I just got the Airsense A10 autoset, but in the past have used fixed CPAP. I route my tubing over the back of the headboard to keep it from pulling, so have always used 2 six foot standard tubing coupled together.
With the new APAP unit, I wonder if using the tubing extension (std tube 1st, then slimline tube) will cause a problem with the pressure setting/sensing aspect of the unit.
Also, has anyone heard of a climateline tubing longer than the 6 ft standard, or if it can be extended?
Thanks in advance,
I think the official answer is "no."
I suspect it would mostly cause problems with EPR, bilevel, distinguishing centrals, and maintaining a precise pressure at the mask. I suspect the problems would be minor.
I don't think it would miss apneas, but it might not detect which type.
Try it and see how it works.
I don't think there's a longer heated hose option.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
There is a 3 meter standard 22mm hose available. And there is a setting for that hose.
I think two different diameter hoses more that a slight issue. The reflection boundary can wreak havoc on the FOT wavefront as far as differentiating among types of apnea. In straight CPAP mode -- perhaps not such a big deal; but in Auto, it may result in inappropriate pressure increase response.
If you must have 4 meters (~12 ft) better to splice (couple) two 22mm hoses.
I am a multi-discipline engineer with many years in flow dynamics.
Can you not make the 3 meter hose work? I use a 2 meter; and still thread it through a bracket in a small wall shelf.
