CPAP humidity and asthma
I think one of the issues I've been having in getting used to my CPAP is getting the humidity setting right for me. If it is too high, it seems to adversly affect my asthma (which is mild in general). I realize that this is something I will need to play with to get to the right point.

Humidity too high makes my lunds feel 'tight'; but without the humidity at all didn't work for me either.

If anyone with any experience with similar issues has any suggestions and/or input I would appreciate hearing about it.

TIA,
dobie

Hi dobie,
You say that if you have your humidity to high, it makes your lungs tight, try turning your humidity back a notch from the point at where your lungs get tight and see if that will work. You are right, humidity settings are an experimental thing for everyone. Hopefully, you can find a setting that will work for you.

What Trish said.

The S9 can detect the humidity level of the air coming into the machine. So if the air is already 40%, and you want it 80%, it will only add enough heat to make that 80% mark. That's why some nights we use all the water and other nights we use very little.

By turning it down a bit, you can then find out where your need is on the scale.

I suggest starting a diary of sorts where you write down what the setting is and how you felt the next morning. That way you remember which setting was the best and which really did not work out.

RE: CPAP humidity and asthma
Humidity and mask choice is about the same, individual preference, what works best for one person might be the worst for someone else

I don,t know about asthma but I find the heated hose (ClimateLine) extremely useful to have, auto adjust humidity to a constant level

Tinker.

Humidity seems to be very much trial and error. Don't assume that more humidity is better. Some people find things are better with low humidity even when you'd think more is better. For some, the more the better.

Some find their humidity need changes from night to night or with the seasons.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

RE: CPAP humidity and asthma
thanks to all for the input.

I do have a climateline hose, and i am playing with the humidiy. I currently have it set on my escape at a 1 at a temp of 75 degrees (which is what the inside house temp is at).
We have a weather station thing that measures temp and humidity inside and out and I put it in the bedroom last night and this morning it showed an inside humidity of 60% (I have no idea if those things are at all acurate)

I slept pretty well abeit not long enough as I went to bed later than usual.

Thank you for this idea. I started last night making a record of my changes. I think this will be very helpful in narrowing down what my settings should be.

RE: CPAP humidity and asthma
you can get the small humidity / temp monitors from Wally World made by
AccuRite.
I have several and they are usually within a point or two of each other.
If you are getting 60% humidity that is too high for your room. (vermin, mildew/mold growth love humidity!)
Room needs to be 50% or less. A dehumidifier may be a bit costly up front but will save your house and health in the long run.
It also takes a load off your A/C by removing water from the air that *holds heat*.

For your CPAP you might find that 75% and higher (in the delivery hose) is better for prevention of dry mouth/throat.

Hang in there and keep trying!
