@Shawbridge I believe the agents have some discretion in interpretation of the MOLST or whatever other document you sign. You can certainly prevent CPR from being done, but you can leave leeway on artificial feeding, and respiration. Decisions for my mother were not guided by the MOLST. I had to make decisions as the proxy. She was DNR and that was the main thing that was achieved on paper.
Curious what folks think about my comments on dementia and quality of life. @Shawbridge are you sure that inability to communicate is your red line? I had a friend with progressive MS who stayed alive long after he could no longer talk. Though he did have a technologically advanced way to get his thoughts out.
