Tube temperature and humidity settings

Hi

Its been a while since I have posted.

I am wandering if anybody could shine some light is there a relationship between Tube temperature and humidity settings?

I am trying to see if this will help in me stopping sore throats and bleeding noses.

Current Humidity Level: 5 Tube Temperature: 29 c

I suffer from mild/severe nose congestion.

I have the Anti-Leak Strap from Pad A Cheek ( https://www.padacheek.com ) but not shore I am wearing it correctly. I shall keep trying

Any tips/suggestions greatly appreciated

Humidity setting is the amount of humidity while the tube temp. indicates the temp of the humidity.
Why not call padacheek and ask for help. Karen, the owner is a member of this board.

Humidity is the amount of moisture in the air that you are breathing.
Hose temperature is nothing more than comfort and/or used to prevent condensation in the hose depending on how much humidity you are using and your ambient bedroom temperature.
So it's the humidity that is needed to address dryness issues and the hose air temp is used either for personal comfort or to prevent condensation in the mask or hose.
Changing just the hose air temp won't help with dryness issues.

Try more humidity and bear in mind you might need to increase the hose air temp but bear in mind you are almost at the max now.
There are additional ways to help reduce condensation in the mask or hose should you end up with it being a problem at max hose air temp.

There isn't one.

The tube temp needs to be set warm enough to reduce condensation inside the tube, so in effect, there's more of a relationship between ROOM temp and tube temp.

Hi Pugsy and others

First of all a big thanks for the replies

I am picking bits from your reply and what others have said. To see if I am understanding it correctly.

A few side notes. Where I live in Australia at the moment its heading to summer so there will be high humidity and high temperature where I sleep

Humidity is the amount of moisture in the air that you are breathing. (I understand this)

Hose temperature is nothing more than comfort and/or used to prevent condensation in the hose depending on how much humidity you are using. (I understand this) and your ambient bedroom temperature. (I don't understand this) What impact does this have on my settings and where does one start? . Should I be measuring my room temperature?

So it's the humidity that is needed to address dryness issues and the hose air temp is used either for personal comfort or to prevent condensation in the mask or hose. (I think I understand this) . To keep very simple if I rise my humidity settings then I need to rise my hose temperature as well. Or does the hose temperature adjustment depend on condensation levels?

Thanks

If your ambient bedroom temps are warm enough all by themselves because you are now in summer (unless you run the air conditioner and keep you house really cool) then if you increase the humidity setting on the machine you might not have any condensation happen in the mask or hose even at the lowest heated hose air temp setting.

As for what to set the hose air temp at to prevent the condensation....to be honest it's a trial and error thing. There is probably some official formula someone could use but I don't know what it is. That requires science above my pay grade and I find it just easier to simply pick some comfortable hose air temps and go from there.

Ambient bedroom humidity itself doesn't affect condensation chances at all. Now it will affect how much water your preferred setting might use though but it won't affect if you are going to experience condensation in the hose.
Ambient bedroom humidity that is just the starting point from which the machine adds moisture to get to your chosen humidity level in the cpap provided air.
Example....suppose your ambient humidity is 60% and your chosen humidity setting provides 85% humidity....the machine will only try to keep the cpap air at 85% and use X amount of water. If it is raining outside and your windows are open and your bedroom humidity is 80% and the setting is for 85% then you very likely will need to only use a very small amount of water to get to that 85% cpap delivered air.
This is why water levels for consumption will vary....our ambient humidity will vary... no matter what the hose air temps might be.

Hose air temps don't affect water consumption at all. They can of course affect whether or not we end up with water in the hose or mask.

My preferred humidity setting is at a 6 on my ResMed machine. I don't know what % that means for delivery but I suspect around 90%.
In the summer (and I do use an air conditioner when it gets hot here because I don't sleep so great in a hot bedroom) I can keep condensation from happening with around a 76 degree F hose air temp...but now it's getting colder where I live and my ambient house temp runs in the high 60s for the most part I find I have to use almost the max heated hose temp to prevent condensation at the same humidity setting. I don't really like the warmer air but I like the condensation even less so I learned to be happy with the warmer air.

So does this help clear up things? I tell people to pick a humidity setting that their nose likes and is happy with and don't worry about varying it during the seasons and just vary the hose air temp as needed for comfort and what might be needed to prevent condensation.
Nasal mucosa don't often like much change in moisture content. When I try to reduce my humidity setting my nasal mucosa will rebel and give me some ugly allergy like symptoms...sneezing a lot, maybe congestion and drainage.

The big auto setting on the ResMed machines...where it is supposed to automatically know the hose air temp to prevent condensation...it doesn't work so great if the bedroom is very cold. I speak from experience there. Works decently during the summer months but not so great during the winter months depending on how warm you keep your house in the winter.
Now my mom keeps her house at about 78 degrees in the winter...if I did that I wouldn't have a problem with condensation in the hose at all and probably wouldn't need to add heat to the air but I simply can't sleep in air that warm.

Many years ago cpap hoses weren't heated at all. Condensation was a much more common occurrence and annoyance. We had to use hose covers to help keep the air in the hose from cooling and releasing that moisture and they weren't always successful and they added uncomfortable weight to the hose for some people.
