Cold air from CPAP

Last night, for the first time ever, I started getting very cold air from my CPAP. Cold enough that it was very uncomfortable and caused me to just take the mask off after about an hour and sleep "naked".

It was cold outside, but the heat was on inside, so that's not it. The humidifier had water and was set to "1", which is where I normally have it, so that's not it.

Any ideas?

UncleLeo, the CPAP (without any heat added other ways) just takes the air in your room and blows it through. It doesn't change the temperature at all in and of itself. Therefore, if there was a change in temperature of the air you were getting, it had to be because the temperature in your room was different. Sometimes something the same temperature can feel different to us from day to day. Also, because of the way the airflow is concentrated, nasal pillows can also "feel" like they're blowing colder air than nasal masks are, which dissipate it more. But if you haven't changed masks, that wouldn't be it.

Why not just turn up the HH and enjoy the heated air instead of trying to find the cause of your concern. I use a flannel cover on my hose as I cannot tolerate cold air blowing in my nose. The warmed water does indeed heat the air to a degree that it is comfortable. Works for me! jim

I did turn up the heat, though I only gave it about 20 minutes before I gave up.

We'll see what happens tonight.

Heated humidifiers don't warm the air til you turn them up really high (at least, that's true of Respironics integrated humidifiers). If you don't want to raise the temp in your room (which, if nothing else has changed with your CPAP setup, I'd suggest), then turn your HH up to the max setting and see if that helps. Be prepared for some rainout though if your room is substantially cooler.
