My dad has the Inogen G5. Dad has found it to be a real friend allowing him to contiue to do activities away from the house. His pulmonologist did suggested that he use the shoulder strap, rather than the hand strap, to put less strain on his breathing. The doctor suggested that a backpack would be even better. The Inogen one is over $100, which I think is ridiculous even though he could afford it. So, being the cheap b**ch that I am, I found a picture of one online and using my sewing skills, made him one. The materials cost me about $20.Not yet, I’ve had difficulty driving due to shortness of breath. I had oxygen tanks, but my disability due to my back pain (due to cracked vertebrae, spinal stenosis, and arthritis) made it very hard to use a cane or Walker and tote a heavy tank. But a friend bought me an Inogen G5 oxygen concentrator, much smaller and lighter weight. It arrived yesterday. I plan on getting out and driving my Outer Banks to the pharmacy tomorrow. They have a drive through window, so I won’t have to go in. Even with pain meds, I can only walk about 15-20 feet before my back starts screaming at me and I have to sit down or fall. I had to switch doctors a few months ago, because he moved to the end of a long corridor in the physician’s building. I could barely make it from the parking lot to his old office, which was just inside the building’s door. So, depending on how much walking is needed to attend a support group, it may or may not be feasible for me to attend. But thanks for asking. It’s not something that I had thought of. I’m still kind of in shock from the diagnosis.
