Barbara deserves praise and admiration for having the courage and the support of a strong family to realize that life is a continuum and it has a logical and inevitable end. Some families are SO selfish in that they will not allow a person to peacefully pass from the present to the future, forcing them to suffer the indignities of involuntary medical abuse while "saving" them from the inevitable in end of life scenarios.
Ever been to a Code Blue event where clothes are ripped off the 98 year old little old lady? the patient is tossed about like a dummy as tubes are inserted, electrodes placed, electrocution (of a sort) is done, physical assault of chest compressions and more.
As a former Critical Care RN, I often felt terrible in participating in these barbaric rituals of life extension, to Hell with cost, comfort or quality of life. Families need end of life counseling when a family member approaches extremis situations so as to avoid the torture of that very ill family member and any others in the family that cannot let go.
