My mother has COPD. She is on oxygen most of the time. We moved her in with us two years ago. At that point she had already had an oxygen concentrator for a couple of years. She got it when I lived out of town. Well, I just stumbled over information about it having a filter that is supposed to be cleaned once a week. I should have thought of that, but this whole caretaker thing is often overwhelming and I'm always playing catch-up since my mother is not a fountain of information. Even my little sister, who is often the one who sorts out care issues (long distance), didn't realize about the filter. I feel like an idiot. The oxygen people never told me either. Now I'm thinking that the concentrator has been working harder, wearing out faster, and being less efficient because I never realized it needed its filter cleaned. Who knows where the original product info is. Mom used to keep product info for appliances all in the same place, but the concentrator info is not in that pile, and I don't recall seeing it when we moved her out of her place and into ours.
So this morning I'm trying to stop kicking myself because that doesn't really help, and as soon as my mother gets up I'm going to drag that concentrator out of her room and look it over. And I'll have to call the oxygen people because I don't think it has been serviced in the last couple of years. Sigh.
