Operation: get an oxygen tank

Carina is on 24/7 oxygen. She goes through at least one tank a day. My sister and brother in laws home is filled with oxygen tanks. I’m raising money for them so they can have their own purse sized travel oxygen tank. This would provide them better transpiration wherever they go with Carina: restaurants, grocery shopping, airplane, car rides....anything!  We appreciated and loved every single donation when she was born, Her fight isn’t over. Please help. Thank you!
