Cold air in cpap

[Dreamingofsleep]

Hi again,
I am curios. Sometimes the air from my cpap blows too cold and it almost "stings" my nostrils. Now I often have water in the tank for the humidifier, but only set on zero. However, I thought maybe the air would be warmer if I used humidity, so I set it on 1. It still was not warm or close....Now I asked the DME about this and she really didn't have an answer. Isn't the air coming out supposed to be heated? (note: I don't use the heated hose). Your help is much appreciated as I really hate it when the air is so cold it is uncomfortable. It doesn't happen often, but often enough if you know what I mean

The settings 1 through 5 will heat the plate under the water chamber and give you warmer, moister air. Setting 0 will provide no heat but a passover humidity that would feel colder.

You can check if your humidifier is heating up by removing your water chamber in the morning and feeling the bottom of it (after giving it a minute or two so it's not uncomfortably hot).

I found the PR System One (I have a 750) to blow air that is a little too cool to be comfortable in the winter, even at setting 4. You can also get a hose cover to minimize heat loss, it might be enough. But I think you need a setting of 1 or 2 to at least warm the air a bit.

What is the bedroom temperature?
Back last winter even with the humidifier on the PR S1 750 machine (not a heated hose model) turned to max setting in Classic mode the air was uncomfortably cold to my nose. I called it ice cube nose. Classic mode is the mode where the most heat is used.
If your humidifier is set to 0 or 1 in the normal new system one default method (it uses even less heat than Class mode) then there is going to be very minimal heat applied to the water at the setting of 1 and none at a setting of 0. The heat is designed only to warm the water enough to release some moisture into the air. It isn't going to warm the air itself all that much. None if your bedroom is on the cool side.

Thanks, guys

So..you are saying if I turn the humidifier up more the air will be warmer, right? I did turn it up today and felt it with my hand..it didn't seem "warm". The bottom of my water tank was warm though. So what should I try? Should I go ahead and try it higher even though it wasn't feeling warmer today on my hand?

Also, last night after I did turn it up I woke with moisture and water drops below my nose. The DME said that means I have to keep it at zero?? What do you think about this?



Thanks again for your help.

As Pugsy says, it depends on the temperature of your bedroom. You could turn it up to 2 or 3 to see if it's less cold. If you put the machine lower than your head, you'll minimize the chance of rainout.

Thanks, Randy
I do like my bedroom pretty cool. I've had my windows open to enjoy the start of summer, and our nights are always quite cool.

The heat produced by the humidifier heating plate will never produce enough warmth to the air that the air will seem warm to your fingers. It just can't. Heck, even with the heated hoses the air isn't all that warm...it just isn't brutally cold either.

The condensation in your mask...that like is a combination of the moisture in the humidified air and the moisture in your exhaled breath condensing in the nasal pillows. It's called rain out...annoying, yes...harmful, no. Biggest problem with it is if it wakes a person up a lot during the night.

Solutions..
1. Warm up the bedroom air temp so that the air coming through the machine is warmer to start with.
2. Use a hose cozy to help insulate the long hose so that any warm air from the humidifier does have a chance to make it through the long hose to the mask level....this would be the first thing I would try...it might be enough. Padacheek.com makes the best one that I have seen. Denser fleece with minimal weight compared to density. It will insulate better.
3. Padacheek.com makes some barrel cozies to help insulate the nasal pillow barrel...these work great (I have one) and are super comfy against the skin. I think she probably has one that will work with the GoLife pillows.
4. If your machine is a 60 series machine..buy the heated hose option...if a 50 series machine buy a stand alone heated hose.
I used the Hybernite 2300 with my 750 machine...works great.

Remember...there is a bit of warmth generated by the heating plate but by the time it travels up that 6 ft hose in a cool bedroom any warmth will be greatly reduced.

Pugsy, thanks so much! Again I feel reassured that there are solutions instead of having to be stuck with the apathetic responses from the DME!

Hugs and thanks,

Hi,, I am having the same problem with the cold air. I have been trying to use my machine for 4 months and what is suppose to give me a good night sleep is waking me..did you find a solution to the cold air problem? I have insulated my hose, when it wakes me my plate and water is cold to the touch..
If anyone know a solution, I am using a resmed s9 series. I feel the frustration I am having try to use the machine is far worse for me than the sleep apnea.
Thanks..Lynn

Route your hose under the covers and next to your body to warm it up. That's what I do because I never use heated humidity and my bedroom is around 60 degrees.

I dunno.......maybe your machine has a "problem" of some type. Have you contacted the supplier you got it from? Should have a two-year warranty.

You say you have the S9......if so purchase the ClimateLine Heated Hose for your machine, you can then set the hose temp where you like it so you get warm air from the heated hose.....well worth the cost!!

I have mine at 83.....nice and warm, never a cold nose

Thank you Tanglenose, I will check into this. I can turn up humidity , but not temp , it is factory set at auto..Automatically set to wake me up in 2 hours with blasts of cold air. ..LOL
Thank you Wulfman, this is my second machine due to cold air,,it's gotta be me..

From my understanding from reading the manual, you can change/override those settings.

From the manual:

Climate Control
When the ClimateLine heated air tubing is connected and Climate Control is
enabled, the patient can adjust the air temperature to find the setting that is
most comfortable for them.
When set to Auto, Climate Control prevents rainout by maintaining 80%
relative humidity in the delivered air. If Climate Control is set to Off, Humidity
Level and Heated Tube temperature can be set independently.

And:

Managing Climate Control
Designed to be ideal for most patients, Climate Control Auto enables the automatic delivery of a constant
value of absolute humidity while protecting against rainout.
To allow for increased flexibility, Climate Control can be turned to Off in either the Patient Setup (when
enabled) or the Clinical Setup menus. Setting Climate Control to Off disables the automatic control of
humidity and allows the patient to set humidity and temperature levels independently. However, rainout
protection is not provided when Climate Control is off.

Thank you for this info Wulfman, I was wondering how to do that!

[lynnh]

I will give that a try Wulfman..I would rather have a rain out any night..Thanks...Happy New Year.
