We're re-evaluating the system we now have, which consists of several E (large size) tanks and 2 D (smaller) refillable tanks. The D tanks last for 2 hours so they aren't very practical.
(1) Has anyone ever used a portable concentrator?
I've done some research on the portable concentrators (not portable tanks) but haven't yet gotten enough information, especially on pricing, to make a decision. I expect that Medicare may balk at paying for them, but if they're more practical and usable, a purchase might be the best solution.
They seem to be so much more practical as they function as a concentrator rather than a tank with filled oxygen.
I understand they're battery operated; if you've used one does it use lithium ion batteries? The research I've done thus far doesn't address the type of battery, which is important in part for safety issues.
Have you had problems with them? Do they produce oxygen reliably? Are they cumbersome - even a less than 5 pound tank can be too heavy for an older person.
(2) Does your oxygen supplier require you to fill the D tanks on your own time and cost? I was advised yesterday that we're now expected to use a refill machine which requires 4 hours to fill a 2 hour tank.
(3) Do you have pulse operated cannulas? What criteria had to be met to get them? I do understand that they're not suitable for everyone.
Any thoughts and suggestions would be appreciated.
