Longer hoses
#1
It appears that longer (than the 'standard' 6' /1.8m) tubes/hoses are reasonably common in the USA, at least based on my perusal of ebay & online CPAP suppliers there. 

"Great" thought I, "an 8' hose is just what I need in our off road camper"

Well, not only is anything other than the standard 6' hose length uncommon is Australia, it is as rare as hen's teeth. I spent at least a couple of hours phoning a plethora of suppliers, both local to me & all around the country only to be consistently met with apologies & the telephone equivalent of blank stares.

Seems that Australians don't need/want/use anthing other than 6'.

So Amazon got my money & I now have a 3 pack of hoses on their way to me from the USA. I'm keeping my fingers crossed that they get here before the end of the month so I can use one for a 4 day camping trip we have planned.

I am amazed that they are unavailable downunder.

Just out of interest, given the machine they will be connected to (a Devilbiss Intellipap 2) has settings for different length & diameter hoses, are there generally any 'issues' with longer hoses I should be aware of?  Hopefully my fleecy hose wrap will also arrive in time for the upcoming trip.

I think there could be a slight decrease of pressure over distance, based on what I've been skimming at this site:  https://www.physicsforums.com/threads/ca...op.375348/

I'm not sure it would be enough to be a problem. One of the more physics-knowledgeable folks may know.

Found a better explanation [link to commercial website removed - see below]

"The longer the hose the greater the pressure loss end to end.
10' hoses are generally considered to be the limit.
Last year I ran several tests where I measured pressure loss over a 6', 10' & 12' (2 x 6') hoses at different pressures.
The drop is about 1 CMS per 6' at 10 CMS pressure (while in use (breathing)). "

Based on that description, you are adding 2 feet, so a possible pressure drop could be about 1/3 cm if you're set at 10 cm of presure.
