My Mom is 90 and has moderate dementia. She lives at home alone. She had asymptomatic Covid two weeks ago and was hospitalized. The doctors say she needs a pacemaker. She doesn’t seem to understand what is involved despite multiple explanations. She has a DNR and doesn’t want to prolong her life and is anti intervention. This is complicated as I live in a different country from her, am an only child, and she had very little family. What should we do?
