ResMed S9 >>> Humidifier Problems

True, if the heating plate on the humidifier is off or not working, the air coming through the machine, will be room temperature. If the humidifier is operational, the water in the reservoir, will be heated, thus heating the air as it leaves the machine. That is what happened to me, the humidifier failed, resulting in cold air, coming through the machine into my sinus cavity. I immediately checked the heating plate and it was stone cold. When I previously changed out my humidifier at the VA, they told me that they have a high incidence of the humidifier for the ResMed S9, being bad.

the modern machines use smart humidifiers, they have humistats that measure the amount of moisture that is in the room air and adapt to that. if the air in your room wasn't dry, then the humidifer will add very little, or no extra moisture. they adapt on an ongoing basis. unless you measured the heating plate with a thermometer, all you know is that it wasn't hot to the touch, but that could be most any temp from room temp up to near body temp, all will feel cold to you.

many people have mistakenly thought that the humidifier in a modern machine has failed, and been wrong, simply because they didn't realize the humidifiers aren't just dumb "heat water" things anymore.

I have had the ResMed 9 and had nothing but problems with it. The water tank leaked, so I notified the place where I bought it and they said they replaced it with a new one. That leaked and the place where I bought it from said the machine checks out fine and if I send it back to ResMed, I will have to pay for the repair. I became weak and my legs got knots in them from lack of oxygen. I bought another machine and within two weeks am much better-not one hundred percent. The sleep place has been giving me the run around; told me I need a new sleep study test! and they cannot find my old records or prescription. I went to another source and the records will be sent within ten days!

Strange. Why wasn't the repair covered by ResMed's two year warranty ? From where was it leaking ? Did you show them the leaks via photographs or demonstration ? During the warranty, you or the vendor can send it to ResMed.

Which entity indicated you need a new study ? What evidence do you have that you lacked oxygen ? Records sent within ten days from where to where ?

The CPAP machine itself cannot leak. If the humidifier was leaking it was the plastic tub. If for some reason the humidifier itself was returned, you could use the CPAP machine without the humidifier so you will not get leg knots(?)

If heater fails, the air will will be lower than rooms temperature by some amount up to 20 degrees F depending on the room humidity. If the room humidity were say 35%, then I would guess that the air going to the mask would be something like like 10 degrees lower than room temp. ( I am too lazy to calculate the exact amount). This temp change is due to the evaporation of the water. This is like the cooling effect of sweating.

I have had the same issues from day one with mine, It starts out to be working then it stops heating and tank is cool and it drys out my nose and mouth and i have to no avail get them to under stand the thing does not work then it wont document that i have used it and they say its because i didnt use it when i know that i did in order for my ins to pay for the thing i had to wear it at least 4 hrs a day and the lady said if i was not going to wear it turn it on a leave it running for 4 hrs for ins to pay for it, What the heck, I told her it was not working and then they sold me a mouth strap and said i must be breathing out my mouth at night so that is why my mouth was dry and nose . But i told her that still did not fix the fact the water take was cold and not warm, Well the strap to hold my mouth closed but i still woke up with dry eyes and nose and mouth. Now i have been seeing that this RES Med S9 has issues and has caused me issues and a lot of others a lot of issues here from reading what others have wrote. The people i got this Res Med from made me feel it was all in my head and nothing was wrong with this Res Med S9 It caused me mush distress and i found my self taking it off through the night and got to wear i could not breath good with it like pressure air flow was not right, They made me feel like i was me and not the Res Med , That nothing was wrong with it , Well i stopped using it and suffered a stroke. Now i have a Res Med S9 i can not use and my ins will not pay for another one. This company should owe up the the fact that they have some that do not work and give back there money are make it right by given them one that works.

A medical equipment repair tech here. I'm looking at another S9 at the moment with the usual reported problems; cuts off and/or humidifier in-op. This one is reported to "cuts off after a few minutes" and "humidifier not heating" Of course I can't duplicate either problem, it's been running for 24hrs straight, and there isn't anything in the error log to support either issue. The last code is 631 and it was 9 months ago.

I now know how a car mechanic feels when a car acts up but they can't duplicate the problem and there isn't any error codes. They feel bad because they can't fix the problem they can't duplicate. You might as well throw a hammer at it and replace what it hits. Then they cringe when the car come back a month or two later.

At least another popular manufacture's error codes are service tech friendly and tell you what needs replaced. If I have a "cuts off issue" there will be a related error code recorded. 99.99999% of the time it correct and fixes the issue.

I keep a cheap little hygrometer next to my machine.
It tells me the ambient humidity.
Then I know why the tank is still mostly full, or nearly dry.
These things are usually more reliable than we think--or wish, if that's the case.
