What is the life span of my mother, 84 -yr. old, with end-stage emphysema, with serious memory loss, no longer given oxygen or nebulizer treatment since it no longer is effective, down 40 lbs. in the past 10 years, must live in a nursing home for 24/7 supervision, no longer can stand without assistance, has not been able to walk for the past one year? Does my mother have any way to make her feel better, even for just a few minutes?
