Why use two hoses?

Post by DJL » Mon Aug 12, 2013 10:19 pm

Just saw my sleep doctor and mentioned that the temperature of my H5i/S9 climate hose was too warm om my face when on was using auto mode at 80 degrees. I need it high to get enough humidity. And so I told him that I was trying to use the manual mode on the humidifier and tube.
In the past he had recommended that I use plenty of humidity due to past sinus surgery. I told him of my concerns of rain out if I went high on the humidifier (at present set on 5) and too low on the hose (set on 74 degrees).
He said to add another 6 foot plus hose to my existing climate hose, would this arrangement not just increase the chance of rain out, because the humidity would just cool quicker in the second hose. I forgot to ask him the logic behind his suggestion because I was thinking of other things at the time.

It doesn't make sense to me. Maybe someone else can figure that one out.

I do recall reading several studies dealing with room temperature and obstructive events. Too warm was bad. Good stuff near 72 to 74 degrees. Bad stuff at higher or much lower.

I do not understand how a cool hose warm hose arrangement could be made to deleiver high humidity cool air with no rainout.

Have a great week!

I think there is an 8' or 10' hose you can buy, but I think that is the max. Hooking 2 hoses together is something I've never heard of and I believe at that length you would not get your required pressure at the mask end.

Well... with the added length the rain out would most likely just pool in the hose. and it would very likely happen in the unheated hose providing all the other factors that cause rain out are present...higher humidity delivered and a cold bedroom.

It will most likely reduce the perceived temperature of the air getting to your face but it is a recipe for rain out in the highest degree.

People do use 2 of the 6 ft hoses attached together...or 8 or 10 foot hoses but that isn't possible for you since you are using the ClimateLine. I do think I remember that 12 foot is the max that is suggested because above that there is some question as to pressure being delivered at the end.
