Connecting two 6 foot tubes

Hello All,

I was wondering if anyone out there has connected two six foot tubes to make a 12 foot tube. If so what coupling did you use, where did you get it, and how does it work (ie. leak rates).

Here's the part you would need to do that;

I would worry that you wouldn't get the proper pressure through so much hose.

You can get 10 foot hoses, 10 foot is the max you are suppose to use, some worry about the detection of events being masked using
AUTO Cpap with longer hoses, I haven't had a peoblem with 10 foot.

The length of the hose, the size of the H/H & how much water is in it and the type of mask all have a very noticable effect on the pressure that appears at the users nose/mouth.

Early Autos were intolerant of some masks (mainly f/f masks & also today's hybrid would not have worked back in the early 2000s.

I am doing some tests at the moment that I plan to do mpeg videos of, showing that most machines with a 6ft hose, lose approx 1 cms of pressure between the xpap air out point and the face mask.

The only xPAPs that don't exhibit this loss are the ones with seperate (internal or external) pressure sensing air lines such as the PB330, PB42x, & AutosetCS.

Some bilevel machines are showing losses over 1 cms on the ipap setting where it is on the highish side (around 13+ (VPAP III models & all Bipaps).

That's one thing about using the software to control your treatment, if you have a loss in treatment pressure, due to something you added, you set your pressure by what works best for your treatment.

Without the software you would end up undertreating yourself. Jim

I would think that using a 10 footer would not be a problem especially using a Auto CPAP machine as it wil adjust for any pressure lost right???

A AUTO works of sound and breathing patterns, the longer the hose the harder it is for the machine to see the readings it needs, the pressure changes get dampened by the length they have to travel, like waves in a pool. Jim

CPAP provides one pressure that not supposed to change, so no feedback is needed except pressure.

auto CPAP would correct for it right
