I have 2 kids, teenagers. I can't be without the oxygen even lying down. I have these tanks which I must fill myself from a compressor. The company only gave me 2 tanks and while initially that was good for about 6 hours, now I am requiring higher flows and it lasts only 2-3 hours. So when I would go out, I would slow the flow down to save oxygen but it was painful. The company brought me more tanks on Monday. But I think I might have to go to the much bigger tank that lasts 7-8 hours. My day at the onc today including traffic time was 6 hours and again, I was panicked that I would run out and was curtailing the use. Not a good thing since my oxygen sats are very low. It's just that the big tanks are so heavy and bulky but I may not have a choice.

Eleanor,
If you don't mind could you send me your e mail. I have a lot more questions about the oxygen. You have some good suggestions.
