Humidity and AHI

I have a heated humidifier and for about the first 2 months of therapy I kept the setting on 1. I often had rain out which was bothersome. Then about a month ago I tried putting the setting to 0 (passive only, no heating). I no longer had rainout, I experienced less congestion and I did not have any negative issues.

Last night I accidently went to sleep with the humidifier on but I am not sure what the setting was. I woke up due to the rain out. I drained all the water out and set the humidity back to 0. Then I went back to sleep. Upon checking the results this morning I see that my AHI shot up considerably for the portion of the night that the humidity was on. After I drained the water and set the humidity back to 0 my AHI appeared to be back to normal. My question is, have others found that their AHI was higher when the humidity was set too high? Has anyone found a correlation between humidity level and AHI?

TIA,

Jeff

I think a lot may be due to the fact that so many people get nasal congestion with a higher setting, making it hard to breathe, or forcing them to breathe with open mouths, equalling huge leaks. A lot of people (Y's truly) don't use a humidifier at all, and have no downside to doing that. So while it isn't therapy in itself, it helps people who need it, but doesn't hurt people who don't.

Yes, I have.

Not for me. I need all the humidity I can get. Something I think the System ONe does not provide enough humidity even at max level.

If I don't have humidity then I have congestion.
