Another medic.
I had vicious and ugly arguments with my aunt & grandfather about DNACPR for my Gran and then repeated them all with my aunt when my Grandfather was dying.
My Gran was especially crazy - she was dying of renal failure. She had already refused dialysis herself. We knew without dialysis she was going to die, she was confused as a result of the renal failure hence no longer being asked to make her own decisions and the doctors and I (I have ICU training) reiterated that with her history she wouldn't be accepted to ICU. There was no point to attempting resuscitating her - she had a condition that she had declined treatment for herself...if by some miracle CPR temporarily worked she would only have arrested again. Made me so angry that my supposedly "educated" relatives couldn't see how ridiculous their view point was.
Fortunately in both cases the medical staff didn't allow my family members to prioritize their needs (after all 94year olds with renal failure are going to live forever) over the person who was dying.
This whole situation was hideous for me as I was still grieving for my own mother who had died (with a DNACPR in place!) 6months previously. I was angry that I had less than half of the time with her that my aunt had enjoyed with her Mother yet at the end my siblings, Dad and I all supported /and in some cases argued that she should not be admitted to ITU or have CPR.
This was an incredibly painful decision to make and despite being "in the business" and having had DNACPR, refusal for ICU and end of life chats lots of times it was still awful. However resuscitation & ICU was not what my Mother would have wanted and was in any event totally pointless. She was dying of an irreversible disease process..
However, we found ourselves in the bizarre situation of persuading some of the medical team about this as they tended to focus on her young age and not how sick she was due to her severe life limiting illness. In this situation the ITU consultants were really helpful and had fairly blunt discussions with the physicians about futility.
Of note like a poster above my Motger tried multiple times to discuss her resuscitation wishes while she could it was brushed of because she wasn't sick enough...she knew she was though. I work in hospital and life to change this culture. I would encourage you to talk about this thread with your families. What do you want??
My siblings hold health PoA for me. They know that if I am incapax I would prefer death to being left cognitively damaged. I accept that not everyone shares my views but this is my view.
CPR cannot stop the slow gradual decline of natural death in the elderly or sick. It is really fucking good when something acute and reversible happens eg. Blocking a major blood vessel, choking but even the it isn't always successful and some survivors pay a high price cognitively.
For the frail, sick or elderly it allows a peaceful death.
DNACPR discussions have forever changed family dynamics for us...although I remain health PoA for my aunt in the even of her losing capacity. Discussing DNACPR for her will be interesting as unless her views change she will want CPR but it is likely not to be in her best interests.
