New to S9 auto and humidifier issues.

I'm having issues with humidity. I can't have too much or too little w/o having uncomfortable (to say the least) issues. I was just changed to a ResMed S9 with it's humidifier and all my old symptoms from both too little and too much humidity have come back as the humidifier Auto setting wasn't working enough for me. RT told me to change to manual, but the manual was running warm and cold. My RT and I thought it wasn't working so he came to check it today.

He called ResMed while he was here and was told that on auto setting, the humidifier for the S9 is controlled totally by the humidity in the room. The metal under the tank will actually go from quite warm to actually cold and the air coming through the mask can/will change temp/humidity to varying degrees. (I felt that and I don't like it)
Often, the highest Auto setting is not enough humidity for some people, so they are told to change to manual setting to get more. In manual setting the temp setting of the climate hose (example: if humidifier is set on max of 6 and hose is set to max degrees) can mess with the humidity setting of the humidifier. If the hose temp is too high it can actually cause the humidifier to stop heating because humidifier senses the heat in the hose and quits heating, and you end up with a lot less humidity. (cold dryer air imo) So I'm to try turning the heated hose down or off to get a more steady type of humidity as my other machine had.

Many of you have this set up... is this true, or is just BS?

1st - you may want to consider keeping all of your posts in the same Subject thread.

2nd - When set to "Auto", it maintains a humidity of 80% regardless of the temperature you set.
In fact, when in "Auto", the temperature is the only thing you can change.

I know that some people feel that they can better control everything by using the "Manual" mode - where you can change both the humidifty & the temperature.

My own personal opinion (and an opinion is all it is) is that "I" cannot better control the outcome by using the Manual mode.
So, I use only the Auto mode & change only the temperature as needed (higher temperature in the winter months & LOWEST temperature of 60 during the summer months).

Excuse me. I thought this was a bit different and didn't want to get off topic from the last person's question of how to change the Auto setting.

Thank you for your opinion and reply. I will be careful where and what I post in the future.

NOTHING to excuse - It is all MY fault ! ! !

I saw your name as the last respondent in that other thread & MIS-read it as though YOU were the OP - hence my suggestion that you keep all of your questions in the same subject thread.

Since you are NOT that person, my suggestion seems silly at best.
I have other words to describe it, but this is a public forum.

Again, please accept my apology for such a stupid mistake.

No problem. No harm done.
May I suggest you read the other thread post before making suggestions? Touche!
I couldn't resist that comment. I have a wicked sense of humor at times. Seriously, no harm done. Thank you for the apology, totally accepted!

I tried the Auto settting. The RT left it set for me. I woke up with the old dry throat so sore I couldn't swallow being back. (and NO, I'm not a mouth breather, this isn't an issue that is just morning, when it hits it's 24/7 and hard to kick back into place) I set the auto up a bit for a few nights, then I maxed it, same deal.
By then I was miserable so called RT and he had me change to manual settings. Well, that didn't work.
What the ResMed guy is saying may well be true.

I just spoke to someone at the Resmed Clinical Team because the auto setting can get too hot for me over 82 degrees, but I do not have enough humidity.
It seems some people need more humidity but cannot take the high temperatures (like myself), her suggestion was to start at 78 degrees and 5 on the humidity in the manual mode. She mentioned because my sinus have dried out and painful it could take a few weeks to sort itself out. I may have to go up to 5.5 humidity and increase the hose temperature as and when required.
You might Resmed yourself and ask, they spent about ten plus minutes talking to me and answer my questions and explaining.

Do you have something like Simply Saline nasal spray handy? When I forgot to add water to my tank a few times and it went dry I had some really nasty dry nasal mucosa and sinuses. It took several days for things to settle down and get back to normal. Adding Simply Saline nasal spray frequently during the day was something I figured out that seemed to help speed up the "healing" process the last time I forgot to fill the tank.
Adding the saline spray helped the rehydration process speed up a bit and I still use it daily just as a precaution.
If you are already doing this..then never mind but if not then it sure wouldn't hurt and might help.

Thank you for sharing this!!
I had mine set on 86* auto and I never felt warm air. I'm assuming you mean that the air in your mask was much too warm for comfort when set at 82* but you had no humidification. Mine at 86* would start out with just comfortable slightly warm air, but an hr/ hrs later be cold and the heating element stone cold. I have 60-62 humidity in the room, maybe that makes the difference.
At least the person you talked to at ResMed told you how to set the manual setting pretty much like my RT was told to set mine.
I hope that setting it up this way helps both of us! I think RT set mine at 6 and 74*. I will try that tonight and keep in mind what you were told.
Thank you again!

Thanks Pugsy!
Never hurts to use Saline spray! I do have it here and I also have neilmed sinus wash and netti-pot that I use. My nasal passages block every night due to allergies (and have for years) so I use generic flonase every night to breathe. Dr's orders. My nose is a little dry, but I never thought of having dry sinus. I've always had sinus issues because they get inflamed and my nose blocks up, often wished I was one who could blow my nose! I have to go get a kenolog shot usually so I assumed that I'd had too much humidity somewhere along the line but I may have been thinking butt-backwards. All of this is still new to me.
Thanks for the suggestion!

Hello from left field. Go with a regular slim-line hose and just work one variable, heating the water and using a hose-cozy to retard rainout. Then switch to the heated hose and try to dial in hose heat once you have established a good water temp. Single variable equations are easier to solve than 2 variable ones.

its seems a nice forum
great discussion


thanks for sharing

Well, tried ResMed's advice and had the same problem.
The manual settings on humidifier was at 6 and the hose 75*. I let it preheat for at least 10 mins before putting the mask and hose on. It felt pretty decent. The air was just warmed just enough to be comfortable. I thought it was going to be fine, but.. Woke up at 3am to cold air, checked the heating element under the water and it was stone cold.. exactly what it did in manual setting since the RT told me to use it. Changing the hose setting to cooler didn't keep it working all night.

Going to try to give ResMed a call as DJL did and see what I'm told.

Clinician at ResMed told me my machine settings are not working properly. If there is no water used, and no condensation on the water tank when you open the humdifier chamber, and you wake up dry at the settings she gave me to try (knowing my room temp and humidity) the machine is the problem. FYI post only.
