Oxygen for Shane

This is my brother,  Shane. He has Pulmonary fibrosis. Pulmonary fibrosis (PF) is a chronic and progressive lung disease where the air sac in the lungs (alveoli) becomes scarred and stiff making it difficult to breathe and get enough oxygen into the bloodstream. He has been homebound for the past few months because he has to be on oxygen 24/7.  His health has forced him into early retirement, cutting his income. His health insurance won't pay for the portable oxygen system he needs in order to to mobile. Because of his spinal injury, his gait is not able to support him with the heavy wheeled oxygen tank he has, so he is unable to leave home. Being homebound affects a person's  mental, emotional and physical health. Please help me get my brother out and about by contributing to the cost of an Inogen One G3 Portable Oxygen Concentrator, which would clip to his belt, providing him the mobility and freedom he needs.
