PRSystem One Heated Tube Humidifier numbers to temperature

[squid13]

The numbers on the heated humidifier are 1 to 5. I read somewhere where the numbers are a certain temperature like 5 is 90 degrees and 3 would be 80 degrees. Does anyone have a reference to such a written document.

Which humidifier?

The 60 series?
This humidifier offers three levels of humidification (70, 80 or 90 percent) and the heated tube has five levels of temperature available, ranging from 4 to 16 degrees above the room temperature. These two features work together to deliver the optimum humidification level at the mask.

The 50 series? No...the number choices on the humidifier aren't degrees per se...just levels of humidity delivered. Of course more heat is needed to get higher levels of humidity.
This is the guideline for settings on the 50 series machine.

This initially looks like setting 5 delivers less humidity than setting one....but what it means is if your ambient room humidity is so and so...this is the setting you would use to attain optimal humidity.
So if you live in a rain forest...you already have high humidity and you probably would want to use a setting of 1.
If you live in an area with ambient humidity around 40-50%...you might want a lot more humidity and thus you would choose 5.
This little spec causes lots of confusion.

Setting 1 = 80-90%
Setting 2 = 70-80%
Setting 3 = 60-70%
Setting 4 = 50-60%
Setting 5 = 40-50%

I was asking about the 60 series heated tube humidifier on how you control the temperature you want and the humidity you want. If I wanted 8 degrees above room temperature what number would that be?

If I do my math correctly assuming that 16 degrees above room temp is the highest setting of 5 and assuming there are 4 degree segments..
But that doesn't make sense because one would assume that 1 would give 4 degrees above room humidity but maybe I am assuming wrong. I have never seen an actual temp correlation in this format from Respironics
If we work up from a setting of 1...assuming that one is 4 degrees..there's not enough 4 degree segments to get to 16.
So I am also confused.
1....would be 0 degrees above room temp but that makes no sense
2....would be 4 degrees above room temp
3....would be 8 degrees above room temp
4....would be 12 degrees above room temp
5....would be 16 degrees above room temp

makes me wonder if they aren't in 4 degree segments after initial setting and assume 5 setting gives 16 degrees above
1...would be 4 degrees above room temp
2...would be ?
3...would be ?
4...would be ?
5...would be 16 degrees

So I don't know exactly. Hadn't really thought that much about it and sure haven't seen anything other than the statement about 4 to 16 degrees above statement but have never seen anything that show what a setting offers in actual increments.

I don't have any way to try to measure the hose delivered temperature either.

I agree with you on this, I would assume automatically that 1 would be the lowest setting and 5 would be the highest not the other way around. So if the humidity is ass backwards would one be 16 degrees and 5 be 4 degrees.

I have the 50 series (PR S1 750) and I live in the desert of PHX. Now that summer is starting for us and we are in the 90's and 100's (and soon to be 110+) with super low humidity. My current setting is #3. So really, I should maybe try a 2 or 1 for more humidity?

No....you are falling for the ass backwards presentation of that setting thing.

The % of humidity that you see shown by a setting number...is what your ambient humidity is...not what you want delivered to your mask.

If you want more humidity delivered..you have to increase the number on the humidifier setting.

The way they presented this bit of information....horribly confusing. If you go down to 1 or 2...your nasal mucosa will get less added moisture. Trust me...been there, done that and for someone whose nose needs lots of water it give ugly results.

What they are saying with this guide and let's use Setting of 4 as an example.
If your ambient humidity is 50 to 60% and you want to have delivery of optimal humidity (and they don't tell us what optimal is but it normally is considered to be around 80%) you would choose 4 as the setting.
The drier your ambient humidity...the higher number you need to select on the machine in an effort to try to maintain a constant level of optimal humidity.

So these % numbers refer to the humidity level in your house....not what is going to be delivered.

Setting 1 = 80-90%
Setting 2 = 70-80%
Setting 3 = 60-70%
Setting 4 = 50-60%
Setting 5 = 40-50%

Man....I SUCK at math word problems!!

[squid13]

Why couldn't they have built a heated humidifier and tube like what ResMed uses, it would of make life a whole lot simpler. All we need to do now is figure that temperature part out. I guess it goes along with ever you select for humidity to bring it up to that point. If you select 4 your heat for tube is also 4.

You know they had to be "different". The only reason they even came up with it was to compete with the ClimateLine. But they couldn't be seen "copying" the Climateline. That just is not something they want to do.

In a way this way has its advantages...in a way disadvantages.
It would have been nice if they had explained more efficiently how it worked instead of the ass backwards thing.
First time I looked at that I thought WTF...that makes no sense whatsoever.
If you look at it closely...what it is..is comparable to the ClimateLine in patient mode where temp and humidity choice is independently available as opposed to Auto giving the same 80% no matter what temp.
Piss poor choice of wording on how to setup up the machines though.

I understand the hose temp now but what is the humidity level for? 1-3? Wish my DME was more educated on the products they sell.

This humidifier offers three levels of humidification (70, 80 or 90 percent)
So at these settings
1....70%
2....80%
3....90%

[cpaptony]

So forgive my ignorance. Let's say for example today in Salina Kansas it is 60% humid
I'd use setting 3 for the hose temp
An the humid level setting should be 1?
Just trying to understand sorry.

Setting 1 = 80-90%
Setting 2 = 70-80%
Setting 3 = 60-70%
Setting 4 = 50-60%
Setting 5 = 40-50%

But if your ambient humidity is 80-90% and the "optimal" target is 80%, wouldn't setting 1 mean no humidification?

Also, it turns out you can get a heated humidifier without the heated tube on the 60 series. They brought me the "wrong" version (which works with the 60 series blower) and I want to figure out how to translate a setting of "3" to the new humidification settings.

It sounds like the old (non-heated-tube) style is basically a fixed boost over ambient humidity, whereas the new version is a fixed target humidity?

What happens if you use a non-heated hose (say, a plain backup) on the heated-tube humidifier? Will the humidifier still work?

This is one of the worst usability flaws with the PR1. Why the engineers did this is beyond me. The owners' manual is not even clear about the settings, unfortunately. The higher the number the greater the humidity and/or the heated hose temp -- not the other way around.

If there was ever a need for a firmware update that would simply show temps or humidity percentages on the LCD display, this sure is it.

From cpap.com: "The PR System One 60 Series Heated Tube Humidifier with Heated Tube optimizes air stream humidification and reduces rainout while guarding against machine water damage. The humidifier considers room air temperature along with the airflow of the machine to adjust the humidification level. The Heated Tube adjusts in concert with the humidifier to maximum comfort, which helps to increase the success of the therapy.

"This humidifier offers three levels of humidification (70, 80 or 90 percent) and the heated tube has five levels of temperature available, ranging from 4 to 16 degrees above the room temperature. These two features work together to deliver the optimum humidification level at the mask."

So with the heated tube in use, the knob adjusts the heated tube temps. The humidity, however, is set separately, on the display, from 1 to 3. (70%, 80% or 90% humidity). Simple huh.....
