Getting very wet...

[Stagecoach]

Hi all and thanks for letting me join the forum.

I have been using a ResMed APAP S9 CPAP Machine with Humidifier for about a year now and it is not too bad but recently I have a problem.

After approx. 2 hours the tube starts to fill up with moisture and seems to make some weird noises (Gurgles etc)
I have to disconnect tube and dry it out before I can continue.
Any ideas what I am doing wrong.

Thanks

It sounds like you're getting excessive condensation in the hose. The most effective remedy is probably to get the heated hose option as this should greatly reduce the amount of condensation.

The amount of condensation is determined by the temperature setting of the heated water tank so you could also try just lowering the humidity setting on the cpap machine.

Condensation can also be affected by the difference in temperature between the air in the tube and the temperature of the room it is used in. So if the room is very cold, you are more likely to get condensation and making the room warmer could help.

CPAP hose covers are something cheap that you can try and may help some but are not as effective as a heated hose.

Routing of the hose can also help. I use a $12 hose hanger that suspends the hose over my head so if there were any condensation in the hose it would tend to run back down into the humidifier.

The only thing I can think to add is that placing the machine lower than your mattress level may help too.

Hi, its called rainout. The only cause that I know of is the cpap machine is on a surface probably like a bedside cupboard. This makes the water collect in the tube and then of course it flows somewhere, usually your mouth and it is unpleasant. Put the machine much lower. Mine is on a plastic box on the floor, never had the problem since I put it there. Hope it helps.

A couple of things may have changed to cause this:
1) Increasing the humidity level for the humidifier.
2) A drop in the room temperature.
3) A change in the hose routing so that there is a significant low spot where the water can collect.
4) A change in the location of the CPAP that creates a low spot in the hose position.

Possible corrections:
1) As suggested, switch to a heated hose.
2) Re-route the hose so that the condensation can drain back to the machine either by lowering the machine as suggested or by using a hose hanger to elevate the center section of the hose.
3) Wrap the hose in insulating material such as a Hose Cozy or some fleece fabric to reduce heat loss from the hose.
4) Increase the room temperature a little.

Do you need the humidifier? I only use mine when I get stuffy.

Thanks all for replies

What I think I will do is get a heated cover and route the pipe with a hanger.

I have already lowered the machine about a foot below pillow and humidifier pretty much needed else I wake up with a very dry mouth.

Thanks again for all your great suggestions..

It's two separate things a heated hose like this one https://www.cpap.com/productpage/resmed ... ntrol.html and/or a fleece cover for the hose.

Anyone new, planning to lower the machine:
Always put something under it, like a box or small stool.
Putting it directly on a solid surface floor (or whatever) may be noisy;
{{and on carpeting, too easy for a dust bunny invasion}}.
An old mouse pad or sheet of padded shelf liner will help silence the sound box effect.

If you've been using it for a year without problems, and conditions haven't changed, maybe something isn't working right. If you already have a heated hose, maybe it isn't heating.

weather conditions change, and if you read the thread, you'll see that the OP doesn't have a heated hose.

I did read the thread. I don't see where it specifically states that the OP does not have a heated hose. When troubleshooting a problem, solutions are very often missed because certain things are assumed and questions are never asked.
