I am just going to address the idea of a DNR in this post. Every DNR/DNI has to be signed by a physician and a witness. Most will not issue one unless you have a chronic condition likely to result in early death or you are terminal. They all say for you to be allowed to pass naturally, without intervention. So, say for example you are dying due to a car crash or other traumatic event. Your DNR doesn't cover that. If you actively overdose, hang yourself, ingest poison, tight a ligature to compress your carotid arteries, etc, your DNR doesn't cover that. And, I hate to say it, but if your family tells them to disregard your paperwork and decides instead to have medical care provided, it is often the case that they will, until the ethics committee gets involved and that could be days to weeks away, especially if there's function left in you, no matter how minimal.
I'll give an example, my grandmother had a DNR, which specifically stated no life-prolonging procedures or medications. She had dementia at that point and couldn't make her own decisions. The doctors explained to the family that without a pacemaker, she would die within days to weeks. One family member objected, for religious reasons, and they put the pacemaker in. My grandmother had a lucid period just before the pacemaker placement and called me to help her object. I discussed this with the doctors and they said the other family member was of closer relation and they needed to perform it despite her DNR/DNI with no life-sustaining procedures or medication. She got the damned pacemaker. It was AWFUL.
This is in a specific east coast state, your states may be different.
Also, look up the case of Terri Shiavo (I think that is the right spelling). If I remember correctly the mother wanted her discontinued from life support, and the husband didn't. (I might have the two actors in that scene backwards i their convictions). It took a really long time to get to court and have a decision.
