They came and took away my oxygen concentrator, and also almost a dozen small tanks that were clustered in the other room. In their place, they left a new oxygen concentrator—one that I think puts out a flow closer to the advertised rate—and a Dalek-like machine that sits on top, which refills tanks while I sleep. Now, instead of being limited to the ten smallish tanks that I was allowed per month, I have only two, but I can use them as fast as I can fill them.
This is for going out, of course, especially for dog walks. I’ve learned that my clever Inogen portable concentrator (POC) is fine for going out to the store or whatever, or just knocking about where exertion is low. But when it gets more aerobic, like dog-walking, it just can’t keep up with my needs as well as a small tank in a backpack. I believe this is because the POC gives the O2 in little pulses when I inhale, which is less assistance than a tank on continuous flow. The duration of a tank is shorter, of course, but all I need is 30-40 minutes to walk the dogs, and for that it’s better.
The new machine has a different and no less annoying continuous drone from the old one, and since it’s near where Allysen works all day, I spent that afternoon putting together some sound baffling to try to cut the decibels. That part is still a work in progress.
