I'm wincing a bit at the term Euthanasia, when I think people mean do not attempt cardiopulmonary resuscitation. It's an important distinction folks!
But I agree with the sentiment. "What matters to me" conversations about peoples preferences for their care at the end of their lives are best when they happen ahead of time, allowing people to discuss their choices and preferences with their friends and family.
Unfortunately, most of those choices, particularly with regard to place of death and people present, cannot be fulfilled at the current time and as I have posted previously on these threads, I am grateful that I was allowed to say goodbye to my own DM.
it is legal for a medical practitioner to determine that it would be medically futile to attempt to resuscitate someone who would be unlikely to recover or would have an extremely poor quality of life if they did survive resuscitation, although this should always be discussed with the patient and family when possible. I have been disturbed by what appears to be a wholesale DNACPR approach to some care home residents though. Even in the saddest, most difficult circumstances, it should always be a decision about an individual.
