Night Sweating / Humidity Issue
I have had a ResMed S9 AutoSet with H5i Humidifier for about a year now. I also have a Fisher & Paykel Eson nasal mask and a ResMed ClimateLine. I live in Maine and during the colder months, I get rainout and significant night-time sweating. I have tried to adjust it as best I can, but I am looking for some help from anyone else who might have experienced similar issues. I have moved the machine lower to the ground so that the moisture in the tube has to fight gravity which has helped some with the rainout. The sweating is only helped if I sleep in just my underwear and without any covers on me, which can get a bit chilly. The guy at the Apnea Clinic at the VA Hospital said a room humidifier might help. I am not so sure that it would help with the night sweats. He thought the heated tube might be working too hard to maintain correct moisture in the system which causes a quasi overheating of sorts. I have tried turning off the humidifier and that causes horrible dry nasal passages. Not sure where to go from here.

The ClimateLine on auto designed to protects against rainout and you can adjust air temp to your personal preference 16-30C (61-86F)

I had it turned all the way down to 60F and still had problems if I got under even just a thin sheet. I also tried OFF and did not have sweating problems, but my nose was as dry as a desert.
Thanks for the welcome zonk!

Just to be on the safe side, talk to your doctor about night sweats, can mean different things

On warm nights, I get a bit sweaty but I need to use the humidifier, otherwise my nose won't be happy Smile
There is fine balance, matter of trial and error, everyone is different

I agree with you. I cannot live without my humidifier either. I will speak to my doctor when I see him in December.

I agree with zonk. You should not be having night sweats in Maine in November. And, the CPAP/Humidifier/heated hose should not cause night sweats.

Hi clrobison,
WELCOME! to the forum.!
I agree, you should mention to your doc about the night sweats.
Hang in there for more responses to your post and much success to you as you continue your CPAP therapy.

I'm confused. Does "night sweats" refer to condensation in the CPAP hose, or to perspiration? If it is the hose, get a heated hose and consider adding a cover like a Hose Cozy.

I'm understanding it as perspiration due to the "underwear" comment.

Sweating at night can be caused by a lot of things. Although OSA is one cause of night sweating there are more than a dozen other reasons and some of them are serious conditions. I'm in agreement with the others, bring it up to your doc. If it is caused by OSA, that should be handled with CPAP. Perhaps a pressure adjustment is needed.

Leave the unit set to "Auto" as far as the climateline hose is concerned. Do not turn down the temperature. Close to, or especially below room temperature. shoot for at least 5 deg above room temps if rainout is a problem. If your room temp is 66, set the humidifier temp on 71. If you set the temp below room temp, it just does not come on. And does nothing to retard condensation. The ONLY thing it does is keep the tube walls warmer than the surrounding air.

Climateline (specifically the setting temperature) has nothing to do with night sweats.

Me? I keep humidification at minimum. Often time no humidification at all.
