Fund for Father's Portable Oxygen Need

My father was just recently diagnosed with cancer unsuspectingly. He never smoked, and was never around people that do smoke. The changes to our everyday life have been devastating. Simply getting around and moving like he used to is an obstacle, especially when having to roll around an oxygen tank wherever he goes.

I would like to raise at least part of the money for a portable oxygen concentrator, to aid him in getting around out of the house. Any donations would be appreciated. I just want my father to be able to move more easily.
