S9 - H5I humidifier question

My 2nd night with S9. So far so good. Great results. My AHI is even better with S9. 0.1 and 0.2 - usually 2-5.
Feel better, continuous sleep for 7 hours 2 nights in a row.

What is puzzling is the H5i behavior. It is never warm, there is not even water droplet in H5I.
I tried to warm it up before sleeping through the menu. It works but no warmth. water level is still 100%.

FYI: my room humidity is above 50%, the temperature around 20 Celcius or 68 Fahrenheit.

My PR System One humidifier is always warm in the morning and there are water droplets within the humidifier - one night normally took 1/4 of the water, water level drop to 3/4 of max

is this normal?

WIth the normal slimline tubing, the humidifier won't get warm until a setting of around 3.5.

I use 4.5, many use 5, but I get rainout at 5, and none at 4.5.

thank you for your info.

Now at least I am not so worried. I thought that I get a defective humidifier.
Since I bought from an on-line personal seller, I do not have any warranty, a defective humidifier will cost me lots of money

That's great news Cpapernewbie!

I just bought my S9 Autoset today and can't wait to try it out. I'm hoping to get the same results. I tried the fixed S9 about a week and my Apneas got worse! I felt really bad in the morning. Good to read that your Apneas was so low.

Will let you know how I experienced mine.

Happy nights

I too have problems with fixed pressure CPAP. Spent more than 1 year on an auto set with a fixed pressure. It was good in the beginning weeks but then I got very dry and painful mouth and throat.

I blamed this on leaks and bought chinstraps and tried taping and everything that people talked about - in the end after 1 year i switch back to auto and I need lower pressure and have better leaks stats.

Contrary to what i read here that doctors said straight CPAP is best for you, an auto is much more comfortable for me.

So not everything you read in this forum will be applicable to you - an auto give you more options and some people need an auto to succeed in CPAP treatment

I've had my S9 w/H5i humidifier for about 2 weeks now (used a M-Series APAP before that for about 3 years or so).

I've turned my humidifier all the way up to 6.0 and still don't get rainout. I also use the preheat function and it seems that the pad on the bottom of the humidifier tank is never much more than above room temperature. The odd thing is though that the level of water in the tank actually DOES go down from the MAX line to the bottom line on the depth gage. This means that I must be getting humidity out of it, but I'm worried that it is just passive humidity and the water usage is due to the climate here.

The thing is, we're going on our annual camping trip at the end of July here in the mountains, and it gets quite chilly at altitude in the mountains at night. Just don't want to be stuck with cold air going up my nose. I do plan to buy the heated hose before then (there is electricity at the camp site), so that should help, but would be good to know that the darn humidifier actually works.

If it's emptying the tank then it is definitely working. It takes me 2-3 nights to empty the tank on a setting of 4.5. However, if it is not heating up at all if you run the preheat cycle you might want to investigate that. Someone else had this trouble but ended up saying they were running the wrong preheat. I honestly can't say I know what they means because I don't have the climate hose and I didn't investigate it to see what other preheat options there are. Anyway, that might be something to look into.

ooops, forgot to mention that my humidifier setting is 2

No wonder!

oh oh oh yes, that is right...

the settings on the s9 for humidity are nothing like the system one..

I could put the old machine on two and get tons of humidity, true, with the new s9 you wont see nearly a drop unless you crank it
up to 3.5..

so they are very different in that respect..

dont forget to turn the nob to the water droplet to kick start it for warming up.. it will say three second warm up, and you press the
button for three seconds.. be ready for bed in fifteen minutes!

sweet dreams!

Just some feedback on my 1st night back on the S9 Autoset. WOW, WOW, WOW!!!!!
I feel fantastic this morning better than I have in such a looooong time!
Slept 7.2 hours straight with AHI of 0.2 Isn't that just GREAT!!! I was also sceptical to buy it after all the comments on the machine, but boy for me it defnitely works!
Just a question, I experienced the same problem with the humidifier. It didn't feel like it warmed up and I did the warming up thing Elena88 explained before bed. Have you figured yours out yet? The knob was turned to 20 degrees C.

hey we are getting similar AHI. My 3rd night, still the consistent 7hrs+ - no wake up. This is really great, with PR System One I usually have 1 wake up in the middle of the night/morning around 3 AM and then spent the time on my laptop not being able to sleep for 1-2 hours. Now it is straight sleep until 7

My humidifier still not warmed up eventhough last night was a cold one.

One thing I hate in this S9 is having to force the CPAP off by jacking off the power cable - this S9 continuing blowing feature after usage is a bad feature for me. Why waste energy for nothing?

Just press the power button for 3 seconds and it will power down.

The need to turn off the machine is a result ot the SmartStart setting. If SmartStart is set to "PATIENT" in the Clinical Setup menu then the machine starts when you put on the mask and turns off after you take it off. This feature was the default on my old Autoset T. Thus I am left to believe that this setting has to do with comfort and not medical necessity.

ResMed has settings in the Clinican's menu that allow the patient access to the EPR level, SmartStart feature, and Climate Control features. The problem is that the default is to deny them to the patient and apparently, as in my case, the RT either do not decide to make them available to the patient or do not discuss them with the patient. So apparently if your doctor does not mention them on the prescription you run the risk of not knowing about these options. This is a great way to lower the compliance rate.

Good to hear you are getting on well with the S9. As you have used both the System One and the S9 your decision on which machine is best for you will be of interest to many people.

I know the humidification systems are different in terms of number of sensors etc but my guess would be that your ambient humidity is already high enough and the machine has decided no to add any more.

Uncle_Bob:

thank you very much for the solution to that continuous blower blowing after the CAP usage. That 3 sec button pish work great and now i do not have to jack off the cable off the power bar.

Yes, I have used both the 3 generation of Respironics CAP
1. the Pro tank - first use and a big failure - set me off the CPAP for 6 months)
2. The Auto tank - first success
3. The M series auto C-Flex
4. The M series auto A-Flex
5. The M series Plus (temporary buy from Craiglist to replace the auto)
6. The m series A-Flex replacement
7. The PR series One
and now the S9

I know pretty sure which are the good ones and the bad ones
