My mom was diagnosed with severe COPD recently. She's been in and out of hospitals and nursing home. She's basically been homeless for many months/years (sleeps on someone's couch and lives with 4 other adults and 5 dogs in a 1000 sft home). She's currently on oxygen 100% of the time and will be the rest of her life. She'd like to go back to work but needs a portable, lightweight oxygen tank. Unfortunately it appears insurance doesn't cover. She can't go back to work and try to get life back on track without this. Anyway you can help me/guide so I can help her get back on her feet?
