S9 hose setting

I ordered a ClimateLine Max Oxy heated hose for my wifes Resmed S9 unit.The oxy means that it has an oxygen port built in.

Her machine came with a non heated hose 15 mm hose with no oxygen port. She was given an adapter that goes between the hose and the S9 that allows the oxygen tube to plug in.
The S9 was set for "ClimateLIne" by the DME -and the new ClimateLine hose is a 19 mm one not a 15 mm like she was using.

I went to reset the machine for the 19 mm hose and the only choices I saw was "ClimateLine" and "Standard". I chose standard thinking that would be for a 19 mm hose.
Is that correct?

By the way, I ordered the heated hose from CPAP.com on the 27th - the day before Thanksgiving - and it arrived on the 29th - the day after Thanksgiving.
Hows that for service!!

I also order the Climate line with the O2 port a few months ago.......I was using the regular Climate line hose before and I had an O2 adapter between the mask end of the hose and my mask, so not using the new hose I can do away with the adapter and use a much shorter O2 hose to just hook into the port provided near the machine end of the hose. As far as the setting you mention, I did not even think about it and installed the new Climate O2 hose in place of the old Climate line.....as you turn the hose to latch it in place you'll see the lcd of the S9 machine indicate that it has detected the Climate line hose and it adjusts to "auto" for the Climate line. I might be wrong, but I think you want to select "Climate" line in the settings so that you can take advantage of the "auto" mode for Climate line where you just select the temperature that you desire and it takes care of the rest for you......if you have "Standard" selected I don't think you'll be able to take full advantage of the Climate line hose........I like mine a bit on the warm side of things so I have 84 degrees set in for the temperature. You have made me curious tho if there is any setting for the larger diameter hose......so now I have to go look through the manual, but I do believe you should use the "Climate line" setting that you mentioned above. If I see anything in the manual about the hose diameter I will report back, but I think the machine doesn't care about that.

I looked at the literature for the S9 and it says if you have a Climateline tube connected you will not see the "Tube" selection in the settings menu, so you might check that on your machine - - I know on my machine when I switched from the regular Climateline to the new O2 Climateline that as soon as I connected the new hose the machine "detected" that I had a Climateline hose attached and the "Tube" selection in the settings menu does not show up at all. Maybe you changed the "Tube" selection before you attached the Climateline hose. In "Auto" mode using the Climateline you can select the temperature that feels most comfortable and it will automatically attempt to maintain that temp and also keep the humidity automatically at approximately 80%. You have the option with the Climateline to set it on Manual and then input both your desired temp and also your desired humidity level - - although I believe most people run it in Auto and let the humidity level then run at approx 80% - - it seems much more simple that way unless you have unusual humidity needs for some reason.

Hope that helps.

I believe the tube selection is for non heated hoses. You have two sizes of non heated hoses and you make your selection of which size your using. As soon as you hook up the climate line it automatically goes to the climate line setting.

My confusion was due to the fact that there are two sizes of Climateline hoses - 15 mm and 19 mm and I did not realize my wife had disconnected her hose when she got up in the morning.

Because the hose was disconnected I thought that with the Climateline hose attached there were two hose choices - Climateline and Standard. I was wrong, with the hose attached there are no tube choices available.

I was also wrong about the choices with the Climateline unattached. The choices with the Climateline tube unattached are Slimline and Standard. That would correspond to 15 mm and 19 mm hoses. Her machine came with a Slimline hose and the machine was set to Slimline.

Since there are no tube choices available with the Climateline hose connected the machine doesn't know if a 15 mm or a 19 mm hose is attached.
There is a choice with unheated hoses and none with heated hoses. That seems odd.

Different size climate tubes does seem strange. And Clay's point about how the machine knows which is which is another good point.

My guess is additional diameter on the Max Oxy is to allow for at least 2 liters per minute of supplimental oxygen, but I'll find out when tech support opens tomorrow and post what they say.

Thanks for starting this thread, very interesting indeed.

The machine can recognize the type hose because of the electrical connection, so you don't need to tell it. There is no need for a choice.

I was able to check in with tech support today regarding the climateline max oxy.

Come to find out, the S9 VPAP Adapt does have a climateline max oxy selection for tube type. The reason for the larger diameter is to provide more interior volume and thereby less pressure the oxygen has to "push" against. At higher PAP pressures, oxygen flow can be impeded with the thinner tubing.

Hope that helps for those who are interested.

that's interesting and makes a lot of sense - before I got the Max O2 line I was using the standard (slimline) Climateline hose and getting the O2 into the system just between the hose end and mask via an adapter. Was a bit of a pain as I had to tape the O2 line to my hose so they would be in one bundle and easier to handle with turning over at night. The Max O2 line solved that problem so now I can just use a short 4 foot O2 line and attach it to the Max connector at the back of the machine. I am using a S9 Auto Set so when I attach either of the Climateline hoses the machine detects it and the Setting for Tube selection will disappear because it is for non-climateline hoses. So I figured as far as the S9 machine itself is concerned it really doesn't matter which of the two approved Climateline hoses are attached. I will bet you that newer software on future versions of the S9 will account for the fact that there is now a larger diameter Climateline and we will see a new setting in the menu to select one of the two differnet diameter Climateline hoses.
