Nose Cannula 02 Hard vs Soft

Well a few months back I noticed when changing my 02 hoses that my
nose cannula insert said "7' hard". Hmm I thought, wonder if there is soft, more comfortable maybe. Contacted my oxygen supplier and asked the question if there was such a thing as a soft cannula and their answer was YES! . Asked why I was never advised of this, or if my insurance would not pay for them? They just give teh basic starter kit and people keep ordering the same thing. Well, I curious so asked about the 7ft thing and if there was other sizes. Yes, there is 7 and 4 ft

My choice of size was immediately 4 foot length. Why this, the 7 foot was to long for the POC and then for the home unit which only does 50 feet of hose for the proper use (amount of 02 delivered) firgured the shorter hose would be better for that simple reason, you know 54feet total instead of 57.

Which cannula is better, Well I can not decide, but can tell you what I am doing now.

AS for with my home compressor, I take turns as I switch / change to a "clean" one every two weeks, unless I am sick, them I change then. Why? The hard one holds the neck noose thing tighter, but hard like plastic and wears on the ears. Soft one, small in diameter, feels like a soft rubber, stretches easier if you get caught up on something or step on it, does not pull as hard it seems. Each one tend to make a groove like feeling behind my ears over time, so with switching them because of the diameter sizes being different and the weight of each, this gives my ears feelings, gives them a break.

For outside use, soft only. The weight seems somewhat less, and during the cold it does not get as sift and unmanageable like the hard hose does, easier to shove the hole thing up under the clothes.

That is all I have for now, hope someone can use this observation / experiment of mine to see what you might like better.

Oh and the cost / co-pay was the same for either.
