and normally the room that you are sleeping in is cooler you get condensation forming in the hose, and sometimes you get a rattling sound coming from the hose as the air flows down the tube, which obviously can cause sleepless nights which is not the best thing for us.
So how do we prevent this happening ????
Trial and error is the watchword as adjusting room temperatures and settings on the humidifier will in time cure the problem, also purchasing a fleece hose cover can sometimes instantly cure the problem.
Be patient as this is something that can be cured with a little patience, and I for one know the benefit of using a humidifier so a keep the faith and hang on in there.

I used to suffer from this 'rainout' too before I got my Hose Cover. The other important detail is making sure the CPAP is placed lower than your head (preferably not on the floor though). The hose lifts do a grand job too of keeping the tube elevated, or some people can manage to place the hose over the bed head (depending on the style of bed they have). There's nothing worse than being woken up from decent REM sleep to a face shower in the middle of the night!!

keep it below your head. If that does not work try adjusting your humidity.

I use a Swift nasal mask and HATE the feeling of waking up with a nose full of water! I have discovered that if I keep the humidifier setting at 2 I get no rainout but I DO get a very dry mouth - at the moment I have it turned to 3 which helps with the dry mouth but I have to empty the mask a couple of times a night. I've got a hose lift which doesnt help with the problem at the moment but am hoping that the new mask I have on order might help to make things easier (I can cope with a wet face if necessary, LOL)

Erm.... don't do that! Adjusting your humidifier setting is to try to fix the problem by addressing the symptom, not the cause. Your humidifier is to provide air that is comfortably moist for you - there is a specific setting that will do this for you. I like mine to the max!
Rainout can come for two sources. On a very humid day especially, your PAP machine will extract moisture from the air simply by compressing it. You can get rain-out even without a humidifier. The other - main source - is the moisture supplied by your humidifier being condensed out in the hose by an room air temperature below the dew point of the CPAP air. So, there are two solutions - heat the room air temperature (immigration works better than expensive heating) or heat the CPAP air. A clever - and now wealthy - gentleman in Australia invented and patented the 'Aussi heated hose', retails at about £80 inc postage. They are worth every penny!
If that is too rich for you, have your hose running upward from the machine to you, a hose sheath, hose under the duvet/pillow - I've even heard of wrapping it around your leg!
Trust me - the heated hose is the way to go.

Would you say the heated hose is better than the heated hose that comes with some Fisher Paykel machines, and the latest Resmed S9?

I'm going to guess no better and no worse. The Aussi hose is for machines other than the ones you mention - the ones without a rain-out solution built in!

Just what I thought, but a heated hose is cheaper than a machine!

The heated hose is made by Sleepzone and can be purchased from Australia. Here's the link http://www.sleepzone.com.au/ However, Tigers Fan also informed us of a new heated hose which should be coming to the UK in the future and am sure he'll keep us posted about it. Meanwhile, if you don't purchase the Aussie one, you may find your problems subside during the warmer weather Katrina.
