I have just been put on 24-7 oxygen and would appreciate any help you can give. I have 50 feet of tubing I'm attached to, which I'm trying to figure out some way to roll to have it so it isn't always in the way. I'm thinking of using velcro somehow . If any of you have had to deal with this, do you have any suggestion? I am also trying to figure out how I'm going to use the portable tank, which is a large one, because my daughter is in a wheelchair when we are out. The tank is too tall to fit in the bag on the wheelchair. This is all new to me so I really could use some help. Thank you for any help. Blessings to all. Kathryn
