Yeah, the concentrator does not supply the level of the tanks we know. That came up during the last delivery of the tanks. Sometimes if more than normal get used we make the short trip to the office and pick it up. Can't do that now. We will be watching it from now on. A lot of this is still new to us.Yep, they had a back up for my mother in case of power outages. I think her room air concentrator had a battery back up though, plus at the time I was living in town so if there was a power outage all I had to do was call and ask for priority power restoration due to her being on O2. Never had to do that.
When she was worsening, they brought in one of these humongous tanks for a back up as the concentrator wouldn't handle high levels of 02 that require a rebreather mask. I was glad they did as she wound up needing it.
Shame the company that supplies her 02 didn't check with you knowing a holiday was on tap. The one I used did.
